Back and better than ever! The CorkSport Adjustable Front Upper Control Arms for Mazdaspeed 6 provide improved handling and easier wheel fitment through front camber adjustability. An impressive 4.5 degree adjustment range (+0.5 to -4.0) ensures you are able to get the camber you want. They enables you to dial in your handling for the track, correct your added camber from lowering, or even just dial in more camber for that new wheel and tire setup!
The Mazdaspeed 6 in the images is equipped with 255/40R18 Toyo Proxes Sports with 18x9.5 +45 Enkei GTC01RR. The front has a 10mm spacer for brake caliper clearance and the rear 3mm for trailing arm clearance. Camber is set at approximately -2.8deg all corners
The main gain from the CorkSport Adjustable Control Arms is the ability to modify the OEM camber setting. By loosening the four bolts on top of the control arm, you can easily adjust your camber, even without removing a wheel. Correct your camber from lowering or from a pothole strike, optimize your alignment for the track, or add negative camber to get the stance you want to fit that new wide wheel setup. At CS lowering spring height (1.5” lower than OEM), our local race alignment shop measured an adjustment range of approximately +0.5° to -4.0°. They even complimented how easy the arms are to adjust!
The MS6 Adjustable Control Arms completely replace the OEM upper control arms. When replacing such a vital suspension component, we knew it was crucial that we nail fitment to prevent any strange handling characteristics. We designed directly off the OEM control arms so you can truly bolt the CS control arms in with no modifications necessary and no strange changes to your car’s handling. We also tested the full camber adjustment range throughout the suspension cycle to ensure nothing will rub or cause damage during spirited driving.
The CorkSport Adjustable Upper Control Arms have gone through extensive testing on the street and in the twisties. We have had an early production sample on an MS6 for 6+ months. This car is setup with -3° of camber and is running 255/40-18 summer tires on a 9.5” wide wheel; a setup which is hard on parts. We have seen consistent performance out of the CS control arms with no issues whatsoever! We have seen a marginal improvement in handling feel as well, from the spherical bushings in the CS control arms. These replace the OEM rubber bushings and reduce some slop in the steering.
The CorkSport Adjustable Control Arms are made from A513 steel for long lasting strength and durability. The arms have gussets for added strength and are finished off with a black powdercoated finish for a long lasting & great look. New ball joints are included along with a fresh castle nut and cotter pin to keep things secure.
