Quick question, whats the difference between club pro and pro? They both seem pretty wild classes. Also, TA looks like a great way of eating some jap crap (I like them really) on various different circuits. I love time attack, the whole, pretty much anything goes with the wild aerodynamics and mad engines. Gotta love it, and good luck to whoever enters next years TA.
