Wilwood GT Series Big Brake short-offset hats are precision machined from premium aluminum alloys for strength with minimized weight in tight-clearance installations. This .543 in offset hat fits 5 x 4.50 patterns on a 12 on 8.75 in bolt circle and is designed to provide a stable, low-mass mounting surface for through-hole rotors, helping control pad engagement harmonics and in-service thermal variation.
