Max tire width from front to the rear.

[nsxtasy]

So after weeks and weeks of searching, the only rims in 17/18 that I really love are the Wedssports SA60M.
The only sizes I could do would be

17x7.5+48
18x10+36

I know I'd have to run a 15mm or 20mm spacer up front. Other than that, do you foresee any other issues. If I did these rims, I could run the new ADVAN Neova AD08 R tires I love in
Fronts - 215/40/70
Rears - 285/30/18 or 295/30/18

You could run into some understeer issues with that large a stagger (difference in width, front vs rear). I'd stick with 265/35-18 rears along with the 215/40-17 fronts.

Good suggestion. Do you see any issues with the 17x7.5 +48 on fronts with a 15-20mm spacer?

I think a 10mm spacer is all you'd need. 15 maybe, 20 will cause you problems.

Thanks.

Any issues (except fronts possibly rubbing at full lock) with running
Fronts 235/40/17
Rears 285 or 295/30/18

Oh, and if I did the 235 up front, I'd have to use a different rim than I want. I've spent the last 12 hours looking for ones I like.
The only ones that I'd do would be
17x9
18x10 or 18x10.5

Seems like there's quite a bit of extreme performance tire options in this setup. If it makes any difference, just re-tuned my car yesterday, made 619rwhp, but cut it down to 612rwhp and left it there.

Yes you will have issues without wide fenders. You can't do a 17x9. 17x8, 215 maximum up front with no rubbing. What has been recommended like 500 times on this forum. You can change the fenders... but I wouldn't worry about the stagger difference. You aren't tracking the car, and even if you were, you can overcome that stagger difference with suspension changes. The stagger in some cars is way more than what we are talking about here and they are compensated by suspension changes. In street driving it is a non-issue IMO

 

[bonhamsurf]

Thank you. I'm happy to hear you say ignore the stagger difference.
This means I can do the rims I really wanted the most which are
17x7.5 fronts and 18/10 rears
And tires
215/40/17 fronts
285/30/18 or 295/30/18 rears.

Can't wait to see your car finished I love it already . I need to get fatter tires too , I love the look of them . I also want to run 285s minimum in the back. Probably going to put spacers back there too , my car MUST have a nice Eva Mendez rear !
