I'm going with 18x9.5 +30 with 265/35-18's. I haven't purchased the springs yet, but I'm going with a heavier spring rate over stock (Tanabe) to counter the kind of travel that you're talking about.
Due to the offset and tiresize, I need to roll the rear fenders. I didn't want to go to a tire shop because of the 35 profile and the width of the rim - some generic places have older equipment which can damage the wheel. Hence my question about a performance shop.
If you guys know anyone local who is decent, just point me in the right direction. Thanks.
