Since I'm a DIY kind of guy, I asked my friend to help me out so I could save the $200 or so on installation...hell, I've installed everything else on my car! He's had experience with installing springs/coilovers before, so I trusted him. Well, I should have just done it myself. He ended up blowing one of my front shocks by . The car rode like crap...had HORRIBLE "bounce" everytime I hit a bump.

I bought 2 used front shocks from VIP and replaced them myself. I know I did it correctly...BUT the car still rides like crap. It's not nearly as bad as before, but is very noticeable. So either A) the shocks I bought from VIP were blown, which I highly doubt or B) the springs are screwed.

Any ideas guys? I think I'm just going to get some coilovers now because everytime I drive my car, all I do is pay attention to the bounce and it's so damn frustrating
