17x9 vs 17x8 vs 18x8 - Page 2 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

I still vote 17x8 with a 235 tire. 245 or 255 would be better suited for a 17x9. Personal opinion only. There are guys in the aggressive wheel fitment thread that are putting 215s on 18x10's. But they're not looking for performance, either. They're looking for stance.

Im looking for 100% performance, dont really care for form. A stretched tire was never bad, Porsche tires are quite stretched from the factory for example..

gramicci101 · 10-21-2014, 03:09 PM

In that case I would go 17x8/225 or 17x9/245. @ATL BRZ runs 17x9's with 245 tires on his NA track car; you should check out his build thread. Granted, he runs E85 and has the suspension to support tires that wide.

Edit: thread

The rule of thumb for performance is that the tire tread width be +/- 1" of the wheel width, and generally that along that continuum a narrower tire will offer more precise handling and response.

17x9 with a 245/40/17 sounds like what you want.

Highly disagree. 17x9 *can* fit stock suspension.

17x8 is a way better starting point. Start with a 17x8 and 225 tire. See how it is. Worst case scenario you don't like it and can use it as your DD setup and move on.

If you don't like 17x9 worst case scenario is you have to buy aftermarket suspension to fit the tire size you want. And all the issues related to getting aftermarket alignment adjustment parts.

The setup I just described DOES fit stock suspension. with a 45 you need a small spacer...5mm is probably ideal.

Budget is relevant to have for starters

Weds sport tc105n 17X9 +35... IIRC, they are discontinued.

These are light weight like RPF1, but IMO look better. (they cost more too)

They have a new wheel that looks almost exactly the same though... Weds tc105x. I think they are stronger...
