Wilwood Grand National Six Piston Brake Caliper
Wilwood’s GN lll is a time proven caliper that has been widely used with 5 on 5 hubs for stock car, road course, and off-road competition. The 6.00" mount configuration (also available in 3.50” mount) incorporates this legacy of enduring performance, with options available for the latest brake system heat management technology.
The new generation GN lll uses the same popular 6.00" mounting pattern found on earlier GN caliper series. Te GN lll can be run with either a 1.25" or 1.38" thick rotor.
