let me show you some pics of what kind of springs i went through. =)
First set is Eibach Pro Kit. No difference in drop. Lol
The rear is eibach, the front is eibach with 2 coils cut.
Vogtland Front and rear. These springs were for the v6 models.
Vogtland rear with cut oem 4th gen front springs.
Oem 4th gen front and rear springs, cut 2.5 coils off.
Dropzone springs front and rear.
Dropzone rears with oem 3rd gen front cut springs. i believe 3-4 coils were cut. Best looking combination if you are going for looks. =)
All in all, my conclusion is, if you wanna do it right, go with coilovers, if you aint got the money, do it the ghetto style. =)
