GrimmSpeed 5x100 and 5x114.3 3mm Wheel Spacer (Pair) - Subaru WRX/STI
GrimmSpeed builds this 3mm wheel spacer pair with the same fit, function and long term reliability focus they apply to every component they make. It's a simple, no gimmicks solution for anyone running a Subaru WRX or STI who needs a touch more clearance for suspension components or wants the wheels sitting closer to the fender.
This listing covers 5x100 bolt pattern applications including the WRX GC8, GDA/GGA, GE8/GH8, GF8 and GV8/GR8, plus the 2004 STI (GDB). The dual-drilled design also covers 5x114.3 applications including the STI GDB, GRF/GVF and VAB, the 2015+ WRX VAG, and the 2022+ WRX VBH.
Note: Confirm your vehicle's bolt pattern before ordering. This single pair is dual-drilled to suit both 5x100 and 5x114.3 hubs, so fitment depends on your model and year rather than the spacer itself.
