Appreciate some opinions. Looking to put a set of BBS RI-A with some PS4s. Wheels are 18x7.5J ET48 and tires are PS4 225/40ZR18. I know 205 fits but some threads _seem_ to suggest 225 may fit on stock suspension. Car is lowered on KWv2 though. I have a set of 10mm spacers I can use.

Any thoughts on whether I should stay away?

 

ET 48 they begin at and +10 mm spacers make them now ET 38. The car is designed with ET 54. You will then have Positive Scrub radius on a front wheel drive car. It will drive like *** and brake horribly under emergency braking. It might look cool though. Whatever that means. Also, it will FEEL tighter handling because the wheels will fight your grip and turning ability. That's not fun.

This car is the WORST POSSIBLE car to outfit road tires on. On a track? It does not matter if you got up to ET 40 as Neuspeed has wheels that do that and they race cars. Remember, racing has lot less demands and safety concerns vs road use.
