GTO 4 piston Rear Conversion Summary

This rear bracket kit (aka ITSME4G63 C6 Z06 Kit) allows you to bolt on 4 piston rear CTSV Brembo Calipers onto your GTO utilizing the rear C6 Z06 Corvette rotor (13.4”/340mm). An 18” wheel (stock GTO 18” wheels clear )is a minimum requirement for fitting the 4 piston rear Brembos. Bolt in design, retains use of stock GTO brake lines & handbrake (half-moon spacers are used to raise e-brake assembly to rotor). Fit all model years (04-06). For Off-Road use only. 

Note: Requires Corvette C6 Z06 (MY 2006-2013) rear rotors (13.4”/340mm Diameter). Minor modification to rear splash-shields is required for bracket/caliper clearance. Minor modification to hub casting might be required, depends on year/production run.

The perfect upgrade - Metallifan - 11/17/2014
No hacking up the calipers to fit like some of the other guys. Great cost effective kit, easy install, amazing results! Comes with everything you need. I recommend these to anyone looking for the best bang for buck brake conversion you can do to your GTO. Customer service is unparalleled. Do business with Bohnman!

Must have with the front Big Brake kit - Simeon Iliev - 5/28/2014
After dreaming about a Brembo big brake kit for years, I finally stumbled upon this kit, found a good price on the calipers, and immediatelly bought it. Not only is such a kit not available directly from Brembo but it is with 4 piston calipers, is a massive improvent over the factory rear brakes, and fits inside the factory 18" wheels. In my opinion, this is the most important and the best upgrade for the money available for the GTO combined with the front big brake kit. As anyone who drives their GTO hard knows, the factory brakes are just not good enough for this very heavy car. Buying very expensive rotors and high performance brake pads would help but would also cost nearly as much as doing this complete big brake upgrade. I have now put almost two hundred miles on these brakes and have to say they are simply amazing! The stopping power is simply unmatched and I cannot imagine how they would stop if I have bigger, racing slick tires. And finally, I would like to add that for those who don't necessarily need such high performance braking, this big brake kit is worth every penny just for the visual enhancement of the car alone. The appearance of the GTO with these brakes transforms from a pretty nice looking sporty car to a serious high end, expensive sports car. I cannot think of a better appearance modification for the GTO then a gigantic pair of brembo brake calipers filling up the entire wheel. These are the brakes that the GTO should have had from the factory.
