OK.. finally made my mind up, i'm going with the Bilstein dampers

Now i'm trying to decide what springs to fit and who will do the job. I've noticed that most people either use whiteline or lovell superlows in conjunction with Bilstein dampers. Any particular reason for this? The Bilstein distributor informed me that i could also use my current sportsryder springs as the new dampers will be cut and the saddles set to suit a particular spring (to achieve the desired ride height). Does anyone have experience with these spings when fitted to Bilsteins?

Additionally, is there any workshop in particular (in Melb) that people would recommend to get these things fitted?

Cheers,
Anth
