I’m building a track lip (2.5" off the ground, removable), wing and underbody tray for my S2k. Got a start today. Decided to start with the lip as a warm-up, since I’m a little rusty working with composites and mounting the wing will require far more forethought.
Started by tracing out the existing lip (4.5” clearance)
After that I did the same for the corners, and sanded them both down.I’m planning to lay the kevlar tomorrow, cut to shape, and fit. I’ll also be repairing the existing lip but that’ll require some warmer weather. Here’s two pieces mocked up:
Kevlar seemed like a good choice for the two lip kits, due to the resilience. The wing will be a CR-type design with a low AOA in the center... I’ll probably use carbon fiber for that since it’s more rigid than Kevlar or glass. Not sure on underbody tray... that’ll take a lot more research.

The hypermilers like to run coroplast undertrays.

Wow that stuff is super cheap! Thanks for the heads up! Will make a great sandwich material, lay a single carbon layer on each side, should be perfect!

If you want sticker shock go look up large sheets of kydex, its a thermoplastic used in a lot of sports gear.

Expensive... have had that stuff around before. I’ll stick with the cheaper carbon weave...

If you are looking at coroplast, make sure you layer it with alternating grains as it behaves very much like cardboard. The good news is a fine tooth saw blade can cut through it with minimal deformation or melting.
