Hi Poonmobile,
Depending on how well it's been maintained, you'll probably want to look into a suspension refresh.
ecstuning.com have some kits available for the Mk4 - stage 2 has the uprated TT control arm bushings rather than the standard ones.
Volkswagen Golf IV VR6 24v > Suspension > OEM > ES#248440 ECS Tuning Suspension Refresh Kit - Stage 2 - 1J0498010
Is it on coils or lowered springs or stock suspension? Might be worth looking at new springs/shocks or coilovers ...
Eibach, Neuspeed, etc. all do swaybars for the mk4 - others who have them can chime in on what they did for performance/handling.
Cheers.
