I've driven a Miata on a race track without a roll bar. We all make choices. Sometimes they're not the best choices, but we make them.

Double-hoop roll bars must fasten properly to the chassis/unibody as
required by Appendix C, particularly at attachment points in the center
of the car.

Seems like you left a lot of shiny metal to rust again over the length of your build. Is that going to be an issue or did you go back and coat all those bare welds and metal?

Only concerned if I'm working the course that day. Otherwise you can live with 300+HP in 1800 lbs. No one else has that ratio except maybe Howard? Not the "Duck".
