I am seriously considering running Neuspeed rse10 in 18x9 et45. I would like to pair them with the new Michelin PS4S in 255/35/18.
Would these fit with stock suspension and fender screw mod? My research is saying it probably will fit, but may need a little more negative camber up front. I have also heard the PS4S runs a little narrower than the Pilot Super Sport so that may help.
Have you seen a car with a 9" wide wheel and 255 tires that isn't lowered? A better question, do you plan on lowering the car later?
You definitely won't have any issues running this setup on a stock height car, but IMO it'll definitely have a *look* to it. Without the natural camber from lowering the car and the few inches of fender gap it can look like it's poking a lot more than on a lowered car.
I think with a lowering spring and the fender screw mod you shouldn't have any issues with that setup as well. Just a bit wider tire than what I'm running, but if you went too low there could be some tire to fender issues. You might consider a narrower tire, unless you're set on that width for traction reasons.
