The Kumamoto Sports Factory rear wing is virtually identical to the Mazdaspeed Aero II. I wonder what connection there might be?
MS Aero II
Kumamoto Sports Factory
Per your request
One of JoeyB's friends
Dale's MX-5
Not MS yellow demo car. This one is from Joyfast.
Joyfast race car appears similar to MS but end plates look more thick.
From the Mazdaspeed catalog
I'm sure if I bothered to keep looking I could find more pics. I checked
Carview but didn't see anything under Aero Parts section.
P.S. Phatty, I just realized how closely your old car Booger looks like the GV demo car with those black fender stripes
