Okay guys I got my car lowered and a front camber kit installed on my car. I have had my TEIN Type Flex Coilovers for about six months now with no problem. I installed my SPC Balljoint front camber kit in my car about a week ago and the only problem I had was the balljoints hitting the top of the fender when I would run over large potholes. Well now, just yesterday my car is doing something else. This is after I have had my balljoints for a week with no problems... By cars steering is very unresponsive. Like, I will go to turn my wheel left and right really fast to test how responsive it is and it's like there is a delayed steering. As I drove it on the interstate and tried switching lanes fast, there was a huge delay in the steering! Like I turned the wheel and like a fraction of a second later the car would then switch lanes and it didn't feel very stiff. It didn't used to do this before so I don't know what the deal is. It feels like I don't even have coilovers installed anymore. Well anyway I took it in to get an alignment done and to get my camber corrected and all that jazz. After they were finished they told me everything was rock solid under my car and that they couldn't point out anything wrong. They drove it afterword and told me that they did notice that problem I am having. So basically the shop didn't know what this steering problem is and they claim everything is just fine with my parts. Does ANYONE here know what my problem could be???

Thanks in advance,
Matt
