hard front and soft rear? do you lower the height of the

Honestly there is nothing you can do besides accept the fact that LB is not for high speed cornerings... Perhaps you should consider other choices like a buggy or even a on-road car........
Tamiya does make oil shocks for LB but they are useless in my opinion....
Recall there were a post about a week ago: there is a guy in US modified LB and even running brushless system. He did modified to his LB to 6角形 adapter. Try search older post...
