Unlock better launches and more consistent track performance with our ZZPerformance ATS-V/CTS 15" Rear Wheel Conversion Brake Kit. Designed specifically for drag racers, this kit allows you to ditch the factory rear brake setup that only allows you to run down to a 17" wheel and instead run a 15" rear wheel package which gives you the ability to run a tire with a taller sidewall. The result? Improved traction, better weight transfer, and more consistent launches off the line.
Unlike many budget options, ZZP doesn’t cut corners. Our kit features a high-performance monoblock caliper, offering increased rigidity, improved pedal feel, and better braking consistency compared to traditional OEM cast sliding calipers. Best of all, this is one of the most affordable 15" conversion kits on the market, making it the perfect solution for racers who want serious performance gains without overspending.
Installation note: Slight trimming of the stock dust shields is needed.
