Yes,

They will fit just make sure the (offset) are within spec.

Depending on the offsets It may or may not need spacers

Keep the tire size to stock sizes IF you're not going to do anything fancy.

Only if you want to go with a wider wheel that will stick out past outside the fenders. Camber wil tilt top of the wheel, thus fitting it back flush with the fender.Lowering the car wil also have a tendency of cambering the wheels in, so if you decide to lower the car, you might want to go with wider wheels or larger spacers.

Stock 19" 370z wheels will only require an alignment at a regular old shop.

As stated above, camber kits can be used to increase negative camber when you have wide wheels that won't clear the fenders. They can also be used to decrease negative camber on lowered cars that will maintain toe/camber specs and increase tire life and straight line performance/grip.

But again, you won't need them if you're just using a stock wheel and are not lowered. Cheers.

alright guys. i need a confirmation on something.

is 3% the maximum tire diameter difference FR to RR? Will say 3.1% throw a code?

any speculation on whether or not an ECUtek tune can take care of the problem?

I'm running 275/35-19 PSS which is 26.6" and 345/30-19 PSS which is 27.2". With no issues. ;)

yea, you are teetering right on the edge which is what even gives me hope, haha.

i have this hairbrained scheme about going 19"FR and 20"rear. I also want to run some serious rubber, but so far the closest i can come in terms of diameter, and keeping sidewall more or less the same, is 3.1% difference FR>RR (285/30r19 FR | 335/25r20 RR). my preferred tire selection would actually put it at about a 3.4% difference (285/30r19 FR | 345/25r20 RR), which i expect would definitely cause weirdness. obviously a wonky traction control system makes the idea a no-go.

edit: there are other tire choices that come closer, but i was hoping to run some 325+ on the RR. however, i like the sidewalls/diameter sizes of some of the narrower options.

sound's like you're after the ZR1 wheel set up,,,could be wrong-but i was thinking that 335/25/20 only came in run-flats.
Factory Diameter setup's are 325/30/19R & 275/35/19F ,The Michelin PSS tires are probably some of the widest tread ones.
"Rusty" has that Bad-Azz look!!!
i was thinking Pro-Street look 345/30/19R & 255/40/19F MPSS on 8.5 & 12" Forgelines.
or 295/35/19F on 10"wide wheel.
PS...."Rusty" also has unlimited funds!

You are spot on. the 285/30r19 FR and 335/25r20 RR setup is with PSS ZPs (run flats) same as the C7 vettes. I am not keen on the idea of run flats, but you can't argue with the handling success of the vettes.

Last night after spending some time with tire calculators and searching TireRack I also came across an alternative 275/35r19 FR | 305/30r20 on regular PSSs that would work better (2.2% diff FR>RR) and also fill the fender wells more (i.e. larger diameter than the wider ZPs mentioned). This option wouldn't create any problems with the TCS, but I lose width in the rear. It also has the advantage of being the same width as RS3 tires I will run as track tires.

So the 275/305 setup is currently my top choice if i decide to go 19/20. I expect the narrower rear tire won't have a major impact on traction. So, the only thing I lose is my spot in the "370z Wide Tire Hall of Fame", next to Rusty. :roflpuke2:

Would you want almost 1" difference in diameter of these tires; seems that it would mess up your abs. & everything else.Attachment 106160Attachment 106161

Not sure the reasoning behind the 19/20 wheels... Corvettes are set up for it. With 1" shorter tires in front/ sidewall is the same.
If you want big- go 345/30/19R & 295/35/19F or if you like the 20's & handling; go 325/25/20R & 265/30/20F both 26.3"diameter. Won't affect sensors & potentially handle better than vette! Just my 2cents. :)

Thanks for all the input. The problem with the traction control/ABS is the reason I originally posted. I am 99.9999% sure the corvette setup would throw a code. Seems the max difference FR>RR that the car will handle without a code is 3%, and the Vette setup is 3.5% difference. I assume Chevy simply set the ECU to work with this setup. Which is why I was wondering if an ECUtek tune might be able to avoid the codes (the most recent rom has control of the traction and abs systems).

I´ve been thinking I would go the 20" route for a while and the 265/325 tire setup you mentioned is where I´d settled.

The thing is, and this is all a matter of personal taste. 19s look perfect up front, but they look lost in the rear and vice versa for the 20s (perfect in the rear and huge in the front). Our cars have a relatively slim nose and a super tall rear, similar to the C7 vette (which is why I assume the Vette runs them in 19-20 configuration).

IF I decide to go 19-20 I think I would be just fine with the 275-305 setup. the 275/35 on the front is real close to stock diameter and a little more meat in the back wouldn´t hurt anything. Sidewalls are really close in size.

Either way, thanks again for throwing down your opinions/advice.

You right about that; what ever tickles your Fancy! If you like it/that's all that matters.
I said earlier that I like the pro-street look 345/30 & 255/40 on 19's Michelin PSS,8.5 & 12" wheels...27.1,2ish diameter. That's what I like & haven't seen another one yet.
The Z06 look would be different with having the front low....I just don't have the Greenbax right now.Attachment 106175

I Like My ~Z~ Better!

i think i will ask cooltoy to chop this one up for me. give a better idea of how it might look.

to the batcave!
