One of the things I have enjoyed about my foray into Super Touring racing with NASA is the open rule book. Building a car to a power to weight instead of the strict rules that go along with Spec racing. This has opened up many engineering possibilities and things I would like to try. One of those is replacing the rearview mirror with a rearview camera.
The little 1.6-liter engine in the NA6 Miata moves too much. This engine movement, combined with soft factory differential bushings, contributes to a lot of drivetrain movement.
The now ST6 Miata has had some serious electrical gremlins from day one. Intermittent starting issues, random fuel cuts, and erratic idling to name a few. I knew at some point I would rewire the car completely. What I didn’t anticipate however, is that I would give the rewire a first pass just days before the regional championship at Nashville Superspeedway.
I spoke about this before in Trying Not to Finish Last at NCM. Although the budget Spec Miata is a blast to drive, it will never be competitive when the expensive equipment comes out to play. That is why I have decided to move the car to Super Touring 6 (ST6). The move to ST6 will open up the rule book and allow me to build the Spec Miata to a power-to-weight limit that will closer mirror the...
