Stand Out with the Wing Extension for Your 3rd Gen Mazda 3 Hatch

Already have the Mazdaspeed “MS” style spoiler for your 3rd gen Mazda 3 hatch, but looking for just a bit more unique look? CorkSport is proud to announce our Mazda 3 Gurney Flap Style Spoiler Wing Extension just for you.  Designed for the “MS” style aftermarket spoiler on the 2014-2018 Mazda 3 Hatchback.  This is an aftermarket spoiler, not the OEM spoiler.

 3rd Gen Mazda 3 Hatch Gurney Flap

While the “gurney flap” style wing extension is not new to the automotive aftermarket community, we wanted to offer our interpretation of this fun, useful and stylish performance part.  We approached this design with the goal to add style, and some function, and durability. 

2018 Mazda 3 Hatch Spoiler Extension

With such a simple performance part how can we be unique and durable?  That comes down to the design and materials…more specifically the combination of those two.  The common option on the market today uses a plastic material for the “flap”.  This is cost effective, looks decent, and has decent durability.  However, over time the plastic may degrade due to use, weather and UV radiation.

The CorkSport “flap” is made from 5052 Aluminum sheet and then powder coated a satin black for a durable and long lasting finish and construction.  Mounting the “flap” are three CNC formed stainless steel brackets and four underside mounting screws…also stainless steel.  This gives you a total of seven mounting points meaning there is no need for messy and finicky double side tape.

While we cannot make any official claims to added down force, we have found the car to feel more stable at speed and a little gurney flap never hurt anyone.  It sure looks good on the Tail of the Dragon mounted on Bradon’s 3rd GEN Hatch!

Measuring at 4” in flap depth, the CS design is a very noticeable as you walk up to the car with a pronounced flap and tumble polished stainless brackets.  All the underside hardware is black stainless so it blends into the satin black powder coat.

It’s Go Time with The Mazda 6 Turbo Kit

Do you ever find yourself in a situation where you could have used another +100hp? As in, getting on the freeway safely or trying to beat that minivan at the red light so you don’t miss your next turn? Maybe you know a guy with a WRX with a muffler delete, and he just won’t shut up about how “fast” it is. Well, let me tell you, my 2016 Mazda6 GT will do all of that in comfort and style! I’ve been lucky to be the first person in the world to run CorkSport’s Turbo Kit on a Mazda6, which also happens to be an automatic! #ridetheunicorn

I bought the car in early May 2022, and by the 31st, the CorkSport engineers had transformed my naturally aspirated Mazda into something special with the CS Turbo Kit. Flash forward a little less than a week out, and I was on my way to @Idaho Mazda Takeover to show off the kit. It’s a 450-mile trip one-way from my house to Caldwell, ID, and does not include the +300 miles of community shenanigans I completed while I was there.

As a testament to the CorkSport Mazda 6 Turbo Kit, I made the journey without a second thought. I averaged ~75 mph and snagged over 32mpg on the way there. This included spirited driving, stretching the car’s legs, and putting it through its paces, up, over, and through those difficult passes in eastern Oregon. I need you to understand this was a 100% stock Mazda6. The only thing we did was install our turnkey kit. In less than a week, I put over 1200 miles of “FUN!” on the car and have not looked back!

The CorkSport Mazda 6 Turbo Kit

The car drives as it did right off the dealership parking lot; it’s quiet and very tame, with a stock catback. You lightly press the throttle, and the car’s cab starts to fill with all the right induction noises. Hearing that turbo spool up for the first time sent chills down my arms; I couldn’t believe it. My Big turbo Mazdaspeed3 isn’t even that seductive. But that’s only part of the fun…

When you drop the hammer, the auto transmission immediately puts in the work. I was surprised at how quickly it locked up the torque converter and rocketed the car down the road the first time I drove it. I was worried about the implications of having ~80 additional whp rifling through it. After a few deep dives into how these transmissions work, I feel more confident than ever about the Mazda 6 and Turbo Kit, and the last 10K miles of beta testing have been trouble-free.

