Not a whole lot you can do for radical stuff like making the car dance. But when it comes to hopping these guys FULLY wrap the frame and use telescoping drive shafts, extended and reinforced a-arms th prevent the ball joints from busting, 4 link suspensions (never really got into hopping so I'm not sure what that consists of, but I'll post pics of set ups and I'm sure you guys would be able to point out what was customized), battery placement for leverage, power balls for the rear cylinders... I'll try to see if I can get Big Tony on here, he can really disect this sort of thing..
