nice so they will be coming out with some sizes for 305 and 335 slicks hopefully?

that will be a god send if they are decent slicks!

MJM

Well I know they already have 305s....probably 335s as well since the C6 and Vipers use that.

Sounds like there is going a lot of great scrubs next year!
Looks like we will get an accurate answer on how seconds a lap faster slicks are than R888's as well.

I BET 2 SECONDS!

R888s to A6s are better then that...

with a spec tire in a small pro series like this, you run what they MAKE, they don't MAKE what you want to run. We were luck to Toyo ( the first several years) to get tires that were the right diameter/height, let alone width or compound. Then there was the year that the BMW's ran a Japanese tread and everyone ran a US tread....didn't make a difference until it rained, and the Japanese tread kicked **** (BMW LAPPED the field, even dominating the AWD Audi).

Pirelli might be more aggressive, but I wouldn't hold my breath.

GT Racing Tires

No official word from Pirelli as what tire it will be. Chances are it will be the same as the Grand Am tire was. GA now using Continental. I won't hold my breath on "great" scrubs. WC has to race on the tires they qualify with. Yes there will be scrubs but we will have to wait and see the quality. Either way I am a fan of Pirelli and have faith it will be a good tire.

Conti tires in GA are rebadged Hoosiers. They intend to make their own I hear

GT Racing Tires

Yes for nor now the Conti's are Hoosiers. Hoosier is even doing the track side support.

PeOR

Sorry for being slow (both mentally and on track) - are you saying Hoosier is 2 seconds faster that R888 on a normal track (like 2 minute lap time)? If that is true, I know which tires I will get next time..

PeO. (using R888 currently)

CorvetteZ51Racer

If that's the case, then the tires they've brought must be different than the old GA spec Hoosiers. I was working on DPs when the switch was made from Hoosier to Pirelli. Bolting Pirellis on the car with no other adjustments was worth 3.5 seconds/lap at the long course at Miller. From what I've heard, the initial reactions to the Conti tire are positive, so it must be a different Hoosier carcass/compound.

SIK02SS

On a ~2 min/lap track, A6s are worth 3 or more seconds

I have never been impressed with Pirelli
