RE: .28 in a funfactor? oh dear....
yea its higher traction surfaces that cause me half shaft probs - ie grass and tarmac.
buggy wheels - i have been keeping an eye on the bay for a cheap set to try. gotta pull this engine to bits to check what needs doing next. there would be a massive weight saving over the tmaxx wheels, like u say, i will try them as soon as i justify more outlay...
my crx has just died on me tho, need to sort that before anything else. ill let u know re the .28 asap mate.
