About this kit
A complete rear big brake kit for the Audi A3 8L1, Audi A3 8P1, Audi A3 8V1 and more. It uses two genuine Audi 19Z calipers (4-piston, made by Brembo) and a pair of rotors (380–400 mm) in high-carbon steel or carbon-ceramic, plus pads, braided lines and mounting hardware.
We match the mounting brackets to your car. You'll need at least 19-inch wheels with enough room for the caliper. Not sure? Send us your wheel details.
You choose the rotor size, rotor material, pads and caliper color. Calipers come in their original finish, or in a custom color. Each rotor option comes with OEM pads or TTSPORT pads; you pick when you choose the rotor.

All Brembo kits →Common questions
Will it fit my wheels?
Big calipers need room inside the wheel. Check the minimum wheel size in the specifications. If you're not sure, send us your wheel make and size and we'll check.
Do I need new brake lines or fluid?
Braided lines come with the kit. You'll need fresh DOT 4 fluid and a full bleed after fitting.
Can I fit it myself?
If you're used to brake work and have a torque wrench, yes. If not, have a workshop fit it. Our installation page covers the basic steps and bed-in.
