You should invest in Function & Form coilovers. Something like $620 Brand new.
I would have gone with full coilovers. I already have koni yellows and they don't really have a great resale value. Bought the yellows brand new so I have the lifetime warranty on them…
In any case if I can't get the 18x8.5 to sit well, I'll just get a set of 18x7.5 rims instead
