well you u still have to get them mounted and stuff, so might as well stick with discount....

keep us updated when you get them, Im really considering going with this tire..

 

Michelin Pilot Sport IIs... They make many in 20 (including 335/30 YR20 and 345/xx YR20) and have a AA traction rating.

 

From what the vette guys say GS-D3's better than the Pilot Sports, but those are run flat versions. 345's a little wide for my rims too. I don't think you could run much of a drop with them either. I look into them, but Michelin is a little expenssive for my tastes.
