So I've got a set of 18x9.5 wheels with a +35mm offset that I'm looking to throw on. I've done enough math and checking to see I should be okay there, but also, I'm thinking of going wide... really wide. I've seen some people say they've done 295s with stock widened wheels, and I think I can get away with 315s with the different offset. I've seen some people mention that 305s are doable even with stock offset, but that if you drop it any, you either need to cut into the shock cover or get smaller rear shocks. If lowering does affect the rear width clearance, I'm thinking I should drop first then switch wheels.

Any advice would be great, thanks!
