I know a few of you have been waiting for this review.... well I have had the Corsas for a a few mths..... 2 events and about 400 miles on the street... I can tell you.... this is not a street tire.... ride like crap and follow the road... not like a little drift.... more like hang on... you will be driving with 2 hands all the time..... that said..... these tires ROCK.... once you hit the track... the turn in and grip is so far beyond street tires .... it's not even funny.... after a few adjustments on the Z ... my 2nd event this year was very very fast I beat people that I never thought I would beat.... .5 sec slower than Shelby Cobra replicas and over 2.5sec faster than the closest E46 M3
