We've made some excellent improvments to our tires in the past few months.
Shore selection help is available from us, just try to give a more detailed report. Some softer shores may start off well, and get overheated loosing traction at the end of a run. Our softer inserts offer a wider tuning window for racers that like that too.
We often find that GT racers that understand our tire shore/inserts do best with our slicks and each track is different. Once all the variables are figured out, it very hard to find a faster product.
Ipanema tires have set many TQs, won many big races and have been on the podium at a lot of the GT races they're in.
We're always looking for good dealers in your area too.
