chers for the heads up Lewy.
http://www.vwgolfmk2.co.uk/viewtopic.php?f=14&t=13549I recon the accuair management with the ride height sensors would be epic on the track mixed with airlift struts (damp rate adjustable)
Downside to ride height sensors and accuair - You need to drill into the chassis for the sensors (not my cuppa)
Me and Lewy have tested out an Airlift kitted mk2 recently. I now think all static suspension is rubbish put it that way

Comfy? - VERY. I dont look forward to drive the mk2 anymore as the coilies are back breaking
Prices are from £1500-ish for a setup with manual valves and about £2300 for digital setup. Digital takes the guess work out of how high and even you are rolling.
Fitting anywhere from £500 to £1500 (If you can wire a stereo and change suspension then you can fit air ride in a day)
Not looking to make a show worthy boot install when I get mine next year but hope to hide the pump and ugly air tank
