Wilwood Hat-BB Rear 1.75in Offset 5 x 4.50/4.75 - 12 on 8.75in

This is a Wilwood GT Series Big Brake flared bell rear rotor hat. It's precision machined from aluminum alloys, which means it's strong but also keeps weight down. This hat is designed to work with standard through-hole mount rotors, using threaded holes for the rotor mounting bolts. You can also use it with special slotted rotors if you have the right hardware kits. These hats are typically used for rotor bolt circles of 8.38 inches and larger, with offsets ranging from 1.88 to 3.00 inches for rotors 12.19 inches and up.

The flared bell design is a key feature, offering a solid and reliable mounting point for your brake rotors. Wilwood hats are well-built and are a popular choice when you're upgrading your braking system and need a strong foundation for your rotors. This specific hat has a 1.75-inch offset and fits bolt patterns of 5 x 4.50 and 5 x 4.75 inches, with a rotor mount of 12 on 8.75 inches.
