About this kit
A complete front big brake kit. It uses two genuine Mercedes-AMG GT63 calipers (6-piston, made by Brembo) and a pair of two-piece rotors (420 mm), plus pads, braided lines and mounting hardware.
It bolts onto the factory caliper mounts, so there are no adapter brackets to fit. Tell us your car when you order and we'll confirm it fits before we build the kit. You'll need at least 21-inch wheels with enough room for the caliper. Not sure? Send us your wheel details.
You choose the caliper color. Calipers come in their original finish, or in a custom color.
The price depends on your car and the options you pick. Request a quote and we'll email you a price. Built to order; it ships in about 15 business days.

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.
