I'm looking to get 17x9.5 zr1 wheels all around or a forgestar f14 lightweight 18x9 wheel all around I like the 18x9 and there light weight about 18 lbs zr1 are about 21lbs I think stock irocs are 22lbs so performance won't hurt that much compared to stock

My question is performance is there a big difference to you third gen people that drive there car hard on track and street with 35 vs 40 series tire ?

I'm in California and roads are crap here lol and I drive my car hard I really don't baby my car around town and drive on fwy a lot too worried about 35s and lightweight rim and pothole = bad day

I know 40 series tire for 17s would fit but with 18s I can run either 35 or 40 series tire.
