Mazda 3 TC Bodywork

We (CorkSport) showed off our work-in-progress TC America TC Class Mazda 3 race car at the CorkSport Mazda Showdown event on August 5th. If you are asking yourself why this is a big deal and why I am reading a blog post about it, here’s the explanation.

On October 1st, 2019, Mazda announced they would join the TCR ranks with the car attending the 2020 season opener at Daytona with IMSA. The bodywork was excellent; it captured the body lines and presented an absolute WOW factor!

4th Gen Mazda3 TCR Race Car

Unfortunately, the car was a no-show at the first round or any round scheduled in 2020. On August 15th, Emily Taylor from Mazda announced they had canceled the TCR program, citing the coronavirus as the explanation.

What About The Body Kit?

So what happened to everything from Mazda’s race program, and why is the bodywork a big deal? There were two sets of original molds made for the bodywork. The 1st set of molds went to the constructor Long Road Racing, and the second set sat at Mazda’s design center in Irvine, California.

The molds in Irvine were the first set made off of TCR “Show Car” bodywork and were not production-ready. The “Show Car” Mazda used for their 2019 announcement and future marketing campaigns wasn’t an actual race car. It was a production car with the bodywork on it, but the engine & drivetrain was stock.

TCAmerica Racing Car Mazda 3

CorkSport has been racing a 3rd generation Mazda 3 in the TC class for several years as the development tool for the Skyactiv Turbo kit we offer. 

When running in a professional series, the series works with manufacturers and wants the newest models competing on the track to keep the series fresh and relevant for marketing for both the auto manufacturer and the race series.  The last 3rd Gen Mazda rolled off the production line in early 2018, making our race car over a year old when the TCR program was announced and over two years old when the program was canceled.

We needed to race the 4th Gen Mazda 3s to keep competing in TC America,

The Journey For the Mazda 3 TCR Kit

This may seem like an exaggeration, but I spent over 200 hours on the phone, in meetings, writing emails, and talking with employees, ex-employees, and contractors that Mazda used to chase down where the bodywork went, who was ultimately in charge of it, and to see if we could get our hands on it.

Once I knew the molds still existed, additional meetings, phone calls, and emails were required before signing an, “OK, we will consider it. Your plan and history jive with a company (CorkSport) that can use the parts and provides a benefit to Mazda.” type of agreement. During this time, I learned the first set of molds had been destroyed, making the motorsports molds the only set left.

In October 2022, snagging the TCR bodywork molds became a strong possibility. I was headed to Texas to drop off some racing equipment to a friend. I decided to leave my truck and trailer in Texas since the bodywork molds were now located on the East Coast. If Mazda agreed we could pick up the molds in the next few months, the truck and trailer would already be halfway there.

December 12th, 2022, Mazda gave me the green light to gain access to the molds after several more phone calls, ZOOM meetings, and agreements were made. I flew back to Texas and headed to Multimatic in Mooresville, NC, to complete this epic quest. After one very long drive, including a massive ice storm, and making it home on Christmas Eve, Mazda’s TCR molds were at CorkSport.

Since then we have been planning and slowly building the new TC Car – We cannot thank Mazda Motorsports enough for choosing to partner with us as we continue to shape our racing program!

Rear wing is not to racing spec and was added temporarily to represent what it
might look like in the future – rear window will eventually be plexiglass.

Are These The Real Thing?

A common question that will get asked is, “I have seen the Mazda 3 TCR kit overseas, how is what you have the real thing?” Well, my friends, Technology and replication are a wonderful thing.

I asked the same question about the hill climb machine that TCP put together for Mike. If you compare the kits, you can see there are some differences in the kits with the aero, brake cooling, grill area, and more.

It was unofficially stated there were body scans done of the show car with Mazda Japan and those are the results. I cannot speak about the Thailand car but a handheld scanner and some import auto salon are my best guess.

Look forward to more updates on our build over the next several months, This is going to be fun!

Mazdaspeed 3 Lowering Springs – V2.0

Speed3 Lowering Springs

CorkSport is proud to announce the new and improved Version 2.0 Lowering Springs for the 2007 – 2013 Mazdaspeed 3.  While the changes are subtle, it never hurts to go back and refine a product that is so well loved by the community

When designing performance lowering springs we want to find the right balance in performance, comfort, and style.  When done right performance springs can make a huge improvement in the vehicle’s overall driving experience.  That is our goal at CorkSport HQ.

The CorkSport V2.0 springs are very similar to the V1.0 with a ride height drop of approximately 1.1” front and 1.2” rear.  This is a fairly aggressive drop, but does cooperate with the stock struts after a bit of bump stop trimming.  That is all clearly laid out step-by-step in the included installation instructions.

Now ride height isn’t everything.  While it looks great, it also needs to perform great.  The CorkSport Sport Springs have specific spring rates so that they perform and feel great for the spirited and daily driven Mazdaspeed 3. 

