For as few miles as we do, I think they are a great choice. I had a couple thousand miles on mine and 6-8 races and they had great tread left until my race at El Toro. The burnout I did really cinged them and I flat spotted them a little in the speed stop challenge. I bet they will last a good 10k in street only use. The only reason I switched was due to all the events being 200 treadwears. Ideally I'd like to have a spare set of wheels with Hoosier A6's for autocross.
Those babies are like bubble gum.
