Will 5x100 to 5x114.3 wheel adapters (hub-centric, 15-25 mm) fit a Subaru WRX (GD/GG, 2002-2007)?

Q: Will 5x100 to 5x114.3 wheel adapters (hub-centric, 15-25 mm) fit a Subaru WRX (GD/GG, 2002-2007)?

Yes, with extra parts or work. Bolt-on 5x100 to 5x114.3 adapters are sold for the 2002-14 WRX, so 5x114.3 wheels (for example 2005-07 STI wheels) can go on a GD without changing hubs. They are hub-centric on the 56.1 mm Subaru hub and use M12x1.25 hardware, and they space the wheel out by their own thickness (15, 20 or 25 mm), which effectively lowers the wheel offset by that amount, so check fender and tire clearance. With thin (15 mm) adapters the factory studs usually poke out past the adapter face, so the wheel must have clearance pockets on its back side (one retailer says most STI wheels do) or the studs must be dealt with. A guide site points out the trade-off: the wheel load now passes through two bolted joints, the bearing is loaded further outboard, and both sets of nuts must be torqued and re-checked; cheap non-hub-centric adapters are a bad idea on a turbo AWD daily. The OEM alternative is the 2005-07 STI hub conversion. Retailer and guide sources only, safety-critical, so tier 2.
