After 3 long Golf free years (previously owned mk3 GTI 8v & mk2 GTI 16v) I've returned to Golf ownership with a GT TDI 150 that I picked up today. Very pleased with it so far, 90k, FVWSH, 3dr, only problem it's in boring old silver

Needs a service and MOT so won't fully know what I've bought until next week, it will deffo need new wishbones (or just bushes?) but I don't think there's any other serious problems with it. (until the notorious chocolate cam says hello)
Compared to the Leon Cupra T that it's replaced I'm finding the handling a bit 'soggy' (I know this is a mk4 trait), any tips on tightening things up a little and making it handle like a proper GTI? (without lowering it though).
