I've always been paranoid about getting rear-ended in the miata (small car + low lights + idiots constantly staring at their phones while driving), so I bought a third brake light pulser to help reduce my chances of being hit.
My steering column had a lot of play and always clunked, so I got a new lower intermediate shaft and adjusted the steering rack slack. Helped a lot but I need a new rack for sure.
Got an Odyssey PC680 battery to cut a little bit of weight and relocated it to the center of the trunk, side mounted in the "spare tire area" that's not actually where the spare tire goes. Made a custom mount too :).
Other little items... dash is bolted in and the tombstone block off plate finished, put the passenger cowl thing back in, made a hood release bracket from a cut up cruise control bracket, cleaned the tar off the door panels, painted the valve cover wrinkle black, new valve cover gasket, painted the header heat shield black, new PCV valve and grommet, and new valve cover vacuum lines.
I'll post some photos of the finished car after its aligned and washed.
