Liberty and Impreza Wheels
FACTORY PCD: 5x100mm
FACTORY OFFSET: +55mm*
* WRX from 97 on is +53mm and the STi 22B, Forester and Outback use +48mm
Continuing the tradition of choosing unpopular stud patterns Subaru suceeded again when designing the Liberty and Impreza (and the variants Forester and Outback) While not as right-wing as the MY and L-Series stud patterns, the 5x100mm PCD is only shared by some Audis, Toyota Celicas and Camrys amongst few others.
On the upside, there is a greater availability of wheels to suit these models in both aftermarket and OE form. From the factory the different sizes of wheels available were 14x5.5", 15x6" (the two most common) and some models had 16x6.5" (Outback and some Heritage), 16x7" (WRX), and even 17x8.5" (some STi 2.2L coupes and 22Bs, like you'll be seeing a lot of these at the wreckers 
).
