You can't go wrong with M/T slicks IMO. My last set I bought with a half dozen passes on them. And as life goes my car did not get finished for a few more years. When I replaced them in 09, Mike at Harlow tire asked if he was reading the date code correct. They had a 1995 date code. Last pass on them had a 1.41 60 ft. First pass on the new set was a 1.401 60 ft. Same tires that are on it now and they have went a best of 1.349 with the rear tires. They also do not require a big burn out either.
