I had an ED30 with DSG and it was a great car on road and track. The handling mods to control it were.....
Semi slick R888's - at sensible speeds in the wet it had better grip than with normal summer tyres, in the dry they were superb.
Quaife ATB LSD - best mod you can do with a FWD.
Bilsteins B16PSS10's - adjustable and makes the car even more tractable.
Whiteline anti-lift kit - helps stop axle tramp....SUperpro version is better IMO.
ARB's - I had Autotech ARB's which really controlled the roll into corners and gave better traction out.
Fast road Geometry - an absolute must. No point in trying to drive a car without correct geometry.
Having said all this I now have a slightly modified Golf R MK6 and it still blows my mind how much better it handles the power than a FWD car. They do need more power to bring the AWD to life though.
