How would this set work out?

Volk CE28N, 18x9.5, +22
Pilot PS2 255/35 18 all round

Is this too little tire for a high HP application?

 

How much power we talking? Under 400?

The 255/35 is pretty small sidewall wise.

You'd be better off throwing a 275/35 on them or a 255/40.

 

466HP/406ft lbs to the wheels.

 

With that kinda power I would go with a 295 no lower then 285. With a 10wide in the back. For the front you can get away with the 255.

 

^ +1

But I would recommend something wider up front anyways just to get rid of the little bit of understear the Z has.

I would hold out for something a little wider.

 

If the price is really good, you could pick these up and then get some 10 or 10.5" rears. I'd go at least 275/35 on the rear. If you're patient, you could eventually sell 2 of these here in the classifieds/marketplace.

 

I was under the impression that a square set up was the most desirable track configuration. Is that not true?

(I thought those would be too narrow.)

If you can run a 285 on a 9.5" rim, then what is the advantage of running wider? Won't this just add unnecessary weight?

 

Well running a 285 on a 9.5 is really an oversized tire for the application. This was actually hinder your handling and the sidewall won't be as rigid because it hangs outside of the lip.

 

How would these specs work out?

Enkei RPF1 18x9 (+35), 18x10 (+38)

Let me know what you guys think...

 

Go with 18x9.5 +15 fronts and 18x10.5 +15 rears.

 

^ +1 the RPF1s come more aggressive than the 9/10 stagger and those offsets are too high for the Z.

 

Check out these guys Myles. https://my350z.com/forum/wheels-and-...-shipping.html
They are in Michigan and the price is good, I've looked into them before.

 

If your looking into track wheels I will be selling my nismo wheels this winter. They are off my 2008 350z nismo. 18x9 and backs are 19x10 of course made by rays.

 

Good option^

 

I have 5zigen fn01rc 17x10 +12 all around.A beautiful setup may I say.Let me know.

 

These are both heavy (compared to the Enkei RPF01) and have zero chance of clearing my brakes.

A complete Enkei setup new from the US is only $1533 including shipping. Perfect offsets, perfect sizes, perfect condition, my choice of colour...

I think that'll be hard to beat.

 

I want to run 18s front & rear for improved tire selection and reduced weight.

I already have 19" Volk GT-C wheels for street use.

Thanks, though, those are great wheels!

 

Ya makes sense.
ya they really are, thanks

 

The RPFs are hard to beat for value. Their new model is nice too.

Normally yes I would say go with a squared set up, but with 450+hp on the rear wheels I would put as much rubber as possible back there.


The reason for the squared set up is so that the front does not break first (understeer) and you have "equal" grip front/rear. However, you have 200hp more than most, so you need as much traction in the rear to actually use it. A 265/285 setup would be good on that 9.5/10.5 wheel combo. Are these going to be street tires on these? A 305 out back might even be worth fitting (on wider wheel of course).

 

Thanks for the detailed answer, GT-Rob. Exactly the kind of info I was looking for.

What's the widest tire that is recommended for the 10.5" rim? There has to be a point of diminishing returns on the weight:traction scale if I go to an even wider rim.

Will a 265 fit the front without rubbing? Mods needed?

Is the +15 offset frt/rr still the sweet spot?

For tires, I need (at this point, anyway) to stick with something that I can install at home and drive to the track. Thinking about RS3s. They seem to be generally accepted as offering the best traction around. I'm open to suggestions though.

Thanks!
