Great news!
I don't really care if bias or radial, or the compound. It will be the same for everybody.
Hoosier knows tires, and is the most reactive, adaptive, and flexible of any racing tire company providing tires to Club racers. That is why they have the lion's share of club racer business. They will take good care of us. If some other company can match their level of service, performance, and price, I am good with that too.
I hope SCCA can get this sorted ASAP, and the class can reap the benefits ASAP. Get r done!
