To support the kit there have been a number of things done to the car the most major of which would be the AP Racing brakes on all 4 corners. I run a 14.25" front rotor with a 6 piston caliper and a 13" rear rotor with a 4 piston caliper. Stopping has never been a problem.The suspension is fairly involved as well including H&R Coilovers, H&R swapbars, BMR upper and lower control arms, and a-arms. I had intended to run the Agent 47 K Member unfortunately the turbo kit needs to be adjusted to make it fit since there is a single pipe that wants to be in just the wrong place.The transmission has been fully built by Pat Barrett at Level 10 to pretty much take any abuse I can throw at it complete with a larger trans cooler to keep it cool, a single piece aluminum driveshaft to help get the power out to the wheels, upgraded torque converter and shaft. :: STOLEN PHOTO ::This is the photo stolen from here (it's the only place it's ever been published) and used by Extreme Dimentions, BodyKits.com, StreeBeatCustoms and a number of others to sell products not even on the car. While Extreme Dimensions has removed the image many others continue to use it to sell nock offs of the Cervini kit. What is on this car is a true Cervini kit - it may be more expensive but remember you get what you pay for - better fit & better qualtiy!* the odd part is - there were better photos to choose from and this one is so obvious because of the windshield glare LOL.
