wheels and tire all 4 same size for track????
 

I'm planning on buying Enkei NT03-M in this • Size: 18x9.5, 27mm Offset all around for track, and 275/35/18 all four. and my ? is! this will fit my 370z nismo?, and i have 15mm spacer all around. i am lowering in Swift Spec R Springs. i am very :shakes head: confused in the offset size for clear my front break,please feel free to comment all yours espertis. thanks :ugh2:

i am going with all 4 in the same size for rotate the wheels.

If you're going for new rims, why not go at least 10" square? The 9.5" even with a spacer on the rear might be sunk in a tad.

FWIW I'm going to be going with a set of four Nismo rears on mine. Also on Swifts, but with adj camber arms, etc. At -2.2 degrees.

Test fit of rear on front:

that will work. one of my setups is 9.5 +46. I run a 20mm spacer in the rear and none on front and they fit just fine.

Probably not a bad setup but running a +27 with a 15mm spacer in the front will be horrible. Wheel will stick out way to far!! I have the rpf1 in a +45 with a 20mm spacer and I stick out maybe 1/8". You're talking about another 13mm further plus a heavy spacer. Although that is with my OEM low camber. -2.5 to -3 will bring it in. But you at +12 overall will not be able to tuck it back in. Lowered on swifts and you hitting bumps I can bet you'll hit the fender with the tire. In the front I'd stay +27 or maybe at most a 5mm spacer for a +22 over all.

Also with a 9.5" wheel and a +12 overall in the back its still going to be pretty tucked in. A 20mm spacer would be nice but that's your call buying a heavier spacer.

Because now you have to worry about front fitment and just adding unnecessary weight for the track. His wheel also doesn't come in a 10" that will fit.

I'm running Enkei PF01s 18x10.5 +28 front +15 rear with Toyo R888 275/40r18's square. I was really looking to do a true square setup (offset and everything, maybe using a spacer in the rear) but then decided to just ditch the spacer altogether. Absolutely loved this setup at the track, although I've only done one track day on it so far.

Pic of the front? That's 10mm further out than mine now and I was thinking rpf1 +15 all around in a 9.5. This would be identical to your front on the outside but 26mm more room on the inside. Please include suspension and camber if you could.

I have Enkei PF01 +35 offset with a 25mm spacer at the rear and a 12.7mm space at the front and 2.5 neg camber at front/1.7 neg camber at rear and it is
a) flush
b) brilliant from mechanical grip perspective.

Current tyres are 265/35R18 A048 Yoki's (got a special deal on cost) and 275/35R18 NT01R on the rear. Will go Yoki all round when rears are shot

thanks for the reply to all!!! the problem is my front offset number Right?? more number offset is more room for the brakes? i will go with front 27 offset and no spacers and the rear with 15mm spacer or 20!! now is more reasonable??? :shakes head: i have much problem with the offset in 18" to accommodate the brakes..

i like your numbers !! all flush.... you are in 10.5 or 9.5?

the problem is i dont want buy the wheels and then the front wheels dont fit, or fit but are to far away from the fenders. I want same numbers all around for track use only.
please feel free to put your same all around
18wheels numbers and offset for all 4 corners!!

9.5 inch

Here is a pic when I had the 10mm spacer up front. It's not a huge difference with it off to be honest. I have Eibach springs and camber is something like -2.5 front -1.6 rear. Those are an approx from what I remember.

Yes, and that is where the AT LEAST portion comes into play.

He could go up to their 10.5" which does fit. The spacer on the front would have to be dropped though. IIRC there was already a 370Z running those rims in 10.5's square for a track setup, I think he had aftermarket brakes though. I'm just not sure if they'd clear the front brakes. FWIW the rear Nismo rims 10.5" have an offset of +23 and they cleared the front brakes for me.

The 10.5's would be very flush on the rear with the right spacer. The 10.5's would probably stick out on the front a tad without some negative camber.

Just my opinion of course, but I'd rather have the extra meat if possible. That's also probably because my 305's on the rear still slip too much. It's worth the few extra pounds to me. He can always upgrade brakes, and add more power, etc to compensate. vs. selling his rims and tires and then buying another set in 10.5 later.

Either way, rotating tires FTW.

So he wants a track setup (lighter the better), a 275 max tire, and you want him at "at least" 10" (which makes no sense at all with that small tire and unnecessary weight)? Great advice. :tup:

I understand it'll fit but its totally not necessary and will hinder performance. I understand a spacer can hinder performance too since you could just find a wheel and offset to work without one, but I'd take the spacer at the hub over a 10.5" wheel since all the added weight from a 9.5" to a 10.5" wheel will move the weight out further from the hub which is bad.

On a track car you really don't want to be near flush. You have no idea what certain turns will do with your suspension choices and rubbing and killing a tire is not a good thing. If he wants those wheels I say go for it. They should fit perfect with no spacer at all keeping the weight down. If he wants to track plus go for the "look", then he might end up buying a big rear spacer and a small front spacer.

As for more meat I'm sure he'll do fine with 275's square or even 285's which is the max for a 9.5" wheel. Why you're slipping and you think you need more meat, I'm sure tires could be improved maybe or a better alignment or just ease up on throttle exit.

And yes, rotate FTW.
