Tarox Rear 350mm Brake Kit - Super Sport - 3 Series (F30/31) All models Excl. M3

Transform the stopping performance of your BMW F30/F31 with a proven rear big brake upgrade engineered for serious road and track use.

This premium Italian-built system delivers confidence, control and consistency on every drive. Hand finished in small batches and tailored to the BMW F3x platform, it combines lightweight two-piece rotors with a robust multi-piston caliper for powerful, stable braking and a firm, reassuring pedal feel. We have installed this setup on customer cars and our own demonstrators, and the feedback has been outstanding for pedal modulation, fade resistance and overall stopping power.

Fits BMW 3 Series F30 Saloon and F31 Touring, all petrol and diesel variants including xDrive, excluding M3. Minimum wheel size: 18 inch.
