Racing Line’s Stage 2 Performance Rear Disc/Rotor upgrade is the perfect upgrade to match any Racing Line front Big Brake Kit. A pair of high quality, direct replacement rear vented rotors that are a simple swap for your factory originals. They make the perfect upgrade to complement either a Racing Line Stage 2 or 3 Big Brake Kit, or of course any other braking hardware. The 310mm x 22mm single-piece discs are manufactured with the same ‘Triple Groove’ design as the Racing Line front BBK rotors use across the face for improved bite and debris clearance, making these rear rotors a perfect match in both performance and appearance. The one-piece rotor itself is made from high cast carbon - a mixture of high quality steel combined with carbon, giving a far higher friction coefficient compared to normal steel rotors. To protect them, Cerakote ceramic high temperature coating in black is used for the centre bell and outer lip to provide thermal protection and ensure corrosion resistance for many years. Get rid of those rusty factory hubs forever more! Fitment is simple: they are a direct replacement for factory ventilated rear discs/rotors of 310mm x 22mmsize. Note that for cars with smaller non ventilated 300x 12mm rear rotors, an OE caliper upgrade to the larger size would be needed before fitment of these discs. Compatible with all brands and compounds of brake pads.
