I got the Eibach pro kit 1.8 all around, and really like it. The ride is a little ruffer but the handleing is a good 50% better. Can't wait to get new swaybars and bushings, it'll be like riding in a F1.
I have heard that tein springs are just as good, maybe better because they are cheaper. I paid 215.00 for the Pro kit but I think you can get the same drop form Tein for 170.00. And not to step on any toes but when I called about the Goldlines the sales man told me the Eibach were better, thats why I bought them. And no he didn't sell Eibach, thats why I beleived him.