* This is Mazda 3 Manual Dynograph

I’d never driven a boosted automatic before, let alone an aftermarket one, so I didn’t know what to expect. What I’ve experienced has been more than I could bargain for. By design (of the OTS Professional Tune), you only use the boost when needed; otherwise, the car will drive like it’s not there if you want to go that route. However, if you mash the pedal to the floor, it’s “Go time!”

Since installing the turbo kit, I’ve supplemented this turbo kit with our 2014-2017 Mazda6 Catback. The stainless T-304 has enhanced this whole experience. The 90mm tips look great with those shiny resonators behind the rear bumper. It is starting to dial back on the sleeper, sleek and numb daily, and gearing more towards a fun, fast and capable 4-door sedan. The exhaust added around another 30whp and has me sitting comfortably near 260whp to the front wheels.

It didn’t take long for the numbness of the stock mounts to get to me. With this big bump in power, I wanted to do everything I could to help this car out. I installed the CorkSport transmission and rear motor mount, further evolving the turbo Mazda 6. Power delivery is now immediate and linear vs. the OEM mounts allowing the engine to bounce around.

A lot of us have very similar ambitions for our cars. We tend to create this inseparable bond between ourselves and the machine we’re driving. Having an OTS turnkey turbo kit that does precisely that is nothing short of spectacular. CorkSport has done an outstanding job offering a turbo kit that includes EVERYTHING you need, including a professional tune, battery, boost gauge, and boost controller. Heck, you even get Unicorn swag too!

Mazda 6 Turbo Kit Manifold

I’ve created a new sense of ownership by taking this project on; it’s changed my view on what I wanted from a car. This kit checks all the boxes in my book and has surprised me almost daily. My whole experience with the Skyactiv-G + CorkSport Turbo Kit has been rewarding. I cannot wait to push this car to its limits and beyond to see what these engines are truly capable of. 

If you have a 2.5L naturally aspirated 3rd Generation Mazda 3 or Mazda 6 sporting a manual or automatic transmission and want to get the most out of your ride – don’t hesitate to grab one of these turbo kits – the results are unthinkable!

Improve Your Braking with the All New Big Brake Kit for the Mazda CX-50

Introducing the CorkSport 13” Big Brake Kit for 2023+ Mazda CX-50 owners! This includes both the Turbo and non-Turbo models! The CS BBK improves braking performance with larger diameter rotors and 4-piston calipers. Also included in the kit are stainless steel braided brake lines and all the brackets and hardware needed for installation. It’s an all-in-one package that makes it just as fun to stomp on the brakes as it does to hit that skinny pedal! Read on for more details.

To start off, let’s look at the CorkSport brake rotors. The CS rotors are 13” (330mm) in diameter and 1.20” (28mm) thick. The OEM Mazda CX50 turbo uses 12.79” (325mm) rotors and 0.98” (25mm) thick rotors. This change provides for more braking torque to be generated from the same amount of braking force. Think like how a longer wrench makes it easier to loosen a stuck bolt. The added thickness and diameter is also simply more mass for the brake system to reject heat into. This keeps your brakes from overheating for much longer than the OEM units.

The CS rotors are not all about size however, they also have a decent amount of tech built in to further help your braking performance. Each rotor is made up of two pieces. A center “hat” is made from aluminum and an outer “ring” is made from a more typical rotor material: iron. The center hat uses aluminum for its light weight and rapid heat dissipation. The rotor ring uses iron for long lasting and reliable function. To further improve cooling efficiency the rotor has special “vanes” in between the inner and outer faces to further help with brake cooling. These vanes are directional and help to draw air through the rotor while the rotor is spinning. The rotor rings are also directionally slotted to help sweep away brake dust, gases, and any other debris that may affect your braking performance. The two piece design has the added benefit of cost savings as when it comes time to replace them. You can simply give us a call to purchase replacements of just the rotor rings instead of the entire rotor!

Moving onto the calipers, the CorkSport BBK uses 4-piston calipers made from forged aluminum. The use of forged aluminum is critical in reducing weight and maintaining rigidity.  Typically, OEM calipers are a single piston sliding design due to its compactness and low cost to produce.  This is fine until you start pushing the brakes harder.  The sliding design tends to flex and move around when in use and can reduce the confidence in your brakes.  With the more rigid and opposed piston design of the CorkSport Caliper, you can really push the brakes and hold them there with confidence.  Great for the street and trail.

