hydraulics+performance=disaster?

[adsgtn001]

My hardbody is in the shop for MAJOR repair. I guess she couldn't handle the stress of a few speed bumps. The 4link ripped off the axle among other things. So, since I'm in for a major overhaul it got me thinking... would it be a bad idea to do some performance mods on this cruiser? The guy at hot rod shop says it is. I wondered if a hardbody on hydraulics could also be customized for track, drag, drift, ect. I bought this thing already modded with hydraulics and I dunno much about these kinds of setups or even body on frame designes. But I've seen hardbodys drag and drift before so I was curious. Can she drift like a silvia but hop like an impala too?
