A few month back I started to look into solutions to eliminate the factory hardware for the rear diffuser and to remove all flexing and deflection. I think I finally found the final version of it. After looking for existing attachments points, it hit me. The transaxle is a fixed point in space, is strong and has plenty of hubs which are pre drilled and threaded. The casing will absorb the downforce, I have no worries there. All I can say that the diffuser does not move anymore, in any direction and is absolutely symmetrical and straight (took some massaging...). All dimensions were double checked and measured across the rear chassis. I also think its pretty too without the usage of massive hardware obstructing the view, taking the attention from other major components away. I chose 5/8 steel tubing with 1/8 wall and M12 bolts welded to a slanted bracket with 4mm material thickness. The clamping force is incredible. I installed the wing uprights because I needed to check for interference. I found that I still having 2mm between the passenger side upright and the closest bolt of the transaxle. The gussets are made from 3mm 6061-T6 and I continued stitch welding a la factory from the underside.
