The Chase Bays Fenderwell Caliper Brake Lines are for the enthusiast who wants to increase braking response, improve pedal feel, and upgrade to a more durable setup. The OE rubber hard lines are upgraded and replaced with -3AN stainless steel braided, Teflon PTFE lined, black PVC coated lines. We use the best components in the industry and we pressure test every line we assemble. These are DOT approved! We guarantee a leak free start up if this product is installed correctly.
Our BMW Fenderwell Lines are much more effective than any other kits on the market. The issue with BMW E46 rear brake lines is they have a multi-piece rubber line design. This creates more connections which is more labor to install and just adds nonsensical clutter. Starting from the chassis where the hard line(s) change to the stock rubber soft lines; you have about 6" of rubber soft line, then at the trailing arm it changes to hard line again, only to go back to 6" of rubber soft line which connects to the caliper.
What Chase Bays does differently is we eliminate the trailing arm hard line and second rubber soft line to create a one-piece design. It goes directly from the chassis hard line to the caliper in 2 connections instead of 4. See comparison below.
Fits the following chassis:
