Have spoken to Phil at Driftworks, about the possibility of a group buy.
These are the coilovers in question, http://cgi.ebay.co.uk/HSD-Coilovers-for-Le...A1%7C240%3A1318
They are available in either normal (more for track use) or smooth (more for daily use.) £685 is already a great price (especially when compared to Tein) considering they are European made, have mono-tube dampers and come with pillowball top mounts (equivalent spec Tein's would be £1200+)
Discounts available for 4+ buys, 8+ buys or 12+ buys. I just want to gather intrest so I can finalise some prices. Would be looking at ordering them for around the middle of April.
