Input wanted on tires

[LuckyH]

I'm going to be purchasing my rears tonight. I'm having a hard time deciding between the goodyear eagle f1 supercar or the BFG KDW2's. Has anyone used these before. How did they wear? How was wet/dry weather grip? There's only a ten dollar difference between the two. The F1's tread rating are 220 and the kdw are 300. The F1's come stock on C6 vettes and GT500's correct?

F1's have slight better traction, but will wear faster.
BFG's have a little bit road noise.

What do have on the front?

Sumitomo HTR ZII are on the front now.

Doing 275/40 in front and 285/40 out back.
