Sweet. It looks like your rear undertray/diffuser completely encloses the bottom of your car from the gas tank back to the bumper. Nice job! If you run into any heat issues, please let us know.
Have you thought about running more strakes to smooth the turbulent airflow? More strakes = more downforce = smoother air flow as the diffuser airflow combines with the airflow behind the car. That's as I understand it anyway.

Thanks! Always working on her it seems..thankfully I'll never be done:wink:
I have two additional strakes that line up with the two rows of button heads, just not yet sure on the aerodynamics. I've read that a slight (up to 7 degree) toe in for the strakes is better than straight parallel. As far as heat, note an issue yet in this cool weather. I ran version 1 (which was only 26 inches deep) without heat issues this summer. This current one is 12 inches deeper. More pics:
