Brake Caliper Adapter, front axle, for VAG models (Audi A6 C5 4B, Audi S4 8D B5), for conversion to the TTRS brake calipers paired with Audi A4 brake discs (345x30mm, 5×112 bolt circle).

• Directly fits the listed models, allowing for easy restoration to the original condition
• No need for welding, milling, or sending your original parts—our EPYTEC brake caliper adapters ensure a smooth installation process

Required components:

• Brake calipers: Original TTRS, left caliper part number: 8J0 615 107 / right caliper part number: 8J0 615 108
• Brake pads: Reference number: J0 698 151 E

Tips, information, and advice:

• For better ventilation of the brake system, we recommend removing the anchor plates or brake dust covers.
• To assist with the mounting of rims, consider purchasing two of our wheel mounting aids >>go directly to the product here<<
• Rim size compatibility: We cannot give a definitive answer as to which rim sizes are compatible after the brake conversion. There are simply too many different rim types. However, we have developed a template to help check whether the brake system fits under your rims. If they don’t fit, you can use wheel spacers >>Go directly to customized wheel spacers<<
• After installation, check if new brake lines are needed, as the original ones may be too short or the connection may not fit. For better efficiency, we recommend switching to steel braided lines. Use our steel braided line configurator to customize and install the brake lines according to your needs >>Go to the steel braided brake line configurator<<

Please note: Our products are designed for racing and motorsport. Use on public roads typically requires individual approval according to § 21 StVZO by a certified expert. We provide an expert opinion or material certificate if needed for approval.
