I'm looking at a wheel that I like, but they only make it with a 35 or 40 offset. I'm pretty sure that 35 won't work ( I have an 05 wrx), but I'm not sure about the 40. Is anyone running wheels with an offset of 40?
The optimum offset for our subarus is usually a +48. From what I have gathered from other sites, you do not want to go more than +/-5 in either direction. So no less than a +43 and no more than a +53.
