the more i think about it.. i actually think rubber TC is more effected by traction compounds (and track conditions) than pan cars with good tires (i.e. 1/12th... and not hard spec wgt tires). prior to vegas i practiced at a big but dirty track. my 1/12th scale felt great there although it was sprung really heavy.. such that i could of never driven it like that at IIC. on the other had my touring cars were complete piles spinning out under acceleration.
