Reply to "My Solution for CMC Butt Sag"

Had the same issue with my CMC widebody. I jacked the rear of the body up until I got nice gaps on the doors. I then drilled and tapped the subframe along the sides of engine bay and also along the back. I made up two fibreglass mounting tabs for the back portion of the subframe and bonded them to the body and then ran bolts along sides and on rear mounts into the predrilled and tapped holes. Next I welded brackets to the underside of the subframe and to the frame horns on the chassis and installed two 1" square tubing to tie the subframe and frame horns together. Maybe a little bit overkill but it eliminated body sag and also took the twisting out of frame horns that you can get under hard acceleration.DSC_1284DSC_1283DSC_1280DSC_1277
