And here's what it looks like in "mid-fold" in case there was any confusion.

I am debating about banking those corners. The 1/8" hardboard is quite flexible, and I could easily get a 1" bank and add a guardrail without hindering its ability to fold. Although, you get some great drift at speed on the flat black spray paint, so I might leave it flat. Oddly enough, it's still quite grippy though driftable. It's a great driving surface.

Well, either way, the final step will be painting it so it doesn't look plywood.
