I have this same set of coil overs... and have been toying with these for a while... Be REAL careful when ya put these on William. The spring rates are good, but placing the collars is a bit of a pain in the ass to get ride height correct. My first attempt ended when I let the car off the jacks, and the oil pan of the car ended up 3/4 of an inch from the ground. I can;t attest to how the ride or handle yet, as I don't have a running Supra yet (thats a whole other post).. but they fit nicely.williamb82 said:well, the drop zone coilovers i got look identical to the ground control ones and they even use an allen bolt to lock them like the gc units instead of 2 collars betted together. im not worried about the fabrication as im going to be doing more then just a coilover setup on the front. heres a link to some pics of the ones i have.
