The kit includes vented, cross-drilled, and slotted rotors measuring 11 inches (279.4 mm) in diameter, engineered to keep brakes cool and reduce fade under intense driving conditions. Featuring a four-piston caliper design, the system uses BP-10 friction brake pads which provide strong, reliable braking performance.
Perfectly tailored for GM 8.875 inch (12-bolt) passenger car differential cases with a 10/12 bolt Chevrolet axle flange style, this rear parking brake kit provides an internal drum parking brake provision built right into the design. It supports triple 5-bolt rotor patterns including 5 x 114.30mm, 5 x 120.65mm, and 5 x 127.00mm bolt patterns, making it a versatile upgrade.
Note that the kit is sold with all rear components including rotor, caliper, and pads, but does not include front rotors, calipers, master cylinder, brake booster, or hoses. It requires C-clip axles only and does not support special end or C-clip eliminator modifications. If installing on a 10-bolt differential, the Wilwood 300-11532 register ring is needed.
Designed for wheels with a minimum diameter of 14 inches and an offset of 2.75 inches, this kit ensures compatibility with many custom builds and hot rods. Installation and performance support reflect Tuningsupply's commitment to enthusiast-driven service and fast, reliable delivery across Europe.
Choose the WIL Dynapro Brake Kit for a top-quality, track-ready rear braking upgrade that combines engineering precision with aggressive style.

Called for a part that was not in the assortment, but was available from one of their partners. Product could be ordered without difficulty and was delivered quickly. Very nice communication, thank you!

Had the parts that I could really only find elsewhere on the internet via an awkward import promotion from either the UK or the US. Tuningsupply had them on the website, at a good price and they were also delivered quickly. So good service!

So cheap!!! At first it was really a gamble for me to order my rims from Tuningsupply because they were so very much cheaper than elsewhere. And sure enough, on the ninth day DPD arrived at the door with my rims. Really a total of 360 euros cheaper!!!! For me a very big applause for this company.