Having many small pistons in the calipers also allows for maximized brake pad area that will wear evenly. Brake pad wear is also evened out by having pistons pushing from both sides of the caliper instead of just one like OEM. We even stagger the pistons within the CS calipers, making the leading edge piston slightly smaller, to really ensure even and consistent pad wear. The result is a brake pad that has 32% more surface area in contact with the rotor.

Finally, each piston in the CS calipers is made from stainless steel. Stainless was chosen for its low coefficient of heat transfer. Compared to aluminum or regular steel, stainless will transfer heat slower, meaning your brake fluid stays cooler for longer so you can stay out on track longer.

The CorkSport calipers come pre-loaded with upgraded brake pads that slot in fairly well between a street pad and a full on track pad. For the street, they offer low noise in most situations, with a squeak here and there when coming to a stop, and relatively low dust. On a backroad or track, they offer good performance when cold, and even better performance when warmed up a little. For extended track time, we do still recommend a full track pad, but for auto cross or a short hot lapping session, the default CS pads work well. Thankfully, the CS calipers use a standard brake pad shape, so you have plenty of options from the big name brake manufacturers.

Each CorkSport BBK comes with all the brackets and hardware needed for installation. We use high strength billet caliper brackets for rigidity and consistent caliper placement. All the hardware that keeps your brakes attached is grade 12.9 with a corrosion resistant coating. We even include stainless steel braided brake lines with each kit. The brake lines offer a stiffer and more consistent pedal feel. Even with all the added complexity, the CorkSport BBK ends up drastically lighter weight than the OEM turbo brakes (approximately 6 lbs lighter on each side).

To fit the CorkSport BP Mazda 3 Big Brake Kit, it is much easier with 17” or larger aftermarket wheels. Typically an aftermarket wheel will have much more brake clearance than an OEM wheel. You can use the 18” OEM wheels; however, for enough clearance for the large calipers, we found that you need a 10mm spacer. With that much spacer, we strongly encourage purchasing extended wheel studs for safety. In either case, we have a template available that you can cutout to check clearance to your wheels.

The Performance Rear Motor Mount For 4th Gen Mazda 3 is Ready For Action

If you’re looking for a performance part for your Gen 4 Mazda 3 & CX30 to elevate the driver experience then the CorkSport Rear Motor Mount. This CS RMM is designed to fit any 2019+ Mazda 3 & CX30 whether it is AWD or FWD, Turbo or NA, MT or AT. The key focal point for this RMM is to offer the driver additional feedback for what the car is doing when driving hard. The CS RMM helps eliminate the excessive engine movement, increase throttle response and provide a more solid shifter feel if you have a car with a stick.

Starting with the main body of the CorkSport RMM, it is manufactured from A356-T6 aluminum to provide a robust and light weight mount that effectively replaces the quite large and heavy OEM mount. The factory mount features a large rubber center section which contributes to the excessive engine movement and additional weight. For the CS RMM we decided to add smaller bushings towards the front and back of the mount which allowed us to save material and weight.  Below you can see the two RMM’s compared against one another.    

Mazda 3 Performance Race Poly Mount

Now onto the polyurethane bushings, which play a big role in the increased driver feedback and reduction in engine movement. We tested the selected 70A bushings extensively and found that they offer a good combination of providing both a noticeable improvement in the driving experience while not introducing to much extra noise, vibration, and harshness (NVH) into the mix for daily driving.

NOTE: NVH (noise, vibration, harshness) is a standard term used in the automotive industry.  NVH is a byproduct of changing some OEM components to aftermarket components in the pursuit of focused performance. Example of components that can increase NVH: engine mounts, clutch/flywheel, intake, exhaust, suspension, tires/wheels…and many more. 

During the first stage of testing we started out with only two poly bushings in the front of the RMM, but after further testing we found that adding an additional two bushing to the rear of the RMM provided much lower NVH while still reducing engine movement considerably.

