GrimmSpeed 5x100 Wheel Spacer Kit - Subaru WRX up to 2014 / STI 2004
GrimmSpeed builds its wheel spacers around a hub-centric design, so your Subaru WRX or STI keeps the precise centring it was engineered with while you gain the clearance needed for a wider stance or bigger brakes. Each spacer is CNC machined from 6061-T6 aluminium and finished in Type 2 black anodising for long term corrosion resistance.
This listing covers WRX models up to 2014 (GC8, GDA/GGA, GE8/GH8, GF8, GV8/GR8) and the 2004 STI (GDB), along with any other Subaru fitted with a 5x100 bolt pattern. The kit is available in 15mm, 20mm and 25mm thicknesses via the variant selector on this page — SKU GRM.1188.1.0 for the 15mm option shown here.
Note: the 15mm spacer is not compatible with factory Subaru wheels, as the stud length doesn't clear the wheel's pocketed area. Many aftermarket wheels do clear it, but check before ordering.
