I recently installed a set of Koni shocks (8050-1049) and Eibach Pro-Kit lowering springs on the rear of my 2009 Challenger r/t 6spd. I had previously installed the front springs W the stock shocks and kept the rear stock to get the "old school" rake look but decided I wanted to level things out. After installation Ive noticed the handling of the car has become TERRIBLE! I experience significant wheel hop at all speeds during any form of acceleration or braking. Worst yet if I hit uneven payment the rear end shoots out sideways uncontrollably. Im currently running 255/45r20s. My question is, I was under the impression that lowering the vehicle and changing out the nivomats for after market shocks would increase the handling and drivability of the car but its decreased it significantly. The springs themselves had no writing on them but I installed them with the tight wrapped coils facing up and the shocks seemed straight forward enough. I also installed the springs by removing the rear bolt of the lower control arm and dropping the springs out so I am figuring my alignment shouldn't be off....How do I fix this!? Thanks all.
