Description
If you’re running in IMCA-sanctioned competition, you need a caliper that meets tech inspections while delivering consistent, repeatable braking performance under race conditions. The Wilwood GM Metric Race Caliper combines proven cast iron construction with a large-diameter stainless steel piston to give you the stopping power and durability required across Modified, Stock Car, Hobby Stock, and Sport Mod classes. This is a purpose-built racing component—not a street brake adapted for the track—engineered to handle the thermal cycling and repeated hard stops that define competitive racing.
