hopefully a functional diffuser

This is cool, but I gotta ask...how do you keep the diff cool? This looks like it'd trap heat in the rear end, eventually cooking gear oil and the diff.

I had the chance to try and test the diffuser in the last leg of our Miata Cup.

It may have contributed somehow to bringing down lap times coz in Leg 1 best time was 2:59.965 while in Leg 3 best time was 2:45.053 SAME TRACK. No other mods installed between races except with the addition of this diffuser.

I have a hard time thinking the diffuser could drop 14 seconds from your lap time or am I misunderstanding something?

that looks really hot, but a functional diffuser needs a flat underbody. Its against physics if this thing works. But it looks damn hot indeed
