s007a is crap.. supposed to be the RE-11 replacement, it is NOT. 5 people tried to kill the very used RE-11s I got on some OZ wheels (I wanted lighter wheels..), I sold those wheels with the RE-11s still on, and told the guy that bought them they probably have a few weekends left, he looked shocked, then I gave him the history of the tires since I got them. TT-D champion 2010 borrowed them when not doing TT (RA, CMP, RRR), another buddy (every session all weekend at RA..every..session), me beating hell out them.. Those were good tires, the s007a, shit. One AMP weekend, done (really just one day..). Not impressed at all.
