Uprated rear braking for BMW 6 Series 630Ci E63 and E64, 320 mm vented

Step up your stopping power with premium rear axle discs engineered by TAROX. Designed to replace the factory rear stoppers on the BMW 6 Series 630Ci E63 and E64 with the 320 mm fitment, these vented performance discs deliver stronger bite, cooler running and reduced fade for fast road and track day use.

Built from OE-spec castings and finished to exceptionally tight tolerances, TAROX rear discs offer a direct fit upgrade that transforms confidence behind the wheel. Expect crisp pedal response, stable high-speed braking and improved resistance to judder and warping.

Why enthusiasts choose TAROX

• Precision ground braking faces to a tolerance approaching 0.015 mm for ultra-smooth contact
• Heat treated after each machining stage for strength and durability under repeated heavy stops
• CNC machined for perfect balance and consistent performance
• Vented 320 mm rear discs that dissipate heat efficiently and combat fade
• Based on original equipment specification castings that maintain a direct bolt-on fit
• Quality you can see with the trademark hand-finished shine

Choose your braking surface

Select the pattern that matches your driving style and conditions.

• G88 grooved: Multiple radial slots create a turbine effect that moves hot gases away from the pads, helping the discs run cooler and reducing the risk of vibration, cracking or warping. Ideal for fast road and spirited use.
• F2000 curved groove: Curved slotting deglazes pads and balances heat management with strength. A superb all-round choice for cars that see both daily duties and serious track sessions.
• Sport Japan drilled and grooved: Fully drilled, countersunk holes vent gases that cause fade, while six surface grooves keep pads fresh. Aggressive look, confident feel and excellent gas evacuation.

TAROX discs are produced from TUV approved castings, heat treated for strength and hand finished for the smoothest braking surface. Many applications are TUV and ABE approved by the German KBA.
