S-03's are very impressive in the rain. they're also good when it's dry. they are also expensive and every time i go to the track i have to suck it up and do a 1-2 second burnout. seeing the smoke blow away is like watching money fly away...

Pilot Sports are also very good. they are also an expensive tire.

i went through 2 sets of Yokahoma AVS Intermediates, before they were discontinued... they were awful in the rain, but they were very stable in corners although straight line traction wasn't that great.