The last piece that is fundamental in the CS RMM is the bushing sleeves. The sleeves provide the ability to install hardware through the polyurethane bushing without having the bushing itself compress and possibly crack when applying torque to the bolt and instead transfer the force into the sleeve. The bushing sleeves are precision machined out of steel for strength and then zinc coated so they will not corrode over time and wear out the polyurethane bushing prematurely.

Ok, so now how does the CS RMM improve the driver experience? Well, the factory RMM allows the motor to rotate a good amount which helps provide a smooth driving experience for around town, but this increase in engine movement decreases the throttle response and shifter feel.

This is because the motor is allowed to rotate a certain amount before the wheels do, so by decreasing the amount the motor has to rotate, allows the wheels to start rotating sooner, thus increasing the responsiveness of the car. This reduction of movement also provides a better shifter feel if you have a manual because there is less movement between the connection of the shifter and transmission.

What to expect from the Rear Motor Mount:

From our testing in multiple R&D cars and beta tester cars and the thousands of miles driven…it’s awesome!  From about 2000rpm up to redline you are going to feel a smooth engine that loves to give you feedback on your throttle, shifting and engine braking.  Below 2000rpm to idle you may notice some vibration, especially when the A/C pump is in operation.

Announcing The Turbo Kit 80mm GEN3 2014-18 Mazda 3 Cat Back Exhaust

 SkyActiv Mazda 3 Cat Back Turbo Exhaust Kit

Around 3 years ago the 80mm Cat Back Exhaust was released for the 3rd Gen Mazda 3. During this time many have enjoyed the increased sound, performance and looks that it offers. As we have been developing the Turbo Kit for the 2.5L 3rd Gen Mazda 3, we have also had a chance to refine and tune the 80mm Cat Back Exhaust to further improve the tone and sound of the exhaust while reducing drone for 3’s equipped with the Turbo Kit. That is why we are excited to release the Turbo Kit specific 80mm Cat Back Exhaust to those of you who have or are looking to pick up the Turbo Kit for your 2014-2018 2.5L Mazda 3.

2014-2018 Mazda SkyActiv Turbo Exhaust

With the original 80mm CBE installed on our Turbo Kit equipped Mazda 3, we found that while the sound was good, the drone it created in the cabin was too aggressive for our liking. To combat this we tested multiple different combinations of midpipes and axle backs with different resonator configurations to find the best solution. From this testing we found that the combo that worked best was to keep the same midpipe setup, but to modify the axle back so that no resonators were used. This resulted in a substantial reduction in drone while adding in a more aggressive tone at higher RPM’s. With that being said if you are upgrading from a stock or 60.5mm exhaust it will be a large increase in NVH (Noise, Vibration, and Harshness) but this is offset in our opinion by the tons of fun noises it offers. Since the axle back is the only component that has been changed for the Turbo Kit specific exhaust, if you already have an 80mm CBE and want to upgrade, all you have to get is the non-resonated axle back to take advantage of the reduced drone and improved sound. To get a good idea of how the 80mm CBE will sound during different driving conditions, check out the video below.

Aftermarket Turbo Back Exhaust Mazda3 2014-2018

The Turbo Kit 80mm CBE also provides the same great appearance of the original 80mm CBE. Both the sedan and hatchback exhausts feature 100mm or ~4” tips. On the hatchback this helps fill out the bumper cutouts and the slant cut design helps them match the flow of the bumper profile. The sedan on the other hand, features a single wall design so that water and other debris don’t get caught in the tip since they are hidden behind the bumper and angled down. No matter which model you have, these features help the rear of the car stand out and provide an aftermarket look that is subtle and classy as it should have been from the factory.  

Performance Turbo 2014-2018 Mazda3 Exhaust

The great build quality and material are also carried over from the original 80mm Cat Back Exhaust with the use of T-304 stainless steel that is polished to a mirror like finish. This helps keep the CBE looking new and protects against corrosion for a long time to come. All joints are TIG welded to ensure durability along with a nice appearance. The resonators use a flow-thru design so exhaust flow remains uninterrupted while drone is kept down. Check out the product page for more pictures and details on the Turbo Kit 80mm CBE
