Decided to move house, have had to shelve my S4 plans and need to keep my 02 TDI Sport on the road.

The only trouble is that its at 75K and things seem to be going awry.

The handling is starting to feel a bit 'boaty', has anyone replaced stock A4 sport suspension before? Parts needed & cost etc?

Also I think the clutch might be having a problem as it seems to shudder/slip at a certain biting point(1700 rpm) and I noticed the other day that if, while stationary, I find the engine shudders when revving between 1500-1700rpm, before and after that range, all is fine. Could this be related?
