Why Lowering Springs?

Everything to know about lowering your Mazda with lowering springs.

Whether you want the better handling that comes with the lowered center of gravity, or you want to rid yourself of the wheel gap eyesore.  Lowering springs will give you want you’re looking for.

For running the track, or a spirited drive through the countryside, CorkSport lowering springs are the upgrade you’ve been looking for. By adding lowering springs and lowering the center of gravity of your Mazda allows the car to stay more planted to the road.

One of the biggest things to note on stock suspension is how far upward the suspension travels when hitting a bump. It can make the car feel like it wants to lift off of the road; depending on how fast you’re taking corners. Lowering springs help to correct the car’s suspension travel when you hit a bump in a turn.

Lowering springs also have about 25% increased stiffness. For the Mazdaspeed platform, increased stiffness in the rear is a must. Mazdaspeeds like to squat pretty hard when hitting full boost, so any way you can manage to stiffen up the rear is a great modification for your car.

Adding lowering springs also gives your baby amazing eye appeal and a much more aggressive look. Whether you drive a Mazdaspeed3Mazdaspeed6Mazda 3, Mazda 6, CX-5, CX-3 or MX-5, lowering springs will get rid of that ugly wheel well gap. The result is a Mazda that carries a much cleaner and more aggressive look and gives you the ability to take it to the track if you want to.

Drop your Mazda for an aggressive look and better handling with the CorkSport lowering springs.

Some people want to drop their Mazda as much as possible, and some don’t. CorkSport lowering springs don’t deliver a super aggressive drop. If you’re not interested in scraping your front bumper on every road bump, the CorkSport lowering springs have the right drop for you, and provide the increased handling capabilities you’re looking for.

The Mazda 3 Rear Motor Mount 2.0: Back & Better

2014 Mazda 3 rear engine mount upgrade

We here at CorkSport are proud to announce the relaunch of the Mazda 3 Rear Motor Mount.

Yes, you read that correct, this is a re-launch. At CorkSport we push ourselves to design and develop new and interesting products every day, with that, we try new and innovative manufacturing designs and methods in an attempt to create exceptional, competitive, cost-effective products for our loyal customers.

Sometimes those new and innovative manufacturing methods end up not being as awesome as we originally expected. This is just part of the designing and learning process. Let’s get into the details.

The original, let’s call it V1, Mazda3 RMM used a new-to-us manufacturing method of applying the polyurethane to the billet aluminum body called vulcanizing. The billet aluminum body and the steel sleeves are mounted in a fixture then liquid polyurethane was poured into the assembly and cooled until the polyurethane had set to the final hardness.  This process appeared to be very promising; each part was set up identically, it was nearly impossible to have any missing parts not sent to you, and most importantly the polyurethane was adhered to the billet aluminum body and therefore could not fall out.  More on that last bit later.

We moved forward with the manufacturing method and had a few samples made with various polyurethane durometers ranging from 60A to 80A.  After various testing, we determined that 70A was the best compromise of response and NVH (Noise, Vibration, Harshness) experienced by the driver. We continued testing for a few months to verify long-term durability and found no issues.  Hooray! We moved forward with production to get this new great Mazda6 RMM out the door to you.

Unfortunately, it appears that our testing period just wasn’t quite long enough.  Eventually, the polyurethane would fail but fail in a style we had never experienced before.  Long story short, polyurethane has excellent compression strength compared to the tensile strength.  The polyurethane was being pulled/split apart due to the forces of the engine.  

Now we had a few options of how to redesign the Mazda 6 Rear Motor Mount after going through the failure analysis.  

  • We could have simply stuck with the same design and just increased the stiffness of the polyurethane.  Increasing the durometer rating of the poly increases the tensile strength, but this would have resulted in an unsatisfactory driving experience for you which was unacceptable.  
  • The other option was to start from scratch again to create a new design that did not compromise the driving experience or the durability; with challenge comes innovation.

Again we went through many different designs, with the greatest challenge coming in the form of retaining the polyurethane pucks.  Typically the polyurethane pucks are retained by whatever the mount is bolting to, but with the Mazda motor mount, the steel sleeves extend far past the outer edge of the polyurethane pucks.  This leaves the pucks free to slide out of the billet aluminum body and cause a major failure.  

Using the conventional polyurethane puck style, we developed a design that would work, but more than doubled the number of parts needed which increased the chance for something to go wrong and drives up the cost.  This design is shown below:

 

The red arrows show the direction the conventional polyurethane puck would slide out of the body.  The red circles show the puck retention system to hold the washer and pucks in the body.  This retention design required many parts to be successful.

