Most people get them self H&R (coil-overs, or PCS) or K&W (var 3), because H&R PCS is the same kit as Bilstain PSS9 witch gets out of order in something like 10 000 km (2 of my friends who bought them, are very disappointed with that fact ) buy the way H&R stopped the production of PCS you can only get PSS9(absolutely the same) and H&R coil-overs are not rebound adjustable. About K&W var. 3, because i got big AP-racing brake kit i heard that there were difficulties fitting the rear dampers, plus the front dampers are noisy ("knocking sound", that’s what I have been told buy a person who uses them on RS4). Then I decided to get my self a AST suspension, i will be the first one to get it on rs4 heard many positive comments from AST owners. So if some one knows something about AST i will be very interested to hear your opinions.Its a young Brand, so the should work on quality very seriously
And now the question is KW Variant2 or Variant 3, people who use Variant 3 say that they adjusted it only once so Variant 2 is more reasonable? will be grateful for any comments.
