Rear 330 Big Rotor Kit for most Subaru vehicles introduced from the Levorg onward with an electric parking brake, excluding Legacy BM/BR. Stated applications include VMG/VM4/VAG, Legacy BS/BN, Forester and newer Impreza models with the latest electronic parking brake.
Manufacturer prices: 1P rotor kit JPY 168,000 excluding tax; 2P rotor kit JPY 188,000 excluding tax. Each kit includes two dedicated support brackets, two eight-slot rotors of the selected one-piece or two-piece type, and two brake-hose relocation stays. The one-piece version ends when those rotors are depleted.
Dedicated replacement-type supports and rotors increase diameter from the factory 300 mm to 330 mm while retaining 17 mm thickness for the factory calipers. The two-piece rotor is approximately 500 g lighter than the factory rotor. The kit improves rear braking and the visual balance with large front calipers, and is also recommended by the supplier for factory-front-caliper users concerned about nose dive.
The replacement supports retain the factory number of bolted joints, avoiding extra mounting joints and hardware that would increase unsprung weight. Two-piece bells are bronze-colored; one-piece hats are black with decorative imitation mounting bolts. Supports have four additional machined holes for the optional finisher cover and a silver nickel-chrome plated surface.
Manufacturer replacement-part prices: one-piece rotor left/right set JPY 58,000; two-piece rotor assembly left/right set JPY 79,000 excluding tax (as stated in the source).
Optional caliper finisher covers include K2GEAR logo stickers and fasten using four hex nuts. They fit this K2GEAR Rear 330 Big Rotor Kit only. FRP, unpainted: manufacturer price JPY 18,000; separate painting JPY 18,000, tax status not stated.
