Spliiter end plates

The splitter is not allowed to extend beyond the bodywork so to make it more effective, an end plate is added to keep air from spilling over the side of the splitter.

I started with making a template out of construction paper

Then transfered the shape to aluminum and cut it out with the plasma cutter

With a tab bent under and behind the endplate, I could rivet it to the splitter and bolt it to the spoiler for easy removal
