Mazda MX5 DAMD Body Kit
DAMD! That's a mean looking Miata. DAMD makes some of the most original, strange / evil looking aero parts. Check out the 3/4 view of the red Miata body kit , the DAMD (Austin Martin style) front bumper actually looks pretty good on the Miata. If you like that type of look , check out DAMD's 350Z. For some reason I feel like the classic styling of the DAMD kit might clash with carbon fiber parts like a Miata carbon fiber hood, so you might want to with a painted 1 color look if you pursue this route.

I wasn't much of a fan of the new enclosed headlight design of the latest MX5 front bumper, but somehow this AutoExe body kit changed my mind. It looks great, just compare the front end to a stock MX5. Let's see more aero parts for the Miata
