I had Sumitumos, even with 315/35-17 they still can't hook at all, in the rain it's almost as bad as a bald drag radial. Had Nitto 555Rs w/ 315/35-17 DRs in back, they're okay, but on the strip they suck, rain is actually decent. Had Toyo T1-S on the 240, they're were just like a regular ole tire wasn't too happy for what I paid for them. Figured the T1-R would be alot better I tried them, they're good on the dry, but suck arse in the rain. I now have 275/35-18s up front and 295/35-18s rear... BFG KDW IIs G-Force, they're by far the best HP street tire for all around, and the best in the rain.
I cut 1.9 0-60 on the track too, but they still spin like hell on the track.
