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.
