Wide, Square, Track Setups

milmast · 03-11-2021, 06:59 AM

Looking to find more info square wheel and tire setups for the track. I have a set of 18x10.5+25 Enkei RS05RRs with 285/35R18 Hankook RS4s, and they're decent on the track. I want something a bit grippier. My car is a mix of a street & track car, so ideally I'd like for the tires to be street legal (AR1, NT01, RE71, A052, etc). I don't love how the 285s have a bit of stretch on them, and was wondering what other guys are running for tire specs (pics are encouraged!). I'd like to keep the setup square so I can rotate, and ideally I'd like to not roll/pull my fenders to make more room. I'm wondering if I can bump it up to 305 or 315s without rubbing on anything. Also, does anyone track their car on anything wider than 285s? Do you like it? Would you go smaller if you could do it again?

Here's my Z:

He’s now on 315 squared.

That's sweet! Thanks for the redirect. That's what I want to run on my Z as well 🙌

315 square is easy unless you want to go super low. Anything wider though, you're going to need to do some fender work to make it fit.

I just wasn't sure if the wheel specs needed to be a bit more aggressive (or run a tiny spacer) for the fronts to prevent the tire from touching the spindle. 315 should be more than enough for now lol
