If your B5 S4 is packing some extra power, make sure you have the braking capacity to rein it in. ECS Tuning offers an effective but economical rear big brake upgrade kit.

Featuring ECS-designed drilled & slotted two-piece rotors, this kit utilizes your stock brake caliper using a special caliper bracket. The bigger rotor means more leverage for more braking torque, while the lightweight two-piece drilled and slotted rotors keep thermal gain in check.

A perfect compliment to your ECS front big brake kit, this upgrade installs easily with hand tools. Check out our install PDF.

Kit includes:

• ECS 2-Piece 12.1" Rotors
• ECS Stainless Steel "Exact-Fit" Brake Lines
• ECS Rear Relocation Bracket
• Super DOT4 Brake Fluid
• Installation Hardware
