Hi everyone. I've been reading some threads here and searching the web about this. I'm thinking about getting the Bilstein B16 PSS9 kit for my S3 8L , love the brand because of his competition pedigree and NÃ¼rburgring testing , but it appears there are some issues with the rear springs. When installed they stay fully compressed and the coils rub and began to rust. It appears to be a design flaw. Installed properly (no problems here) "barrel" design Fully compressed and rusty. As far as i know a lot of costumers reported this and Bilstein made a version 2 of the springs. Version 2 (look a lot better) :thumbsup: Searching the web you can see pictures of the kit with either springs Other brand that i'm considering is K&W. I ask all S3 8L / TT MK1 that have this kit or others (K&W , H&R , Koni , etc) , to give your feedback and experiences so we can desmistify this subject and help me and future tuners to "give their babies" nothing but the best. Cheers and drive safe.
