TT's are hard on uj's if you start modifying shock length, the UJ is ok with the original setup
the short gearing is very noticable , a good running TT can pick up the front end on the throttle , wich makes it amazingly capable off road.
if you can find the bodywork , modifying a florida to TT spec shouldnt be hard.
a front fork swap is not difficult, neither is a high level exhaust system.
stock rear suspension is limited , but shouldnt be a problem green laning
(i have over 100.000 miles on my modified TT)
