GB: Rota Wheels v2

[Inn-Tune]

true true. sorry to sound like a noob, but what i’m asking is that half inch going to make a noticeable difference if i decide to auto-x a couple times next season? also, what is the cost difference between the two?

I think it makes a noticeable difference if you go up in tire width, so yes.
15X6.5 slipstream is 375/set
15X7 slipstream is 412/set
