Speaking of the o-ring mod, has anybody tried at Hara-spec upper deck on carpet?
I'm currently using a BMI 3mm main chassis and upperdeck on my carpet Pro4, but I usually have a tweak problem after a slight tap on the boards. Usually it not too bad and I can just drive around it (albiet more slowly!), but it is still annoying to have to re-set my car in the pits after every tap-o-the-boards.
I know the general idea behind the Hara spec upper deck is for lateral flex, but will this flex do more hurt than help on carpet?
