After the diffusers were mounted, construction for the splitter frame started. The frame for your splitter is extremely critical as a splitter falling off while you take a high-speed turn could be a life and death situation. The frame needs to be strong and mounted where loads are highest. In our case, the loads are going to be the greatest right in front of the air dam and the leading edge of the diffusers. We used aluminum bolted, riveted, and bonded to the splitter with joints overlapping where possible. Two spurs are added to keep the splitter from flexing and to give us additional mounting locations.
