I also need help, thinking of getting 18s. Currently have 17x8, 4.5bs, 0 offset on 235/45 and 245/45. Car is lowered, Streetgrip, with a 3/8" coil spacers upfront (had rubbing issues before) and including 1" lowering kit in the rear.
Would this setup be ok? It's the closest ride height setup to what I'm on now.
Front: 18x8, 4.75bs, 235/40
Rear: 18x9, 5.25bs, 275,35
Rear: 18x9.5, 5.5bs, 275/35
-any idea on offset to go with? (aim is to have deepdish style wheels).
Measurements from ground to fender:
Gap between rear tire and fender: 1.9"
