The preproduction car had 16" wheels, the same castings as on the production car except with a spun finish on the face.
As far as lowering the car I am looking at several options and have the attention of K-Sport and they are working on getting some hardware together for a test fitting on my car.
As far as the Miata, thanks. It is running on Ohlins DFV coilovers along with many mods to put it to the limits of the STR class for SCCA Auto-x.
As far as the aero differences you will not notice it much at all at in-town speeds. Plus they are not sticking out like roller skate wheels; the vast majority of the tire is still within the frontal bumper area. You would have to sustain higher freeway speeds to begin to maybe see a difference. And at that point a boundary layer will be coming from the nose of the car and the wheels/tires will be in a stagnant air area anyway. Not to mention the air around the wheel wells will be turbulent to start with due to a spinning wheel. If you want to truly help aerodynamics around the wheels then you need full moon covers. Aerodynamics is kind of my thing as I am an Aerospace Engineer.
There will be no camber adjustments as it is a beam axle. You would need camber bolts or adjustable lower arms in order to adjust front camber after lowering. The max camber I would want for a street car would be around 1 degree negative. I imagine that lowering it 1.5"-2" would yield a negative camber in that range or less. I will have to see once I go down that path.
