Tarox BMW E82 135i 324mm Sport Japan Drilled and Slotted Rear Brake Discs
Upgrade the stopping power on your BMW 1 Series E82 135i with TAROX Sport Japan 324 mm rear brake discs, part number 5505-SJ. These performance rear brake discs are a direct-fit replacement for the BMW 135i and are engineered for fast road and track day use. With fully drilled countersunk holes and six precision slots, these vented rear rotors deliver stronger bite, faster heat dissipation and exceptional resistance to brake fade.
Originally designed for the demanding Japanese performance market, TAROX Sport Japan discs combine tough looks with proven performance. Unlike dimpled alternatives, the fully drilled countersunk design effectively vents gases and dust to keep temperatures in check, while the six grooves continually refresh the pad surface to prevent glazing and maintain consistent braking. Every disc is based on OE specification, machined to ultra-tight tolerances, heat-treated for strength and hand-finished for a perfectly smooth braking surface. Most applications in the Sport Japan range are TÜV approved.
