15" Brake Clearance Kit — BMW E9X 335i / 330d / 335d
Choose your size below. One E9X AutoHaus Essentials Tee will be added with your kit and discounted to $0 automatically.
A rear brake clearance conversion for BMW E9X 335i, 330d and 335d models, developed specifically for performance and drag-oriented builds looking to run compatible 15-inch rear wheel setups.
The conversion replaces the relevant factory rear brake components with a matched aftermarket caliper, carrier and 300 × 20mm rotor package. The smaller brake package creates the additional barrel clearance required by compatible 15-inch wheels while retaining the factory handbrake arrangement.
Why the conversion exists
- Designed for 15-inch rear wheel setups — creates additional brake clearance for compatible 15-inch performance and drag wheels.
- Complete matched conversion — supplied with the required aftermarket caliper, carrier and rotor rather than requiring the components to be sourced individually.
- Retains the factory handbrake — the conversion is designed around the existing BMW handbrake arrangement.
- Performance and drag focused — intended for builds where a smaller-diameter rear wheel and higher-profile tyre package is required.

Wheel clearance
Important: the kit is designed to enable compatible 15-inch rear wheel setups, but clearance is not universal across all 15-inch wheels. Wheel barrel diameter and profile, offset and spoke design can affect brake clearance. Wheel fitment must be confirmed for the specific wheel and vehicle combination before ordering.
Availability & lead time
This kit is made to order and is not held as stocked inventory. Please allow approximately 3–4 weeks for the kit to be prepared before dispatch.
Performance + Drag
Developed for E9X owners building functional performance and drag wheel-and-tyre packages where the factory rear brake package prevents the intended 15-inch wheel fitment.
