I am hoping that someone has tried this combo. I searched, but couldn't pull up anything. Tried Yahoo and found some other interesting info. I have had the sportlines on the ITR before with the OEM dampers, and didn't like it. I think that it might have been the shitty progress camber correction kit I used up front, that gave it the crappy handling. I found that the sportline spring rates are close to that of the H&R sport springs, and I have heard some coments on that set up. Is their a linear or progresive difference between the Eibach and H&R's? I still have the Eibachs, so my cheap *** is trying to save a buck by using them.
