Give your E83 the stopping power it deserves with TAROX rear rotors engineered for the 320 mm rear axle configuration. This is a direct fit replacement that transforms pedal feel, reduces fade and delivers confident braking on fast road and track day use. Ideal for drivers searching for BMW X3 rear brake upgrade, slotted rear discs, drilled and grooved rotors, performance rear brake discs and OE-spec replacement rotors.

Why choose TAROX for your E83

• Vented construction for efficient heat management and consistent performance under repeated heavy braking.
• OE-spec castings that undergo multiple heat treatment stages to relieve internal stresses for strength and stability.
• Precision CNC machining followed by individual surface grinding to an ultra-tight tolerance approaching 0.015 mm, giving an exceptionally smooth, even braking face and superb modulation.
• Hand finished by skilled operators for a premium contact surface that helps reduce judder and improves pad bedding.
• Developed from decades of Italian braking know-how dating back to the early 80s.

Choose your braking surface

• G88 pattern - multiple radial slots create a turbine-style effect that moves hot gases away from the pad face. Helps the disc run cooler and reduces the risk of warping, vibration or cracking. A favourite for spirited road driving and hard use.
• F2000 pattern - curved grooves that deglaze pads and balance cooling with strength. The go-to for drivers who mix daily use with serious circuit sessions.
• Sport Japan pattern - fully drilled, countersunk holes plus six grooves for aggressive bite and effective gas evacuation. One of the few aftermarket options to feature true through-drilling for fade resistance and sharp response.

Many applications are produced from TÜV approved castings and numerous fitments carry TÜV or ABE recognition. TAROX Corsa and road compound pads pair brilliantly with these heat treated discs for maximum bite and stability.