With the cost going through the roof we had to go back to the drawing board. There had to be a better way… and there was.  

The third major iteration shown above solved the problems of the V2 design and got us away from the vulcanized polyurethane of the V1 design.  Things were looking good.  With the V3 design, the polyurethane pucks are pressed into the billet aluminum body.  The pucks have ribs, shown with the red circles that are just large enough to keep the puck in place, but small enough to let the puck be pressed into the body.  

With this, we were able to make some clever designs to the RMM to keep it centered in the engine and chassis brackets on the vehicle.  The smaller diameter puck extends out to the ends of the steel sleeves; this keeps the entire rear motor mount centered.  The large diameter puck retains itself in the body and allows the associated steel sleeve free to slide for easy installation; shown with the red arrows.

Now… does it work? YES! Pretty fantastically, we might add!  

We have had this design on a handful of vehicles, one of those being the CorkSport Mazda 3 Racecar during the SCCA Run-Offs at Indianapolis Speedway.  Other than some dirt and grime, the tested RMM looks great.  

You were probably expecting this blog to be all about the details and reasons you should buy this performance RMM for your Mazda 3, Mazda 6, or CX-5.  All those details can be found on our website, and I invite you to check them out.

What we really want to get across here is this:

First and foremost, we will always do the best we can to take care of you and your car if there is ever an issue or concern with your CorkSport part.  

Second, if you are a driving enthusiast, if you go driving for the sake of just driving, then you need this RMM in your life. It will completely change and improve your driving experience, plain and simple.

Superior Stopping Power for your Mazda 3, Mazda 6 and Cx5 with our Big Brake Kit

After a long wait and a lot of testing, we’re proud to announce the launch of the CorkSport 4 Piston Big Brake Kit for the 2014+ Mazda 3 and Mazda 6, and the 2013+ Cx5.

Why upgrade your brakes to something of this level?

On our own 2015 Mazda 3 SCCA race car, we’ve found that even mildly increased power levels can burn up the stock brakes on the track. We melted the OEM dust boots off the stock calipers after two race weekends, which is not a good sign for the longevity of OEM components.

corksport-mazda-3-big-brake-kit

CNC machined from extremely lightweight billet aluminum, the CorkSport calipers use an opposed piston design that is fixed to provide highly improved pad wear and caliper rigidity over the OEM design. At just over 7lbs, the aluminum CorkSport Big Brake Kit shaves almost 7lbs of unsprung weight off each corner of your Mazda 3, all while adding more stopping power and a much better pedal feel.

Available in 3 anodized colors, this brake system includes everything you need to easily upgrade your stock braking system including: high strength steel brackets, calipers, slotted brake rotors, stainless steel braided front brake lines, brake pads, and all necessary hardware.

The 2014+ Mazda 3 Big Brake Kit has the following features:

  • Superior Construction: Crafted from billet aluminum and made to last with durable components.
  • Longevity: With dual O-rings far away from the brake pads, these calipers are able to handle much more abuse than typical dust boot equipped calipers.
  • Lightweight: At just over 7lbs a side, this kit saves almost 7lbs of unsprung weight per corner!
  • Versatile: Designed around a popular brake pad style (Hawk #HB750), you can use almost any brake pad compound available on the market.
  • Available in Three Colors: Choose from black, red or blue in a durable anodized finish.
  • Ease of Use: With simple hand tools you can change brake pads in minutes and you are able to rebuild, so you can be back to factory fresh brakes in no time.
  • CorkSport Service and Support: Receive full-color installation instructions, all of the needed installation hardware, and knowledgeable telephone support.

The New CorkSport Mazda 3 Rear Motor Mount

Feel like your SkyActiv-powered Mazda is lacking a bit of throttle response and driver feedback?

We hear you, that’s why we’re introducing the all new CorkSport Race Rear Motor Mount for 2014+ Mazda 3 and Mazda 6, as well as 2013+ Mazda CX-5.

CorkSport Mazda 3 Rear Motor Mount

Manufactured from 6061-T6 aluminum and anodized, the CorkSport Race RMM is strong, durable, and lightweight. What truly sets the CorkSport Race RMM apart from the competition goes to the 70a polyurethane. This RMM does not use polyurethane inserts that can loosen up and degrade. The 70a polyurethane is poured directly into the mount for a permanent bond with the aluminum body and bushing collar.

