My wheel and tire setup - need expert advise.

DannyGT

So my setup should rock then!! I never mentioned spacers nor would I use them to widen the track. I just wanted to make sure the setup I originally mentioned would be a suitable street/track setup.

EDIT: I would like to add tho that the +40 offset I originally mentioned has been discontinued on the particular wheel I was looking into. I can only get it in +22 now in the front.

19x9.5 +22F
19x10.5 +22B

Those are the new specs. No spacers. That should outperform the stock setup with with all the mods I spoke about earlier, correct?

I don't think it will make much of a noticeable difference.

I have a question:
the new 370z rear tire size comes in 275/35WR/19's.
Later on I would like to change them to Nitto INVO tires, but the closest
size they have is 285/35/19, or 285/30/19. Any problems you see with
either one?

thanks.

i think the front tire set up of 275 is to wide. Won't that hurt the performance of the car? If you look at the lambo and other exotics there tire set up for the front isn't that wide usually.

Lambos and other exotics are usually mid-engine cars with more weight over the back than the front so much less tire is needed. Skinnier tires up front is also the factory's way of dialing in understeer to vehicles for safety purposes.

I run a 295 up front on the time attack 350Z, and will be running a 275 up front on my track setup for the 370Z. Going with a wider front tire will hurt the vehicle's turn-in and straight line speed with the added weight and rolling resistance, but what it gains in corner entry and mid corner speed usually far outweighs the losses.

Ah I get it. Thanks for the info.
Just curious what size are you going to use for the rear tires? since it's a front engine, other than for better cornering, more weight and what not is there a bad thing going wider on the rear for the 370?
Going 270 up front will you need spacers?

No you will still need bigger tires in the rear, just usually not as big of a difference between front and rear as say a mid or rear engine car.

Because of the time attack class I am running the car in I am limited to a 285 max width tire. If I wasn't limited I would probably do a 305 in the back and probably no more than a 20mm difference between the front and rear.

DD,

What is the widest tire you would recommend for a 10" rim ?(rear) Could I get away with a 305/30/19 ?? (Stock sport rim with 5mm spacer)
I really would like to try a set of the Nitto Invo's, I wanted to go with a 295/30/19, but they don't make this size. seams pointless to only go to a 285.