Up front the spring rate is a linear 3.5K and the rear is a linear 4.5K.   We specifically design the springs with a higher rear spring rate to help the vehicle understeer vs oversteer characteristics and maintain a proper suspension frequency so your Speed feel solid and planted through the curves and over road imperfections.

Overall, the car is going to feel more lively and connected to the road, giving you more feedback and control to enjoy your Mazdaspeed 3.  

You probably also notice a new color!  Yes, our new V2.0 are now blue via a durable and corrosion resistant powder coat finish.  

Thanks for checking out the new CorkSport Lowering Springs for the Mazdaspeed 3.  If you have any questions you connect with us via Facebook, Email or give us a call; we’d love to help.

Mazda 6 Turbo Down Pipe

Mazda 6 performance exhaust downpipe

Time for more horsepower and boost with the Skyactiv 2.5 Turbo engine.

The Mazda 6 just got its next upgrade in the form of the CorkSport Downpipe for 2018-2022 models equipped with the 2.5L Turbo engine. We took the OEM downpipe and improved on it in every way, including sound, flow, power potential, and even ease of install! Help unlock power with the Mazda6 Turbo downpipe and take a step forward to more making power!

Mazda 6 Turbo Downpipe for 2018-2022 Turbo

Stay Up-to-date with CorkSport   


The CorkSport downpipe uses a 2-piece design that starts with a cast 304 stainless steel bellmouth. This provides a high-flowing, smooth transition from the turbocharger to the piping that will stand up to the test of time and the high heat of the turbo. The piping is upgraded from the OEM 65mm diameter to 80mm mandrel bent piping to maximize flow and reduce restrictions. The bellmouth is joined to the piping using CNC machined v-band flanges which ensures a leak-free seal.

Mazda 6 Turbo Downpipe for 2018-2022 Turbo

The two-piece design is not all about flow through. We optimized the casting design to be easy to install and tighten all the hardware. Since you do not have the piping in the way, like you would with a one-piece downpipe, the mounting hardware at the turbo is very easy to access! Fitment is also spot on, as we used 3D scan data from the OEM downpipe when designing the CS downpipe. That means great fitment with your existing aftermarket exhaust, or even the OEM one! With exhaust, the CorkSport downpipe will change the exhaust note of your Mazda 6. With the full CS catback exhaust, we noticed a different tone with some extra “growl” and a very slight increase in volume. This goes for both the catted and catless setups, with just a hint more drone with the catless setup.

Mazda 6 Turbo Downpipe for 2018-2022 Turbo

All of the efforts to reduce flow restrictions are in the name of power! By smoothing the exhaust path and eliminating restrictions, the turbocharger can breathe better. While we have not been able to fully tune the car to take advantage of the flow gains (more on that later), typically an upgraded downpipe offers faster spool times, better peak power, and can help hold power better at higher RPMs. We hope to be able to test & validate the power potential of the MZ6T downpipe soon, but for now, know that the CorkSport Downpipe has enough flow capacity to efficiently support 500+ WHP, assuming you’ve got the mods to make that power!

Mazda 6 Turbo Downpipe for 2018-2022 Turbo

So the elephant in the room: tuning. While the CorkSport Downpipe can be installed and driven on an otherwise stock Mazda 6 Turbo, we strongly recommend a tune after installing the CS downpipe. There are some fairly strict limits to airflow and torque in the OEM tune that can result in some mild surging or “hiccups” especially when at wide open throttle. This is simply the car hitting those limits and pulling back power. We have experimented with these limits and have found no long-term effects of hitting the limits or even going beyond. They are very conservative limits for safety with stock parts. With more efficient parts, your engine works easier and is able to produce added power/torque and consume more air so the limits are simply hit easier.

Mazda 6 Turbo Downpipe for 2018-2022 Turbo

Let’s go through some housekeeping on the Mazda 6 Turbo downpipe. We offer the downpipe in both fully catless and with a high flow 300cel cat. As modifying or removing the primary cat is illegal in most areas, both options are sold for off-road or race use only. The fully catless setup will be the best for power gains but also comes with an all but guaranteed check engine light. The catted option cuts down on the smell of a fully catless setup but will sometimes still throw a CEL. This CEL can however be disabled with a tune.

Finally, what comes in the box with your MZ6T downpipe? Each kit comes with all the hardware needed for installation. This includes new turbo studs & crimp nuts, exhaust connection hardware, a Remflex exhaust gasket, and the stainless steel v-band clamp for connecting the upper and lower sections. Also included is a support bracket for the downpipe and even a custom heatshield to deflect heat away from engine bay components. Both come with required mounting hardware as well!

Gen4 Mazda 3 Turbo Performance Lowering Springs

Putting a turbocharged engine in the GEN4 Mazda 3 was a step in the right direction for Mazda but it still misses the mark of a “hot hatch”. Well, that’s where we come in! Introducing the CorkSport Lowering Springs for 2021+ Mazda 3 Turbo. We took what we learned from the naturally aspirated Mazda 3 and applied it to the slightly heftier turbo models. This resulted in a great new ride height and improved handling to push the GEN4 closer to a hot hatch, without ruining the daily driving comfort. Read on for full details and images of the great new look!

