So I installed Tein Springs on my Stock 04 TL Shocks. The car rides nice and is smooth but when ever I hit a whole or a bump the rear end feels like its going to loose control / Dance from side to side / not stable. This is annoying me, anyone know what could be causing this?

 

My car does the same but it's from my rear shocks being blown lol Maybe yours are getting close?

 

With the stock shocks I'd say that the shocks bottom out when a sharp bump is encountered and it won't be long before you need replacement units.
Should do it right the first time, springs and shocks as a unit.

 

Ok, so you guys defiantly think that its my shocks that is causing for this to happen? If thats the problem than should I keep my springs and buy new Tein / Koni Shocks or should I just buy the entire new set up shock and new springs?
