Thinking about getting these for my 2010 mazda3. I already bought my own 17 x 7.5 wheels, do you think I would still be able to get wheels spacers and fit them in?

CorkSport Reply:Check out the FAQ for the Coilovers for an answer.
Great product thus far, interesting design. I wasn't a fan of having to cut to strut towers in order to install the camber plates but it is what it is. Just so everyone knows, a 245/40 tire will need a fender roll in the front if you plan on going any less than a 1.5 finger gap. Also, you will definitely have to roll the rears as well.

Damper adjustments are easy to get to which I really like. You'll have to take off the front wheels to get to it in the front but with the backs you can just lift and there's usually enough clearance to get your hands to the adjustment knob.

With the fronts, you can adjust the height in the same fashion as adjusting the dampers in the back. All you need to do is lift and put your arms in. Although, you are required to go under the car to adjust the rear height.
If you plan on buying any coilovers for your speed these are it! I love the smooth ride you get while handling is awesome. I have had many coilovers including KW and for the price these CS blow them away! (1 smooth-10 Hard) I rank a stock speed 3 ride comfort a 5 and with CS coilovers a 6! (1 hit the wall-10 on rails) Handling rank for a stock speed 3 a 4 and with CS a 8 my opinion only! GREAT JOB CS keeping quality high and price low!
I am curious as to what sleeves you guys are using on these and what rear perches you use for the rear springs. I already have Koni Yellow shocks and wish to convert them to coilovers, but I'm having difficulty finding a perch for the rear springs so that I can stay in my current SCCA class.

CorkSport Reply:We are not using sleeves with our kit. The threads are machined into the body of the damper. The rear spring adjuster is our own design.
Does this kit include everything i will need to install?

As in, is there anything I will have to go out and pick up seperately in order to install these and have the car function properly?

Also, these are compatible with a 2007 Mazda 3i sport 4 door sedan, correct?

CorkSport Reply: The kit includes everything you will need to for installation. If you plan on going really low a set of rear camber arms may be required. The kit will work great on your 2007 Mazda 3.
Will you guys be making a EDFC system for these?

CorkSport Reply:We do not have any plans to.
They look so good! Do they fit on a 2.0 Mazda 3? Also do use ship to Australia?

CorkSport Reply:The coilovers fit the 2.0 models. We have a dealer located in Australia MPS garage and we also offer shipping there.
I had the previous post asking about the clearance of 19 inch wheels. I meant 235/35/19 size tires. Not 29! I also noticed that the corksport project car has 19x8.5 wheels, but no mention if they were paired with your coilovers.

CorkSport Reply:Our shop car ran 19x8.5 wheels with a 235.35.19 tire. With the camber set correctly in the rear no rolling of the fenders were required. Our car was the test vehicle for this suspension kit.
Will I need spacers or rolling of my fenders if I pair your coilovers with 19x8.5 wheels with 235/35/29 tires? Basically how low can I go and will there be any contact with the inside of the wheel and the coilover?

CorkSport Reply: 29 inch wheels are something we do not have experience with on the Mazdaspeed 3/Mazda 3. We feel they take away from the cars styling and slow down the car too much from the added weight.
These things are phenomenal! I bought a set for my 2012 Mazda 3i to go autocrossing in the Street Touring FWD class. With nothing more than these and good tires, my otherwise stock car easily beat up on most other cars. Most recently, I attended our divisional championships where I competed against last year's national championship runner-up and ended the day in first place 0.3 seconds ahead of him. I am 100% convinced it is the Corksport coilovers that allowed my car to do so well. The standard spring rates are excellent and make for a perfectly balanced car when combined with a bigger rear sway bar and performance alignment. I couldn't be happier with these coilovers and definitely recommend them to anyone looking for the best performance, full adjustability, and a decent ride. Corksport has done its homework on these, and it shows.