Red Mazda 3 Turbo Best Lowering Springs for 2021+ models

Let’s start off with what everyone wants to know: ride height! With only one driveline & transmission option, we could really dial in the ride height for both turbo hatchback and sedan models. The CS lowering springs for the turbo models offer a similar ride height drop to the N/A models. For the turbo hatchback, this means a ride height drop of approximately 1.5” in the front and 1.8” in the rear. For the slightly heavier turbo sedan, expect a drop of 1.5” in the front and 1.9” in the rear. While the sedan is a slightly larger drop in the rear than the hatchback, it still sits level and looks great!

This ride height is low enough to look great yet not too low to cause you issues on your daily commute. We found that this ride height can clear most driveways and speed bumps no problem. On really steep driveways, taking it slow and at an angle will help you keep your front bumper safe. We haven’t really found a driveway that was an issue though! One final note: we did test our regular, non-turbo Mazda 3 lowering springs on a turbo car. While they fit, the extra weight from the turbo system had the car sitting way too low in the front & looking ugly. We would not recommend doing this!

CorkSport Best Mazda 3 Turbo Lowering Springs red

Moving on to the next best benefit from lowering springs: handling! The CorkSport lowering springs offer some much needed sharpness to the MZ3-T. By lowering the ride height, you lower the center of gravity of the vehicle. Combining this with stiffer than OEM spring rates, body roll is reduced, which greatly helps driver confidence through the twisties. We carefully chose our upgraded spring rates to also help reduce understeer when at the limit of traction. By increasing the rear spring rate more than the front, your turbo 3 gets better turn in and more neutral handling.

2021+ Mazda 3 Turbo Lowering Springs

The final spring rate numbers for the Mazda 3 2.5T lowering springs actually surprised us. We tested a few different spring rate combinations to find the best balance of ride and handling. Ultimately, the same spring rates as the naturally aspirated Mazda 3 won out (this was due to both cars using the same suspension design). A 3.4K front spring and a 5.9K rear spring offered a compliant ride for daily driving, yet great handling characteristics on a backroad. The OEM dampers on the turbo models are just a hair stiffer as well, so the increase in spring rate fits fantastic with no bouncy ride!

Front Mazda 3 Turbo with CorkSport Lower Springs

Each set of CorkSport lowering springs for Mazda 3 turbo are made specifically to fit directly in place of the OEM springs. The only small modification that is needed is to trim the bump stops to allow for correct suspension travel before the bump stop is contacted at the new lower ride height. The springs are all made from high-tensile strength spring steel. This ensures a consistently performing spring that will stand the test of time and will not settle. We finish off each spring with a powder coated red finish. We chose red instead of the typical CS blue to help the turbo models stand out and because red things are proven to go faster! We even include a spring silencer on the rear springs to prevent any noise.

That about wraps up the launch of the CorkSport Lowering Springs for Mazda 3 Turbo. Check out the product listing at the link below for more pictures. Be sure to give us a call with any questions you have, we’re happy to help!

P.S. The car in the above images is riding on Advan GT wheels in 19×8.5 +38 size, wrapped in Kumho 235/35 R19 summer tires.

RX-Vision GT3

Widebody GT3 Rx Vision racecar goodness

I haven’t written any blogs in a while as there hasn’t honestly been anything from Mazda, which has made me stop and go WOW. Most people who have interactions with me would have thought I would be interested in the Mazda 3 TCR. The TCR car looks great, but when I learned Mazda went with the “Spec” engine for the series, it became a “meh” for me. Having an engine that is based on more or less a VW power plant pulling a Mazda around the track made it a lot less interesting. I do know why Mazda chose to go that path, but that is another story.

The next possibe rotary
Mazda Rotary GT3 Concept Car

What did make me go WOW recently was at the Grand Turismo Championships when Mazda announced the RX-Vision GT3 concept! Mazda loves a sexy race car, and if you look at the past two, they have both come out of the Mazda North American studios. This concept is no exception as Julien Montousse, the design chief for Mazda North America, was present during the announcement of the car.

The Mazda Rotary Rx-Vision GT3 Racecar

This is a big deal in my mind, we have just seen a change at Mazda USA with Nelson Cosgrove now appointed as the new director of Mazda Motorsports. Mazda has done everything except come right out and say we are going to build another rotary, and that message looks to be getting stronger. We have seen more patents popping up, calling out more tech and drawings of rotary goodness, including my favorite the top-mounted turbo rotary engine from years back.

Like anything Mazda teases us with, we will have to wait and see what happens. On a personal level, I hope Mazda gets us a 2020 Mazda 3 AWD turbo MT, but that is another one of those “wait and see” dreams from Mazda.
