Ground Control are fake coilovers, they fit over the strut and shock, if you are going to sped the money just wait until, a full coilover is made and there are many in the works, such as HR's and many other coilover companies. I've heard many shops are looking for test cars for many different applications. If anyone one is down to give there mp3 up for a period of time. Im scared to let someone **** with my MP3. but if your dow call around, you might find someone, to hook it up. for a fraction of the cost.
