Most Lightweight setup
 

I've been looking up specs for different wheels and the amount of wheel and tire combinations are overwhelming. I have found some lightweight wheels but with a twin turbo upgrade in the future should I sacrifice weight for width and traction. What would be the best balance for a good handling car that will be racing a couple of times a month. This will be a racing setup so comp tires are necessary.

check out ssr wheels... they have good lightweight wheels...

SSR Wheels

Enkei RPF1s are one of the popular, light track wheels and pretty inexpensive to boot. Seems like SSRs are moving to a more botique marketing strategy once Tire Rack stopped selling them. They are quite expensive now. With a TT setup and tracking, I'd trade off a little weight for strength. I think the RPF1s are a solid choice all around though.

RE30's are pretty light weight.

:iagree:

I'd go with a set of forged 1-piece Volks (TE37/CE28n/RE30) in 18".

TE37's are bit heavier than the RE30's. Dunno about the CE28's.

I run SSR Type-F 19's, 2pc. forged.
They are about 4.5 lbs. lighter per wheel than stock and .5" wider.

My setup. (Not my picture, but these are the same size as mine)

Just curious, but has anyone contemplated 17" wheels?

Yes, I realize that the overall diameter is going to probably wind up a bit smaller without an insanely high profile... eh, that'll just raise the final gear a bit.

Too small? Would it even fit over the brakes?

I think the CE28n's are the lightest Volk rim.

18" is probably the smallest with stock BBK.

What offset would be needed to clear the Akebono's in 18's?

even if you found some that fit, chances are a 17" wouldn't allow the brakes to cool properly. same with the R35, comes with 20's, some teams run 19's but a few 18's fit but not recommended unless you have major body mods with brake cooling ducts like a FIA race car

Ah, okay... I thought that might be the case. Lightweight 18's it is then.

Oh, what's our bolt pattern?

CE28n's are the lightest and as light as TE37-superlap's in the same size/offset but much cheaper than the superlap TE's. but that superlap finish is about worth the extra $$$ imo.

I had a set of 19x8 19x9 RE30's were 21/23 pounds IIRC
"The RE30 Volk Racing wheel is Extremely Lightweight and Very Strong. The Volk Racing RE30 wheel is a forged wheel designed specifically for Road Racing. This Volk Racing RE30 wheel is 30% more rigid than the Volk Racing CE28N wheels. This added rigidity helps prevent wheel deflection when cornering at high speeds around a Race Track. Wheel weight of this RE30 wheel is between the Lightweight CE28N and TE37 wheels. This Volk Racing RE30 wheel is the Ultimate Road Racing wheel!" taken from Upgrade motorings website

5x114.3 :tup:

Thanks -- inital search found several threads where people just said "5 lug" and one where it didn't specify whether it was x 100 or x 114... then I finally found it.

Curiously, not listed in the FAQ...

Go Volk, they are nicer, but the advan are lighter wheels also depends on the final setup that you setup on your Z

CEs are lighter than TEs - but the TEs are slightly stronger than the CEs

Random question/Thread revival...

According to this http://www.the370z.com/wheels-tires/...html#post59051 the spare tire is a 17" -- is that only for the base model, meaning the sport package Z's get the 18" spare?

Just wondering, because notwithstanding potential brake cooling issues (install ducts???), that would mean we could run 17's after all... I think... no? :confused:

you don't track a spare so brake cooling shouldn't be a big issue while the spare is on... that's something to consider

Oh, right -- I meant that I was musing over 17's either as track wheels or DD's.

The weird width value for the spares is odd though -- also, I'm wondering if the 17's are only for the base model, which would bring us back to 18's as the smallest wheel. especially for a track car that might have upgraded brakes if not the OEM BBK.

Sport Package cars get the 18" spare.

Ah, okay -- that answers that then.

So base model cars could theoretically rock 17's for, say, autox, but might need brake ducts... actually, with small, light weight wheels, it might be okay with just upgraded pads and maybe fluid and lines...

Wonder if anyone has tried that...

18" RPF1 should be the definitive answer for the track :)

Wait...I cannot find any CE28N for less than 3K.

So far, the TE37SL is the cheapest among those the four choices (TE37SL, TE37, CE28N, and RE30).

The new advan rz-df seem really lightweight also, and with some toyo r888's it should make for an awesome setup. I'm also replacing the stock brake pads with some carbotechs, and I might buy a big brake kit in a couple of months. Is the Motul brake fluid worth it? I'm trying to work on the handling aspect of the car first before i get started on the engine.

theres a ton of choices out there:

enkei
advan
volk
forgestar
weds
etc

you want 1 piece forged 18s that should be around 20lbs or lighter. just search for offsets/widths that work.
