Op looking at your video my advice is to replace your clutch first, don't worry there are buyers for your use clutch, I sold mine for a regular C6 and got good money for it, you need the clutch to release as you let the clutch pedal go, in that way you will do a better burn out, then a set of Nittos NTO5R on your stock rims will do everything you're trying to do and can take that can way down into the ten's. Nitto NT05R will also be a very streetable tire by don't like rain.

For those of us running Z06 rear calipers what 17in wheel options do we have? I would not be oppose to grinding the calipers to make them fit.
With this in mind how much of a difference would I see in traction from my current 345 35 18 MT ET to a 17in tire?
Thank you

Weld and CCW also make 17"s that fit. I believe c4 zr1 replica wheels fit just fine too.

275 mm is the same width anytime, it has nothing to do with the side wall height, the side wall height is the percentage of the width, like a 50 series, its 50% of its width, which means a 275x50x15 is 275mm wide, 50% of 275mm side wall and a 15" rim diameter. Therefore a 60series is a much taller tire than a 50 series and then we have the 40, 30, 25 series which is much lower.

Good advice... I should change the clutch, what do you have in your rig? Also I do like the idea of the NT05R... I want to keep the stock wheels id hate to be married to a Drag tire set-up because I do mostly street driving! These Nitto Invos are spinning 3rd gear @ 80, its very unsafe fish tailing in two lanes on the highway >_<
.. you can buy cheap wheels and hoosier drag radials for same to less..

I don't really see any advantage of going with a 17 vs your 345 18 inch MT setup. Not for what you do running street pulls and the 1/2 mile. The only tire I can think of for your car in 17's are the Hoosier 335/35-17, but you're not gaining any sidewall there since its a shorter tire. I'd leave your setup or go with a 15 inch spindle setup to really get the benefit of the extra sidewall. 1500+hp is a lot to ask out of a shorter tire on an unprepped surface.

You can get optimal hook on the 17's but the 19's wont be that far off and for what your looking to do. You will easily run well into the 1.5's on sixy foot times with the 19 Nitto NT05R's and no rim swapping, etc.....
Go with what suits you the best.

Yes, the rules changed in 2013. 2008 or newer cars are not requires to have a rollbar until 9.99 in the 1/4 per NHRA rules. My last 1/4 pass was 10.87@129 at Texas Motorplex. They did not say anything about me not having a rollbar.
As far as tires, I use Nitto NT05R's, 305-35-19 on a spare set of stock C6 wheels. I would like to 18" and switch to MT, but I cannot find a 18" wheel with a 79mm offset.
For 60", my best time on my nittos is 1.69.

After driving my car tonight & violently spinning 3rd gear @ 80+ MPH... Not only do I need a tire BAD for the sake of not crashing / losing control but I don't wanna loose to a car with less power because I can't get my car to put the power down! Thats all I need >_< Ahhaha but safety is a big priority... Need a great street / strip tire, I do more highway runs then hiting up the track... I just wanna be prepared for the track for track rentals and hit a ten second pass with better driving / traction

I hear ya... I plan on running em on the street also, So it can hook my power on the streets of Mexico if you know what I'm sayin lol After driving my car tonight & violently spinning 3rd gear @ 80+ MPH...

I just wanna be prepared for the track for track rentals and hit a ten second pass with better driving / traction I have rear wheels that only take 20mins to change out for track or street pulls that's the only way to get the traction you want.
my advice would be to get some sticky 19s for everyday and a set of 17s like M/T 295/45/17s for the weekends! this is what I do and they last longer too. here's a deal for you too http://www.ebay.com/itm/400603888752...84.m1423.l2649
I just got these for some street driving wont hurt my feelings to burn them up at this price

The aspect ratio does affect the actual tread contact patch. The overall width can vary from manufacturers given they may not be measuring the tires on the same width rim. Track prep on a race night vs a Test and Tune night is no comparison. A wider tire is what I'd recommend if predominately running the latter, otherwise I'd opt for the smaller of two tires as it'll ultimately be faster if you can hook it. FWIW a 335/30r18 Hoosier has been 9s and cut 1.4s and an option that I didn't see mentioned, hope that helps.

Original poster, I am in the same boat as you, but I am running an A6 Automatic with a 3800 FTI stall converter. No traction, no traction...
I was thinking about or looking into getting another set of front GS rims. They are 18" by 9.5". Then having them widened to 12" from these guys: http://www.weldcraftwheels.com/index.html
I can then run the 335/30/18's Hoosiers that have been recommended here. And my front and rear wheels will match and look more stock. I know they are a little bigger than I need for a prepped track. But for an un-prepped test and tune or no-prep event I might need them.
They are also 1 inch shorter than my current 345/30/19 Pilot Sports. So my overall gearing will drop a little too. That doesn't hurt.
Swapping out the rear wheels takes about 5 minutes. So having a second set is not a big deal for me.
Guys feel free to let me know your thoughts on this.

I think the smaller tire will be plenty on the prepped track, but I am concerned about the un-prepped track events.
What made you decide on the 11"?
