I autocross. Everyone recommended Dunlop Direzza Star Specs for 18" wheels, but they don't make it for 19". Other tire I was told to get is the Hankook Ventus R-S3 (the big daddy of street summer tires by Hankook. Stay away from V10s) - which comes in staggered OEM sizes. (staggered means different tire size in front than in back).
I am ordering some today from Alex at Tirerack and should be here in a few days!
Hankook*Ventus R-S3
These tires are going to stick like glue after break-in and I don't need to modify any spacers or roll fenders or anything. Staying in stock. (Road Tire RWD class... graduating myself out of novice next time)
