TAROX Sport Japan Rear Brake Discs/Rotors Pair 324mm (324x32) for BMW 1 Series E82 135i Coupe 2007-2013 - Vented Cross-Drilled & Grooved Slotted - ATE Compatible OE Replacement Performance Upgrade - 5505-SJ

BMW 135i E82 Rear Rotors - Sport Japan Pattern 324x32 - TAROX 5505-SJ

Give your BMW 1 Series 135i the stopping confidence it deserves with a premium pair of rear rotors from TAROX. The Sport Japan pattern combines countersunk cross drilling with six precision grooves to deliver stronger initial bite, fast heat management and consistent pedal feel on fast road and track day driving. Part number 5505-SJ.

Designed around the original ATE rear braking system, these 324 mm vented rotors are a straight swap on the back axle. Each casting is meticulously CNC machined, stress relieved with heat treatment and hand finished for an ultra-smooth, true running surface. The drilled holes evacuate gases and dust, while the slots continually refresh the pad face to resist glazing and reduce fade under repeated hard stops.

Why enthusiasts choose this rear rotor upgrade

• Real-world performance on fast road and track sessions with sharper bite and dependable deceleration
• Cross-drilled and grooved layout for rapid heat dissipation and fade resistance
• Vented rear rotor pair engineered to OE geometry for a hassle-free bolt-on fit
• Precision machined and individually ground for a smooth, quiet contact patch
• Durable castings treated for strength to handle repeated high-energy stops

We run these Sport Japan rears on customer 135i builds and the feedback is consistently positive - stronger pedal response, repeatable performance lap after lap and real confidence on B-roads.