CorkSport Mazda 6 Rear Motor Mount

More than a handful of prototypes have been tested to ensure that the product arriving at your door is the very best it can be. We tested different durometer polyurethane from 60a to 80a (as well as different bushing sizes) to find the maximum improvement of throttle response and driver feedback without excessive noise, vibration, and harshness. Check out one of the prototypes below.

CorkSport Mazda CX-5 Rear Motor Mount

Now you might be thinking: “How does a motor mount improve throttle response and driver feedback?” In FWD vehicles it is typical for the engine to be oriented in a transverse layout. This means the engine is parallel to the axle centerline, whereas in a longitudinal layout (typical of V8’s and RWD vehicles) the engine is perpendicular to the axle centerline. Anyway, the engine/transmission applies a rotational force (torque) to the drive shafts, in turn rotating the wheels/tires forward.

“For every action there is an equal and opposite reaction.” – Newton’s third law of motion.

The amount of torque applied to the wheels is equal and opposite to what is applied to the engine itself, but what keeps the engine from just rotating? Enter the engine mounts. Unfortunately, the OEM engine mounts are very soft, so the engine is able to move and rotate substantially while driving. This makes for a very plush ride inside the cab, but sacrifices throttle response, driver feedback, and really the general driving experience. Replacing the RMM drastically reduces the amount of rotation the engine is allowed which in turn forces more of the engine’s torque to the tires sooner instead of just rotating the engine in the engine bay. This holds true for any action that affects the engine: throttle inputs, up-shifting, down-shifting…etc.

Improve your vehicle’s performance with the CorkSport Race RMM, and pair it up with the CorkSport Short Shift Plate and Shifter Bushings for the ultimate performance package!

Top 5 Tips for Family Roadtrips in your Mazda

Dear Car Guy,

Hope this finds you well and enjoying the switch in seasons.

Wanted to give a shout-out to all of you Car Guy’s that are also Family Guy’s! You’re THAT guy that keeps his car clean regardless of the amount of french fries and jelly belly’s that are left on the seat after you’ve removed the car seat. You’re also the guy that gets to load everyone in your AWESOME ride because it’s highly likely that your wife hasn’t cleaned out her car in what seems like decades. So the dog, the kids and the luggage all get to replace your sound system in the back for the weekend as you go off to visit family for the upcoming holidays.

Here are some tips, since I know you’re always into life-hacks that keep your car in pristine condition, and to make your extended car rides a little bit more tolerable with family!

#1. Lay down plastic. NoCar Wrap Kidding!

Grab some painter’s plastic and lay it over your seats with holes for the seatbelts, and you’re less likely for spills to stain and cause a permanent mess. Not to mention when you’re done with the trip, be it out trick-or-treating, or heading to be with family for the weekend, you can just scoop up the dirt, broken crayons, half eaten suckers and candy wrappers all at once. Better yet, if you can convince the screaming kids and wife, don’t let anyone eat in the car 😉 If you have to… Here’s an idea: https://diningwithalice.com/twin-cities-live/travel-snacks-for-kids/

Candy Organizer

#2. Travel the road less traveled.

Those winding twisting, exciting roads will rock the kids and screaming tots to sleep (if you’re lucky, the wife too!). Leaving You with nothing but the wheel, the road, and some thinking time. (Please be careful with these roads as the weather gets worse). I love this way, even if it takes 20 minutes longer, it’s worth it for the silence and fun.

#3. Use your coats (full sized adults) and zip them over the front seats.

Keeping the little feet from leaving foot prints and stains on the back of your seats. Or use something like this: Seatback Protector

Seat Cover

#4. Put a full size towel, in a plastic bag and leave it in the wheel well of your spare tire.

This would be perfect for the unexpected messes or dogs that run off into the lake. We all know that someone will have an accident, spill a drink, forget a favorite blanket, or will inevitably fall into the only mud puddle seen for miles. Be prepared for our furry friends it always seems like it was on purpose!

#5. Embrace the show tunes, it’s highly likely your kids are into some form of musical torture.

If you just embrace it and sing along they’re less likely to want to continue with that soundtrack. What better than the voice of Dad over the “Frozen” theme song to annoy the kids, or a great rendition of Miley Cyrus screamed in your best falsetto. Unless you’re into the same song on repeat….

HIMYM

Don’t worry, we’ve taken these ideas from the Dad’s here, and they really work. So find a way to “Let it go”, and yet still protect your favorite ‘baby’ from your beloved brood.

Stay Safe, Stay happy, and Enjoy the ride!!
