I get a super deal on Fast wheels through work and since I need new tires, figured now's as good a time as ever for new wheels - but I'm not sure the specs they're selling me will work based on my own homework.
These are the options they have:
They're telling me
18x9 ET40 square will work, however I don't think that's right.
I'm thinking
18x9 ET30 square, perhaps with a small spacer in the rear if I want more of a flush fitment to the fender.
Anybody have any suggestions? I'm hoping I can figure something out because my cost would work out to be about $145(CAD)/wheel, for pretty light, flow-formed wheels that look half-decent.
