what the hell are you talking about?

rims with lower offsets (the +18 and +22 you posted for instance) would have about the same realized offset as the Nismo rims with spacers. aren't they 18x9 +30, 18x10 +30? if not, I apologize but that is what I thought the offsets were.

and running lugged spacers or even longer studs with spacers will give you the same amount of material puttingpressure on your lugs.

the GTC01s for instance just increase the backspacing on the hub face to push the wheels out, so you are sticking the studs through more material anyway. and I sincerely doubt you will have to roll or cut the fenders running a +20 offset on the rear.

in regards to the RE30s being for show. I disagree. Chrome 20s are more for show. lightweight STIFF rims are for racing. Volk makes RACING rims. they race them on race cars. saving pounds matters to race teams, especially unsprung rotational weight. however much the GTC01s weight 22lbs? if the RE30s weigh 18 that is 4lbs per rim = 16lbs off the rotational mass = 3x that if it were sprung weight = 50lbs less weight in the car.

but I totally agree, if you want to cut costs, an Enkei or Advan or Work cast rim is the way to go. they are still relatively lightweight, and strong but won't break the bank. I personally would race on the stock rims but that is just me. especially if I just paid a huge premium for the car when the only upgrades are a bodykit, stitch welded chassis, mass dampers and rims (since you ditched the suspension) they look sooo cool too!

 

as I said, I think the stock Nismo rims are +30 all around.

I personally would go more aggressive, but I took into account him wanting to race and probably wanting larger tires at some point. a +20 offset starts limiting your tire size choices.

 

I know that a +30 rims with a 10mm spacer is EXACTLY like a +20 rim..
I'm concerned about having one more coupling between the hub and the centering hole in the rim.. using rims with lower offset you have a direct coupling, using a spacer you have a sandwich.. that's it.
choice of tires is a HUGE problem with 19" rims if you want track tires.. and about sizes.. for this car a 265 or a 255 is more than enough.. imho over you're just loosing in acceleration and even the grip is not good at all (more tire to deform, less pressure for square inch on the contact patch)

 

yeah, that is the one huge downside to the Nismo rims, I agree and said as much. 17s or 18s are the way to go! not that you need to space them on the track, I just meant for a street car to look cooler. widening the track isn't necessary imo, or necessarily a handling benefit in all cases.

but if you are just concerned about low cost, lightweight track rims I like the RPF01s from Enkei... they are SICK looking and lighter than the GTC01s from what I recall. and cheaper. you can get a set for 1200 or so.

 

Its begging for boost

 

I agree... but you know.. I like girls with nice **** and a little on the thick side than skinny... just my taste.
for GREAT (imho) track and inexpensive rims the 5zjigen are excellent... like the RPF01.
but you'll see from the side pics that doesn't need spacers, unless you like the imho abused look of the rims pulled out of the body with tire shoulder completely exposed

Just saw the pic. Lower it more in the rear...

Looking forward to reviews. Oh and if I got the hipermax IIIs, I probably would have gone with the rubber mounts.

About spacers, I always thought that spacers were just something that could go wrong, but there are tons of people who run them on the track and street without any problems.

 

How much do those Enkei's go for?

You could look for another set of NISMO rims. You can likely pick them for $1700-2000 with tires. Assuming low mileage tires, that $1K worth of tires, so $250 per wheel is a steal.

 

brand new you can get nismo rims for 1200 a set I think

and the 5zigen wheel is the FNO1RC

 

well considering the track use you still have the problem of the 19" rear that limits too much the tire choice.
btw. on tirerack the price for the enkei should be around 1500. nismo lmgt4 (another possible choice) 1500 from brinster on ebay if you don't wait for an auction. 5zigen about 1100/1200.
considering the quality/weight the lmgt4 is almost unbeatable, unless you find volk CE28 used here.. so far I guess is the lightest forged rims available for the 350z... I have to admit I'm a little... "confused" on what to do.
IF I had time, I'd wait and grab the RE30, IF I was making more money, I'd grab the RE30... just because the summer is coming and I need also an oil cooler for the track (I don't want to cook the engine) and I need also specific rims and tire I'd go for the cheap alternative :-p....
It's still possible to sell a set of rims and buy again later

 

Matteo,

Do you plan on corner balancing your car? If not I think you should, it looks like you might be a little high in the rear still. Anyways, you have good logic, and everyone should build their car to their own specs not how other people think it should be built.

btw, I have the Ohlins sold by Impul which have the 10kg front and 7kg rear springs, which as far as I know they are the same as the ones you buy from Ohlins, I can not find specs on them besides the spring rates.

Your car looks good! any plans on upgrading the brakes?

 

I fi remember from Gsedan, the Impul Ohlins are not manufactured at the same plant as the regular ohlins, and does not benefit from Ohlin's technical testing.

 

yes, I plan corner balancing but before I need AT least front camber arms (I'm leaning to SPL).. before I want to try on the track a couple of times. than camber arms and adjustable endlinks (to avoid asymmetric sway bar load).
let's say that in order I need to do:
1) rims and track tires
2) oil cooler, power steering cooler (to preserve the engine, especially in texas)
3) full adjustable suspension and corner balancing
4) exhaust and tune
5) diff and transmission cooler (I need a single side exhaust to open the room for the cooler/s)

somewhere in the middle a POS beater.

for the brakes I'll go with stoptech aerorotor F and R (lines and fluid are coming next week)

 

i was so right ....my god they look way better lowered on coilovers


good job Atar

 

We have a Powersteering cooler already. It is right below the Autech Bar up front.

 

all 350z have one... I'd like to put the nismo one. on a slow and "nice" track you'll have your PS fluid boiling with R comp. (no problem with the stock tires at least for me.. but you know.. installing an oil cooler, when you have everything down.. a bigger PS cooler is just 150$ and some fluid, is not going to hurt.)

 

wow, a drop is really all that the nismo needs. Your car looks great.

 

Add a lightweight flyweel and a 3.9 diff onto that list.

 

Yes, you are correct. They are.

10mm is my plan as well. I had measured my 285mm rear tires against the fender and 10mm will bring them to the edge. With a planned 20mm drop and -1.5 camber, it appears I will have to roll my fenders. I am really looking forward to the results!

 

what is the stock final drive? 3.7? and if your changing the R&P you might as well get a GT L.S.D. and if your going to get a flywheel you might as well get the coppermix disc and a PP.

I should of saved up for the 380RS-C...
