With fiberglass being reasonably light, strong, inexpensive and reasonably repairable. I've never worked carbon fiber because I can't make fiberglass pretty enough to show off the weave and never needed that type of weight reduction.

I have a test in mind once the car is back on the road to see if the splitter would stay up at speed. After track testing various configurations of the splitter and deciding whether rigid supports are necessary on a size/design I'm happy with I'll make much lighter ones. Since the time I made the splitter I've had the opportunity to do some tuft testing on another car with the same body, ride height, tire sizes etc. I'll discuss more later on in the thread but here's a pic at highway speed, note all the tufts below the grill openings pointing straight down. Leads me to believe there will be enough pressure on the splitter to push it back down if it gets bumped up, but testing will be the best way to find out.
