Here is something cool, I picked up this figure to pose with some of my cars, there's a few similar styles in Japan. Second hand shops have many really cheap.
Against the AE86. it's about the right size. AE86 is very big compared to say a JZX Chaser with the same wheelbase.
Scale is actually about 9th scale. Against my RX-7s it's a little big. but effective none the less. It should match the RWBs pretty well.
