The Wilwood GT Series dynamic-mount rotor hat offers precision-machined aluminum construction for high strength and low unsprung weight. Featuring a 0.55 in offset and 5 x 4.72 bolt pattern on a 12 on 8.75 in circle, floating T-nuts allow dynamic mounting of through-hole rotors while the wide load-bearing surface helps isolate pad engagement harmonics and thermal shifts between hat and rotor.
