Detailed Product Description

This Centric C-TEK Standard Disc Brake Rotor (part number 121.33048) is a solid rotor designed specifically for Audi A4 models. The rotor features a smooth surface type that ensures even pad contact and consistent braking performance. With an outside diameter of 245 mm and a nominal thickness of 10 mm, it meets the precise specifications required for proper fitment and function. The discard thickness of 8 mm indicates the minimum thickness before replacement is necessary, helping maintain safe braking operation.

The rotor’s overall height is 83.6 mm, and it mounts using a 5-lug pattern with 14 mm diameter holes spaced on a 112 mm bolt circle diameter. This rotor is designed to mount directly to the hub, providing a secure and stable fit.
