G35S - Replacing front stock rims with rear stock
are spacers with seperate longer studs safer than the ones with the built in studs?
Save your money, I'm running OEM 8.5" x 18" with 245/45-r18 on all four corners without spacers, no rubs. I can't even tell the fronts stick out 8mm more. I like the fact that I can rotate my tires every oil change.
i'm approaching this from a slightly different angle.
i was thinking of getting a second set of "front" rims and running them on the rear to achieve rotation ability. so, i would have 18x7.5 rims all around with 45 mm offset.
i suspect a lot of you will cry foul, that this isn't a good idea due to looks or traction, but i was wondering if there would really be all that much differnce.
i see 5mm difference in offset (the rears would not be quite as close to the outside of the fender) which is barely noticeable.
as far as traction, i think the tire design and compounds make more difference than the size.
i see more tire options in the 225/50-18 range and more affordable as well as the option of going to a 55 series tire that rides more like a grand touring tire than a sport model.
narrower tires are safer in the rain - less prone to hydroplaning.
narrower tires offer slightly improvemed mileage.
anybody see a problem with doing this? i'm going to see the dealer this weekend for an alignment and was going to price rims while there.
thanks for your input!

And to add to the thread - I've run rear 350z rims 245/45-18 on the fronts and they look/fit just fine.... well they look like sh*t, but they fit fine hahah

its all about what you are looking for.
as u stated going with 7.5 on all 4's has some benefits. i mean the XS does it right?
the only thing i can thing of is the looks of how far the wheels stick out in the rear
and thats just a personal preference thing.
if ur above stated beni's are what you are looking for then i say go for it
how much do you want for your 8.5 rears?
amp, i don't see any "problems" going ether way.

I would be very surprised if you get better gas milelage with a narrower tire. I think driving habits and tire inflation have more of an effect.
Handling is definalty not going to improve if you go with a taller all season. Each to there own.
Let us know how much the dealer wants for two OEM 18x7.5 wheels. That should be good for a chuckle.
Good luck, post some pics when your done.
Good pics so far. Do you have more shots showing both front and rear in profile, all 8.5"? If all goes well, I'll have a set of fronts (7.5"), no tires, for sale this weekend. Shoot me a pm if interested. I'll be reasonable.
Well crap. My source for a set of rear wheels fell through. The wheels were damaged in shipment and the supplier is having trouble finding a second set.
