so i should feel good that there isn't even a pinky tip width between my brake caliper and my 19" oem wheels?

It's the space between the barrel and the caliper that is most critical from a performance standpoint. :)

I don't know. It all depends on your purpose. If you're building a car for Redline Time Attack and you're in the Enthusiast or Street class, the widest tire you can use is 285, so there's no point in getting a 11" width wheel. Therefore, a 10" width or maybe even 10.5" width wheel would be better in this situation. A lot of 18" wheels clear the Akebonos and even the AP Racing BBK. Go check out the Robispec 370z if you want an excellent example of a purpose-built machine. On a side note, my track wheels are 18x10 all around haha. I didn't really find the need for 19's. :tup:

why 19? bc theyre young, innocent, nieve, and can be talked into all kinds of your wife/gf won't do. wait whats this thread about?

And possibly saved yourself a fair amount of unsprung weight in the process, which was my original point. Thanks, OMGWTFBBQ (great name, BTW).

lol

So let me get this straight...

Will an 18" wheel fit on our sport package brakes?? I'm about to drop a hefty amount on some different wheels (Volks) and I would obviously like to save both $$ and unsprung weight if possible and go with an 18" if I can. (I track my car)

Enkei RPF1's and Enkei NT03+M's fit with no problem.

Another benefit of 18's over 19's is increased tire selection and cheaper prices. :tup:

Oh yeah. So do Enkei PF01's and SSR Type-F.

The reason a 19" wheel looks better than an 18 is that the wheel fills more of the wheel well, not the black tyre.

dunlop starspec's only comes in 18's. and they are the best tires according to car and driver

Cosmetics... 19's look nicer, for the z, they're actually wider so will provide a bit more grip.

on the track the 19's have a different slip angle, you need to be a better driver with the 19's...

18's benefits are: less likely to be stolen, better ride comfort (more side wall), cheaper to replace, less noisy, slightly more protection against gutter scrape and they're lighter.

Do you mean the Enkei PF-01 18" with the +38 offset--is that the one that fits over the Sport Package brakes? It's a nice looking wheel and may be a good deal lighter.

personal preference
 

I myself enjoy the look of 19's on the 370z. There is nothing wrong with 18's though. What I don't like is too big of wheels on cars, trucks, and SUV's. I just think that they need to be correctly proportioned to the vehicle.

On an extra note: The wheels and tires of the F1 car are a beautiful thing!

my point exactly, plus weight and cost :eek:
