Track wheels
 

I am prepping for a track day at Sebring and wanted to get some track wheels that I can put some good rubber on and save my stockers for daily use. My plan was to get some base wheels, but if there are better options out there for about the same cost ($500-$700 used it seems), I'd love to hear them. I have Sport brakes, so clearance is also something of concern. I've been searching Discount Tire and Tire Rack, but I can never find a wheel with a good offset.

Any advice?

Anything 18x10 or 18x10.5 all around in the proper offsets. Run 275-285 all around

Im in the same situation. Been looking at the eneki PF01 and the forgestar F14 in 18 inch. I am also looking for rims that i can use on the 370 but, would eventually go on a specz so 10" max width. The offsets are giving me the problems. The F14 have alot more options though. More than your budget too.

Nothing wrong with running hubcentric spacers and proper hardened/extended stuff to get offsets where they need to be if too positive.

I currently run PF01 in 10.5 all around. Et38 front with a 10mm spacer to clear the suspension and et15 rear. I plan to get NT03 in 10.5 all around with a spacer in rear for clearance.

Agree on the spacers and ARP studs. This will end up being a winter purchase for next year. The 2 wheels I mentioned above are the cheapest quality track wheels I have found. Specz can use anything 18x10 and no less than 18.5 lbs unless you go with the PF01's which are the recommended wheel.

with 285's can you run that with the stock fender liners and fenders on the front? How much camber are you running?:tup:

yes, i run 285/35/18 RS3s with full compression articulation and no rubbing at -3.2 front (which is a pyrometer verified ideal angle for my setup) and -1.75 rear. When i run my 275/35/18 RC1s, i run a 15mm spacer up front and a 10 in back, still no rubbing.

I had to google RC1s. I had no idea Maxxis made a slick. Good price on them too. How do they compare to the NT and RS3... limited tire budget so looking for best bang for the buck for TT next year.

grip level is similar to the NT01, but communication is better and sidewall/carcuss construction is stiffer. end of this month will be my 6th track day on them, so far they have not shown a dramatic drop off in performance. alot of the miata guys using them are seeing alot of consistant heat cycles outta them. I'd recommend trying a set yourself. Their durability and drivability i feel are their best attributes

price range isnt there but i love my RPF1's. maybe buy 2 then 2 more later. you cant beat the weight and i love the look and stance. i have 18x9.5 +45 with a 20mm spacer and 18x10.5 +15.

i think i have question though. since some run a smaller front wheel like me, would it make more sence to not run square? a smaller width can lower the tires width no?? so 295 front and 285 rear might make it more square then 295/295 or 285/285??

PS, money aside i still want to test all setups. i get the square but i just LOVE a fat rear. i really want to test 285/285 and maybe 285/315

acutally i just looked at tire rack, in a A6 id have to run 295/30/18 and 315/30/18 to keep the diameter close. it may not be square but the smaller front wheel its mounted to would bring the diameter closer together. so it really wouldnt be a true 20mm gap.

I've been running my base wheels at Sebring and after 8 days on the track I'm shopping for wider ones. Instead of buying a second set of stock rims I would look for a set of wider wheels because if you enjoy tracking the car you will want more rubber in no time. When are you going to Sebring and with what group?

If you really still want stock 18" rims PM me, I will have a set of 18" available soon with BMG GForce comp 2s on them. The fronts are in good shape but the rears are about done.

Hi my friend!!! you are not going to have any problems if you run the 370z base wheels with your Sport Brakes. I have a 2013 370z Sport Package and when i sold my oem wheels one of my friend give me his base wheels to use the car... they clear the brakes with no problems :tup: here is a pic :)

I have more pics of the car with those wheels but unfortunately my iphone fckt up and i lose everything on it

You have a supercharged Z, right? If so, I'm the guy that came up to you for a chat at the last NASA event :)

I will be at the event in October....just registered yesterday. I would love to take your wheels of your hands! Sending you a PM now.

Tons of good info here, too. Thanks a lot guys!

That was me, are you bringing the Z in October?

i HAVE A VIDEO TOO TESTING THE BASE WHEELS BUT I TELL YOU WHAT HAPPEN TO THE DAMN CELLPHONE :shakes head:

I ninja-edited my post, lol.

Yep, I will be there for sure. I just ordered my oil cooler yesterday, so really wheels and tires is all I need at this point since I have SS lines and whatnot.

Are you coming out? If you haven't registered yet, they have a $150 coupon available.

I originally had PF01's 18x10.5" square with the 38 offset and 10mm spacer up front. I eventually ditched the 10.5" front rim for a 9.5" wide +35 which did not require a spacer. I had broken a stud and was sick of switching back and forth from stock to extended studs. I run a Toyo R888 275/40r18 square. I'm looking at getting NT01 275/40r18 front 305/35r18 rear for my next set.

I will be there for sure, I booked the rooms at the track hotel before we left last time. It will be cool to see another 370z out there, I'm always surprised no one brings them out.

basically if the wheel is too narrow to support the tire width properly, which i feel 9.5 is too narrow for 285, then the sidewall dynamics are not ideal. the tire contact patch doesnt produce grip until the sidewall is in tension. this is why i like to run with a slight stretch to "preload" the sidewall tension. when you run too narrow, you increase the sidewall tension delay. also when the tire is to wide for the wheel, the contact patch shape gets rounded.

Before buying wheels read this: http://www.the370z.com/wheels-tires/...ud-length.html

I am running Forgestar F14 18x10 + 34 square setup (without spacers) with 275's all around with no problems for my track setup. Sport Pkg brakes. Cheap setup and does great at the track. As the above thread states, you will have to run extended studs or bolt on spacers with any aftermarket wheel to get adequate thread engagement on aftermarket wheels. 50mm length studs will allow you to retain the ability to run OEM wheels and lug nuts without spacers.

Prior to my buying forgestars, I got Enkei NT03+M 18x9.5. Great wheels, but there is not a square setup that will clear the akebono calipers (IE, you need spacers in the front).

If anyone wants these wheels they are for sale though.

Read T. Just bought a set of 18x10 +34 F14s myself and want to run a 10 mil spacer in the rear.

Just want to verify that a 50mil stud with a 10mil spacer will work with the F14s in the rear.

You didn't specifically say these words anywhere I saw.

Thanks!

With those wheels I use the 10mm spacer from Z1 here: CNC Aluminum Hub Centric Wheel Spacers 2.5, 5, 10, 15, & 20mm

Currently I have the Nismo "Long hub bolts" with 50mm front and 60mm rear (just to make it easier to thread the nut on). I'm about to switch ARP's extended studs next week (same length all around, whatever "25mm over stock" is, I'm sure it will work - I *think* they're even longer than the Nismo 60mm).

I can check on my car later today (I have a ton of spacers), with a 50mm stud and a 10mm spacer you are effectively making the length of the stud back to OEM so I'm not sure you'll have enough threads poking out of the wheel. It'll be close, and personally I'd rather have my back wheels a little sunken with tons of threads engaging than flying off at the track.

EDIT: On the back wheels there's more thread than I thought. With Z1 10mm spacer, Z1 50mm studs, and Gorilla lug nuts I was able to get about 8 rotations on each lug nut by hand. Also, if you want to buy any spacers I'll have these for sale (brand new never used Z1 hubcentric). That said, if these wheels are just for track I personally would rather not run any spacer unless I have to.

Hey ValidusVentus, I was just looking at the "top lap time track records" thread and saw you have the only time there at CMP. How long ago did you run that? I was down there a few months ago for an HPDE.

Just looked at my pic folder, Feb2013. Only been there that one weekend.
