How old are the KYB's ? have you really ever messed with them before ?

Okay, let me re phrase.. if you had not had the shop install the other stuff, would you have ever noticed this problem? and if in fact it started shortly after the drop, maybe the shop is responsible..

Shoulda just done it your self IMO, I mean, it is not hard at all, and you gain the know how.. Then if something f***s up, you can just re trace your steps.. There are more than enough rescources on here, and many other forums to assist you.

I did mine over the coarse of 2 days, and I work 50+ hrs a week, and have a VERY small drive way.. So there really is no excuse or reason to NOT do your own mods. Especially such easy ones as this..

Sorry if this was not helpful, But thats all I could offer.. bring it up to the shop, see what they say, and learn from it.. Next time, D I Y.

::Edit:: You live in california, I am sure there are a million and one other tuners around who will be willing to help you do this stuff, as long as you dont try n get them to do it all 4 u.
