I haven't seen any rear diffuser for the miatas...why?
The only one I found is the one in the picture (isn't it awesome?)
Anyway it seems like a custom job and it is from a German mx-5...

The reason you don't see many is because most Roadsters can't go fast enough to benefit from one. Plus to be really effective they must be designed as part of a complete aerodynamic package including a flat floor. While many Roadster enthusiasts seem to value function over form there still is a large number of folks who value purely cosmetic body modifications.

and a lot of those cosmetic conscious roadster enthusiasts are on this board, lol.

i've seen a fair share of roadsters that can benefit from a diffuser. and it would even help with regualr highway driving at 60+ mph.

it'll probably be a year or two, but i plan on making myself one out of sheetmetal, including covering the whole underbod with louvered panels.
