etam - the RA-1's are crazy grippy. They're real loud and they'll wear out in a minute, but I got them nearly for free so I couldn't turn down $640 of rubber. I haven't really had a problem with wet traction. Much better than my old Michelin XW4 truck tires
chicksdigwagons - i know a turbo would do a lot but i'm trying to keep my car super reliable. it's already got nearly 85,000 miles on it.
