Well heres the deal- I got a set of rims and they came with the Zenn springs for free. So I went ahead and put them on- I thought "what the hell". So now I get a few squeaks every now and then when I hit a bump and a rattley(new word) rough ride. The guy at the tire center aligned them and everything but Im worried I did something wrong since there making noise and Ive got a much rougher ride then before. So my question is did I do something wrong on the install??? My friend told me that some bolts needed to be lined up correctly or something on the tops of the struts?? Or is it just the springs are cheap???
