anyone knows good shop that can put springs/shocks to my car? I live in seattle area.

and, how much is the reasonable price for putting them on?

thanks

 

Assuming that you are talking about after-market springs and shocks, if I were doing it and my car was in warranty, then I'd have my BMW dealer do the installation after receiving its blessings on the parts. The dealer's blessings and installation might not mean much warranty-wise, but they are the best thing you can get under the circumstances-----unless your part manufacutrer provides an after-market warranty that covers problems with BMW parts that might be blamed on the after-market parts or their installation.
