I ran the Hoosiers in the new CUP size in Atlanta. They were the 80 compound in front and 100 in the rear. We used the Michelin setup, but the car was oversteering a bit (bigger fronts on their cups) so we adjusted the sway bars and it was fine.

I had problems with a sticking throttle cable, so I was not up to max speed but they worked fine. They are great if you like to drift a bit. I don't, I like the car on rails so I was not so comfortable in the last fast downhill turn, but everywhere else the car was great. I think they are better than the Michelins at the top of the hill T3, the car stayed very stable there. They were better than the Michelins in the following long left turn, a little drifting there is fine. With my sticking throttle cable I had braking problems (blipping, engine pushing forward rather than adding braking) so I can't comment on the braking into 10a.

I think they are better than the Michelins when not yet up to temperature. The Michelins are NASTY when cold- they will snap you right into the wall. The Hoosiers seem to be much more predictable. I was able to pull steadily away from Chris Musante on the first several laps, but then when we both had warm tires he could catch me.

In our GT3 cup size, they are $1560 a set, a huge savings over the Michelins and even over the Yokos. The savings on them allowed me to rent a Hertz Corvette ZHZ for the weekend instead of a Subaru, well worth it!!

 

I use Pirelli slicks and love them. My GT3 is like a different car... the only issue I had was that they have so much grip that they seem to turn on the rims ! I made some marks to make sure they were not moving on my Fiske 18" wheels and actually they turn quite a lot.

Any solution to resolve the issue ?

 

Every Hoosier and Michelin I have used has spun on the rims. Hoosiers were the worst of the two. I tried dimpling the bead area and when that didn't work I tried taking a small chisel and making a little raised chard of aluminum in both directions. This helped a little but they still moved. Mounting them without using any lube can help a little also. I just stopped even having the Hoosiers balanced. that helped also.

Mike, I remember reading your post earlier maybe on another thread. Sorry I asked a question you had already asked. Thanks for the comparison. I don't like tail happy either.

 

I hope someone have a solution because I can't make more than 3 or 4 laps before my wheels get unbalanced and my car starting to shake like craky in the fast straights !

 

Peal off all the weights. They just magnify the problem when the tire moves. I don't think there is a danger factor involved in the shaking---just a nuisance one.
