If you’re someone who regularly partakes in autocross challenges and road racing events, and hasn’t been taking advantages of the brake systems currently available in the aftermarket, then you should seriously consider the GN6R six-piston calipers from Willwood.
They’re available for most, if not, all musclecar applications and feature various options that take the outgoing GN III calipers to the next level. The six-piston design, working in unison of the latest technological attributes in the brake market make it a viable, reliable option.
Official Release:
Wilwood Engineering’s New GN6R Forged Aluminum Racing Caliper
Wilwood’s Grand National GN6R six piston radial mount calipers combine state-of-the-art design, materials, and manufacturing technology to replace the iconic GN III lug mount calipers. The forged aluminum radial mount body, bolt-in center bridge support, and radial bracket attachment system bring ultimate rigidity and accuracy to this model series.
The direct replacement model uses the same type 7520 (20mm) thick brake pads as with earlier models. An additional new model accommodates a thicker type 7525 (25mm) thick pad. Both calipers accommodate rotors of 1.25” or 1.38” thickness in diameters from 12.19” to 13.06”.
Base GN6R calipers are hard anodized finish with stainless steel pistons, and GN6R/ST Quick-Silver models feature a high-durability nickel finish with Thermlock pistons for maximum performance in sustained high-heat competition.
M.S.R.P. starts at $449.94.
