i just picked up my turbo cab form having the pss9's installed last night, in the short drive home they felt great, it felt like a new car, i waited 2 1/2 weeks for an appointment with a reputable shop her in MA, and the car took 4 days, i know they weren't working on it the whole time, roughly 8hrs for turbo install and oil change, but i am very happy with the results!

 

Supposedly there are differences in the shocks....Ones for the US and ones for the rest of the world....but I doubt it. The difference is, US Bilstein wont warranty a rest of world part number.

 

There are a number of different set-ups for the PSS9s. I got mine from FVD (Euro version) and they are quite a bit different in terms of spring tension and length. I love them!
