Mach V Two-Piece Brembo Adapter Rotors 2022+ WRX

Did you manage to source some STI Brembo four-pot or six-pot front calipers? These adapter rotors are for you. Mach V Motorsports two-piece Brembo adapter rotors allow you to bolt up STI Brembo brake calipers (either four-piston or six-piston) to the front of your 2022+ Subaru WRX. Because of the suspension geometry of the front axle on the VB-chassis, the brake caliper and the corresponding rotor have moved outward compared to the older cars. That means if you try to use rotors meant for the 2021 and older STI, they will not fit. These custom two-piece front rotors solve that problem, allowing you to bolt up either four-piston or six-piston STI Brembo calipers to the front axle. Plus, they are far lighter than a single-piece cast iron rotor. The rotors use an aluminum center section for light weight. The outer ring is cast iron; high-strength fasteners join the two. Two-piece rotors reduce rotating mass, but there are other benefits, including decreased heat transfer to the hub. Once
