Hey guys -

I am looking for recommendations for a race-only set of wheel and tires for road racing. so far the TSW Nurburgring in 19/19 looks to be my best fitment with these tires:

backs
305/35-19 HOOSIER R6 (-0.7% )
295/35-19 hOOSIER r6 (-1.2)

Fronts
235/35-19 Hoosie R6 (-0.6%)
265/35-19Hoosier R6 (1.2%)

Let me knoe of an othr options you have tried

i was at a track event last weekend and the corvette's that crushed all had more rubber than wheel. you can find a 18 inch wheel that will fit your c7 z51 front and back in 9.5 and up to 12 inch wide. and then you wont be talking about a 235/35/19 front( that is too skinny) the 265 is not much better, the wheel wells have been about the same size sence the c5 corvette so im sure you can run much larger tire than your talking. back to the event, when i asked these guys(two of them) how the hell do they fit a 315/30/18 on a 9.5 wheel( 2010 GS, 2009 ZO6) on front stock wheels? by trying it ! they both had the 345's on the back on the 12 inch wheels. enough on this i know i did not help the way you asked i just dont want you to get stuck with dodge neon size tires. once again horsepower without tire width is a joke!

If I may make a suggestion, TSW Interlagos may be something different and if you're picky are a bit lighter. Are you looking to autocross, road race?

Edit: Stupid question, you said road racing.

Yeah, a better selection of tires can be found in 19/19 or 18/19.

And 265/305 front/rear tire sizes are a good choice on 9.5"/11" wide wheels. Wheel offsets should be about 52mm front and 74mm rear. (Well, a 59mm front wheel with a 5mm spacer is 54mm.)

If you want to increase front tire size while holding 305 rear tire size then the Oz Superleggera III can be found in 10" to 11" front wheel widths listed under the C5. Then only an 11" rear wheel can be found listed under the C6.

If wanting the 285/35-18 and 325/30-19 tire sizes, that calls for a 10" wide front wheel and an 11.5" wide rear wheel. Wheel offsets should be 56mm front and 79mm rear. Lowering to tuck the tops of the tires is required and rear brake duct clearance might be a problem.

Finally, the RS-3 Version 2 and the AD08 R have Corvette tire sizes up to 305. Pilot Sport Cup 2 is about the only choice for 19/20 tire sizes. But all of these tires are an alternative to R-comps

RE-11's have a lot of sizes too in the 19's. Toyo R888's are relatively diverse too but those will wear out FAST.

I think a nice setup would be 305/30-19 rear, 275/30-19 front. If you have to put a 305 on a 10.5" wide wheel (you'll also gain a TINY amount of tire wall doing this too), it's by no means the end of the world but 11" is ideal. 275 really should be on a 9.5".

I love the Nurburgrings, so regardless what tire you choose, please, post some pics when you get them installed

Good luck.

I am running Cray Brickyards

18 x 9.5 front with 275/35/18 Pirelli take offs from World Challenge
19 x 11 Rear with 295/30/19 Pirelli

Whole set out the door with tires $1,800

Will have them on the track next weekend.

Are those on a Z51 and clear the brakes and ducts?

Thanks!

leadville1

Perfectly!

The Cray 18x9.5 fronts/19x11 rears I ordered just came in... and the front rims do not clear the Z51 calipers! (and yes I removed the OEM pads w/ balance weights). The rears fit (barely... just clearing the bearing mount).

The problem is the reverse barrel design.

C5 Z06 wheels made for GM by Speedline in Italy, 18x10.5 on all four corners, fitted with Nitto NT-01's in 315/30/18 all around. A lot of rubber, lightweight, and well priced. $300 per wheel, $300 per tire. Can rotate tires around to even wear.

Doesnt that chew up the brake ducts?

Higgs Boson

no they clear the brake ducts but they will rub the car next to you.

i am running 19x11.5 with 325s and they don't stick out (but they almost do).

Magister Ludi

I'm interested in this setup. You run this on your Z51 with no problems? Any photos so I'm clear what wheels you're using? Thanks.

Edit: I found the wheels. Still curious about clearance. How about lock to lock? I know it shouldn't be an issue for racing, but curious.

Baron7700

I think, is it MTI? Is running the exact setup but said they were rubbing the brake ducts :/ Im confused now. I would love some NT01s on this setup to use for the autox events I do almost once a week. Would sure be better than chewing up the regular tires

Are you still running this setup? I am about to order 315/30/18 for front, 325/30/19 for rears (NT01); excited!

I've been running 275/30/18F, 305/30/19R, and it feels like I need more, especially at the rear (can't put power down fast enough).

Wheels are 18x10.5 ET52 (4mm outwards than yours; should provide a bit more ducitng clearance), 19x11.5 ET83 (this should be OK. OEM is 19x10 ET79 IIRC).

No, sold my car due to AFM failures (nice to know Tadge has decided to eliminate the AFM valves from the 2017 M7's, too late for me) so my wheel and tire setup is for sale. But it worked very well.

Newton06

I read about these failing for those that track their cars and thought it was mainly autocross.

At the last VIR full event with temps in the mid 90's I threw P12F0 & P12FD codes.

Will GM replace these if you have LT's & x-pipe installed?

Will removing fuse 32 eliminate the CEL?

Don't mean to hijack your thread, so PM if you'd like.

Thanks!

I'm still toying with the idea of this set up.
Any fender rubbing up front?
(When I put 315's on my present wheels (18 x 10 CCW's, offset: 58), I can't keep them from hitting the lip of the front fenders)
Thanks.
