Your Suspension Questions, Answered

We get quite a few comments (okay, a ton) on our reviews and FAQs page asking questions like: will these wheels fit, will my car scrape, what do I do after I instal, etc. With so many questions coming in recently, I wanted to address this topic.

Will my car scrape speed bumps?

With any of our CorkSport springs sets, you shouldn’t have any problems with normal traffic control devices if taken at the posted speeds with stock Mazda body work. If you try to be Ken Block in your Mazdaspeed 3 and launch the car at 75mph you will scrape on the launch and landing.


Will my wheels rub?

With the OEM wheels, you won’t have any rubbing problems with our springs. We engineer our springs to be comfortable and most have an increased spring rate of 5-15% over OEM. With the car sitting lower, it’s possible to hit bumps with a heavy load but you shouldn’t rub unless you have a suspension alignment problem. On the second gen Mazda 3/Mazdaspeed 3s, the rear acceptable suspension range is already wide and if you plus size the diameter and wheel width you can run into some clearance problems. We found after an installation of the springs, the rear camber was -2.2 degrees on one side with no rubbing and -1.0 degrees on the other side with rubbing. To fix this, a set of adjustable rear camber arms is required to set the suspension even between both sides to give the wheel clearance and keep the alignment within specs.

Will these wheels fit my car?

Let’s make this easy. Go to and punch in the numbers. Google is your friend. Use a tape measure to see how much clearance you have on the inside against the suspension and the outside against the body work.

Will I need aftermarket wheels to run your springs?

You will not. We test our springs on the OEM wheels for all Mazda models we offer springs for.


Will I need to align my car after installing the springs?

Yes, you will. The toe settings on the suspension will be affected which will cause excessive tire wear if not corrected after installing any lowering springs.


Will I need to roll my fenders/guards/wheel wells?

If you want to run a different offset wheel, and the clearance is going to be tight, it’s a good idea to roll them. You won’t have to roll your fenders with the OEM wheels.

Have a question we didn’t answer here? Feel free to post a question in the comments or in the FAQs page of our website.

Product Release! CorkSport Coilovers for Mazdaspeed 3 and Mazda 3

I know many of you have been anticipating this release. Well the day has finally arrived! CorkSport is pleased to announce the release of our all new Coilovers for the Mazdaspeed 3 and Mazda 3!

Offering superior handling without sacrificing comfort, the CorkSport Coilovers feature 15-way adjustable dampening settings and full length adjustment that can be lowered -.8” to -2.5” in order to meet every drivers handling desires.

The CorkSport Mazda 3 and Mazdaspeed 3 Coilover Kit is manufactured using chrome silicon metal alloy with a cool bend process that give the springs strong tensile strength while offering precision down to 10/100th of a kg.

The front springs have been designed using a linear 7k spring rate with helper springs for a more comfortable ride and include 45mm inverted gas filled dampers to maximize unsprung weight, reduce side loading, and increase efficiency.

Also included with the front coilovers are front adjustable camber plates to replace the factory rubber mounts. The camber plates add additional adjustability with up to 3 degrees of negative camber and are designed with built in M10 studs for easier installation and solid pillow ball bearings and housing to reduce unwanted upper strut mount deflection.

The rears have been designed using a progressive style spring to compliment the linear fronts for improved handling and steering control. The pillowball mounts have been designed to provide additional feedback by eliminating the deflection in the OEM rubber bushings. A spherical bearing is used in place of the rubber bushing for improved tire grip and more accurate wheel alignment.

The CorkSport Coilovers have been fully tested and every damper is tested for compression and rebound. They are also fully rebuildable, making them a long-term solution for your suspension set-up.
