Currently building an LS1 1995 Miata and I been thinking about a staggered setup? How much roll is required for the rear fenders? I’m thinking about the following setup. Any advice?


15x8 front with Toyo R1R 205/50/15
15x9 rear with Toyo R1R 225/45/15

 

Staggering only makes sense when you need to go super wide in the rear for big power drag slicks and can't fit fronts that are as wide. Unless it's literally just a drag car. You'd be better off with 15x9 225/45/15 front and rear. I'm sure the info is out there on what roll is required, but you'd need to know the offset to be sure.

 

what about 245s out back and 225s up front? I assume you want to stagger for traction, yeah? I also don't disagree with acedeuce802

 

Tire clearance depends on offset. Presumably you're running +30 to +35 offset in which case only a little roll is needed in rear. With that power most here, including me, would suggest 245/40 on 15x10's all around and just run flares. It's like a Cobra now, go big.
