Hoping to get some advice on nt03+m
18x9.5 +27 front and
18x10.5 +30 rear
Are they good for a 245/275 r-comp track setup or would the tires be too stretched? Sorry don't have much clue: My instinct would tell me to better be right on the spot (midpoint of the rim width range of the tire) for the demands during road tracking. Not sure what is worse, stretched or too narrow rim...


Also do you guys have any recommendations on the enkei rp03 for track use with 245/275 setup in terms of wheel width and offset?
I was thinking
18x8.5 +30 OR 18x9 +18 FRONT and
18x9.5 +38 OR 18x10 +22 REAR

I am just so clueless how bad it is to have different offsets than stock.
At least I think these offsets should fit fine, but not sure which is better for the Z.

THANKS!

Check with members Rob Hines or his dad merlot350Z. Rob runs Enkei wheels on his T2 350Z and may even have some rims/tires for sale.

I run the NTO3's and you can fit much more rubber than that. I run 265/35/18 front and 295/35/18 rear. You can even go 275 in the front. Tons of traction!

Do you know if 245 / 275 fits well enough for track use or is the rim too wide?
r-comp tires in 265 and 295 are I think much harder to find.

Thanks!

I have the NT03+M in 18x9.5 +27 fitment, front and rear. I like to go cheap and be able to rotate the tires. For cast rims, they are very light (~20lbs). 265/35/18 all around, and I will try 275/35/18 all around next. Fitment is great, however, I did put in a 5 mm spacer in the rear because I don't like having the rear tucked in so much. So, you have to figure in cost of spacers and longer studs to the wheel package if you care about how it looks.

The 18x10.5 +30 will fit nice if you want to a stagger tire sizes.

I guess it all depends on your suspension, alignment, and driving style. I have 500lb springs front and rear, and I think I'm on the loose side. I could probably go with some stagger or go with a slightly softer rear spring.

IMO, I think it's a big plus to rotate the tires and add some life.

Those tire sizes will work, will probably understeer. 275 all around would be a great setup too.

First...........Enkei makes a great wheel and I dont say that because they sponsor us. They sponsor us because we started using their wheels and had some sucess and wrote a letter telling them how much we liked them. We use the RPF1 wheels on our Z T-2 SCCA racer. The rules allow us to use a 9" front and a 10" rear wheel combination. These wheels weight in the 18# range. 18.4 for the 9" and 18.6 for the 10" I think. We run Kumho 710's in the 285/30 x 18" size and they fit just fine giving us a wide tire patch meaning we get better speed thru the corners. That tire also gives us a good temperature reading even at Roebling Road in July when its 100 degrees at the track and track temps are in the 150 range. The 10" rear fits perfectly with no spacer. We run the Brembo brakes front and rear and that means that we have to have a 20mm spacer on the front 9" wheels for clearance. With the stock, smaller brake calipers, you dont need the spacer but putting on a 15mm spacer will give you a wider track. I had several sets of these size wheels but have sold them all. I will probably have a couple more sets this winter or early spring. Mark is right, we do have some take-off Kumho tires that have anywhere from one qualifying session at the runoffs to sets that have 12 to 16 laps of qualifying and one 40 minute race from VIR, Lime Rock and the runoffs. Call Rob Hines 703-989-1536 after 28 November for prices and availability. In 2007 we will take orders for take-offs starting in April after Summit Point.

I am running those rims with 275/35/18 F and 315/30/18 rear Nitto NT-01 tires on a G35 coupe. The Z car may not have as much clearance in the well, especially the rear.
On the G, the rear does not need a spacer, but only because I am running an AP Racing competition hat on the rotor (the standard offering was shearing allen bolts from heat fatigue.....very distressing to hear a whirrrrrr-thock noise at 160mph from a flying bolt head!). Otherwise you will need a 3 to 5 mm spacer in back. If you adjust the camber in front to about 3.5 degrees negative with adjustable control arms you might get rub, so be careful and perhaps a 3mm spacer there too.
The wheels are fantastic: light, strong and look excellent. The only pain is cleaning them!! The Nitto tires are also outstanding for grip, sidewall modular response is quick, and in dry weather the large treadblocks are awesome. The tire should not be run in the wet. Negative is that with the radical sipe design the tire is noisy, and not really something to run on the street as a daily driver.
