19x11 square for stu
 

Anyone actually running 315's on 19x11 square? There seems to be no off the shelf wheel options. Thinking of going full STU but nothing short of forgestars (kinda heavy) seem to be available.

It should work, Hotrodz is using 18x11 square for road course, but you need a low offset like +18.

You need 18x11's.

ForgeLines. Make any rim spec you want. One of the lightest and strongest rims. Order now to have them by spring.

If you want to spend some money TE37's can be had in 18x11 +18.

For much less $$$, you can get a set of Forgestar F14's 18x11's made to the offset you want. Also, don't confuse Forgestar with Forgeline. Forgeline wheels like Rusty suggested are higher quality but also much more money. For autox, Forgestars aren't a bad option.

fwiw I run 18x12 Forgestar F14's wrapped in 335's on my autox car.

They make TE37 Ultras in 19x11.

Spend that money dude :ugh2:
You’ll always make more :iagree:

About 1/2 the cost of Forgelines :tiphat:

Unsure your suspension setup; but most run 18” wheels to keep overall wheel diameter a bit smaller for clearance :ugh2:

19x11 would work with either a 295/30 or 305/30 (26—26.3”)
But definitely with an adjustable suspension :ugh2:

I want the 19's due to the dimeter of the tires available. Presently running the 285/35/19 on the OE nismo wheels, which gets me 67 mph in second and 123 in 4th which works out well for me as I just get to the rev limiter of 4th in two places on my local track (NCM). STU limits width to 11" and 315's so I'd like to be able to run 315's on 11's, at least for autocross.

The car came with stillen gen 3 cai. So for autoccross I'm bumped to STU, for Time Trails, unless they change it, the nismo gets bumped to S2. I figure I may as well build the car for STU which puts me in T3 for TT. Podium T3 cars last year were slower than S2, the Nismo does not belong in S2, and I've told Jon

I added the hotchkis front bar and Koni sports all around, carbotech Xp12/10 pads. car came with megan Y pipe, ISR catback with the resonator cut out. The car will also be getting amber arms and coil overs (not sure which ones yet). loads of options foreverythign else, the wheels choices are few.

The clutch while it isn't a real problem yet I figure Id replace the clutch, csc etc in the off season which makes it a good time to do headers and high flow cats, LSD and either add a resonator or replace the exhaust completely (it drones, but does meet sound restrictions for the track)

My brother has CF1 open lug for his Mustang, I don't know what he hit, but maybe it was a small stones, as they didn't left any mark on his car anywhere else, but the result two small bent on two wheels :shakes head: also, they were heavier than my ZE40, both wheels 19x10.5 (mine +22 and his +32)

Trust those of us saying to go with 18's. Get yourself a set of 18x11's and run 315/30-18 Yokohama A052's.

You also may want to check the STU rules as last I knew clutches had to remain OE. Also you'll find the xp12/10 combo is overly agressive for autox. Might want to think about swapping pads between autox and track duty.

I have the ZX3R's. Mine are not heavy at all. I've punished them since 2012. Chit load of trackdays, and over 30,000 miles.

I don't love the yoko's, I got a set for my miata, kinda remind me of the old bias ply R comps. Loads of stick with no sidewall. The 18 size only costs me about 3 mph in second but 6 in 4th. Fine for autocross, less ideal for track, I'd rather not have to do a bound up dogleg downshift cresting turn 16 at NCM at 120+ mph, been there done that, sketchy AF.

I'm pretty familiar with the rules. The clutch and csc to go in is a stock.

Yes these pads are a bit more aggressive than most seem to like in this chassis, I ran 12's front and rear on my 350Z (GT). This chassis gets way twitchy with that much rear bite, also the larger akebono's and the OE abs don't seem to know what to with this much bite either. I'm used to the aggressive pads at autocross, anything less, is well, less.

When we received them, we weighted them at 28lbs, ZE40 was around 20lbs, and the incident he had, looks like we didn't have the best luck with them, although, he loves the look a lot.

Two of my friends also got forgeline for their cars, and I am thinking about getting them for my TT, we got a pretty good deals on them from custom wheels for less.

From what it sounds like he is not really looking for advice or any other recommendations. It seems he wants conformation of his own idea and so far there is no one on the forum or any circles I know of that is running 19x11 for any kind of autocross or track use. I guess that is not enough evidence for him to do something different than he is thinking. :ugh2:

The question was/is: "Anyone actually running 315's on 19x11 square?" The "answers" haven't exactly addressed the question as asked. The fact that 315's don't seem to be available in the 19's makes the question flawed to begin with.

Are you running the 315's on 11" square? What wheels and offset's are you running?

I can see his point about tire height, speed and trying to save from having to do a up shift just before hitting the the turn. I did the same thing almost. But I raised my rpm limit to 8,000 so that I can carry the gear farther to keep from doing the up shift, down shift thing.

It was mentioned earlier in the thread I have two sets of wheels in 18x11. The Volks are et18 and my Enkie's are et16. I have been running NT01's in 315. Will be running either Nankang or Hoosiers. I will be in either TTU or TT 1.

I totally understand where he is coming from and his logic is not wrong. I think if he was on to something then he would have received a lot of comments supporting that setup. What I have seen mostly is just what you have done in moving the rev limiter up to 7500 or 8k. Some even run 4:08 gears which means lower mph per gear but you won't have to short shift. I am actually going to 3:3 gears, using an auto rear end to make gears taller to compensate for the smaller wheel and tire diameter. The results equate to higher mph per gear and the net result is the same as running 3:69 gearing.

11" wide is wheel and 315 wide tire is max allowed in STU so that's why I'm looking to see if anyone actually runs them in STU. The 285's on 10.5 wheels are quite popular for the 350Z. I'm not suggesting that the taller tire is right for STU or everyone who tracks. I just know that it's right for me on my home track. I ran a few combinations on my 350Z and when I switched to the 285/30/18 from the 265/35/19 it cost me 8 mph and made for some uncomfortable shift points. With this car and the 285/30/19's the shift points are ideal. I don't have to upshift to 4th heading into 10, I'm just hitting the rev limiter in 4th heading into 16 and 1. Might well be totally wrong on another track, but ideal for me on mine. Gear changes aren't allowed in either of the classes I run the car except the update/backdate that would allow me to run the 3.916 which would be counterproductive. I run SCCA events, sound like you run NASA events, and with a turbo you're clearly in less restrictive classes than I run.

So you run the +16 and +18 (no spacers i assume) 11" wide wheels up front with no rubbing? Fenders rolled or cut? Since you clearly aren't running STU where a roll is legal but a cut or flare isn't I have to ask. Also how much camber are you running?

No body work at all and no rubbing. My camber was -3.3 up front and -2 in the rear.
