Looking at doing some track days other than drift so I'm shopping for some semi slicks. I'm currently running on 14x8 -12 rims and wondering if its beneficial going to a 15 inch rim. Namely a 15x9. Now on the 14's I would look at running a 195/60/14. The only ones available that I've found to come in this size is the Bridgestone re55s, Dunlop dz03g, Yokohama a048 and a050. I could go a 205/55/14 in a toyo r888 or nitto nt01 but I'm worried about front guard clearance.

All of the tyres I've mentioned are available in 15inch in a 195/50, 195/55 or 205/50 which would be my preferred size.

Should I go to a 15 inch wheel? Will it make that big of a difference?

Thanks guys
