B&G autobahns makes the SVT or contour sit the best in my opinion and perform just as well as H&R. I've had eibach/H&R and B&G.. B&G were the best in my opinion..

Eibachs were softer than the stock springs in my opinion...

B&G= even across the board stance
Eibach= too low in the rear
H&R= too high in the rear
