I fully Concur.
I drove Dans car and loved it. Wanted to buy it but couldn't.
Bilstiens Competition division is a pleasure to deal with and if
you give them your spring rates they will custom valve any of
their shocks to match.
If you use stock springs the HD's will work nicely. But if
you do go to the EuroS6 Spring Dan mentions you'll definately
want to go with the custom Valving.
I'll provide what I can for Valving Info:
DIG...DIG...SHUFFLE....5-yrs of Crud to sort through....THERE T
E-mail me privately for the Name and COntact number of the
person I spoke with. HE does valving for some of the Audi Rally
SPORT: P36-0369 - 119/107 Comp/Rebound
21.2" Extended / 17.28" Compressed
HD: P36-0370 - 113/101n Comp/Rebound
22.1" Extended / 17.28" Compressed
I BELIEVE These numbers to be accurate. I KNOW the length
numbers are correct but my writing is a little faded on the
Dampening Rates. Oddly they are Very Close. For comparison the
4kq/ur-q rear Bilstien HD is 197/47 Comp/Rebound Dampening.
Its odd to have them so close.
Anyhow, A call to the SHOP will answer any more questions you
