It's been awhile since I've had my G8 up on the lift. I'm trying to remember why a simple plate like the one shown in the picture below couldn't be made from 1/8" plate, then a coil mount bracket welded to it?
The bottom would just be a through bolt. Then size up the factory shock (extension & compression) and buy the correct size coil over and spring?
