Brand: Wilwood Engineering
Spec-37 rotors from Wilwood are cast from a proprietary iron alloy, with heavy walls to reduce warping and cracking due to heat stresses.
The GT 72 disc measures 11" OD x 0.81" thick, with a 6 x 6.25" bolt circle for attachment to your hat (not included). The friction surface ID is 7.42", and the bolt lug ID is 5.59". Straight (radial) cooling vanes are non-directional, so these rotors can fit either side of the car. The unique GT Series asymmetric slot pattern has been developed for optimal brake pad conditioning and cooling. Each rotor is individually balanced at the factory.
Sold individually. Brake hat and attachment hardware are not included.
