My S3 is currently sitting on Bilstein PSS (B14) from the previous owner. I found it too low at the rear with the collapsed looking spring and I am planning to do something to it.
I usually used my car at the weekend and will drive it hard ocassionally on windy mountain roads. I find the current PSS setup acceptable to me in terms of harshness or ride quality and I am appreiciate with the firm feeling of the current setup.
With extensive search on the forum, I still can't find the conclusion. I came up with the following:
H&R + Bilstein B8 with Neuspeed 21/19 or H&R 25/21 ARB
H&R + Koni Sport Adjustable with Neuspeed 21/19 or H&R 25/21 ARB
H&R Sport Coilover
I was thinking about the PSS9 (B16) as well but learnt that it use the same collapsed looking spring as the PSS so I give-up. I would like to see which of the above setup would come close to the feeling of the PSS in terms of ride quality and handling.
Need inputs from all you guys, especially valuable comments from Ess_Three
