fitting ~ £100 if you can get it done locally; geometry is normally around £40 (you need full 4 wheel, not just from wheel tracking)
now; completely going back on what I have said - the 1.8t lump shares aftermarket springs with the 1.9tdi, and not the lesser petrol engines! so I take back what I said about them fitting well; they would fit, but you would have the incorrect weight suspended on them which would reduce handling ability; and could cause the front end to be dangerously bouncy (i'm glad i checked now!)
If you look on DPM's site you could get a set of Koni springs with 35mm drop for £95, so that is probably your better option! Sorry for bullsh1tting prior to this post
