Description
If you’re running a GM Metric brake system in competition, this Wilwood caliper delivers the stopping power and consistency you need when it matters most. The 2.75-inch stainless steel piston provides superior braking force while the cast iron construction handles the thermal demands of racing. It’s a direct bolt-on replacement for 1978 and later GM Metric systems, making it the go-to choice for spec racing categories where reliability can’t be compromised.
