I really don't have an update. The car generally stays in the back of my mind. Espescially this past week since I was focusing on some testing to get into graduate school and my birthday was on Friday.

Although, since the new CAM rules came out, I was thinking of new, composite aero ideas since the front spoiler and rear diffuser don't have to be within the constraints of the bumper on "non-integral" bumper cars. I'm sure it would help on a race track, but I don't know how well they'd help on a low speed autocross.

To get any significant aero forces below 50mph your spoiler would have to be the size of a garage door. Pretty much useless for an autoX. Won't hurt anything, but it won't help much either. You might see some minor cooling benefits if your front spoiler is directing more air into the radiator instead of letting it go under the car, but you're not going to see any significant downforce.

Road course is a different story. Typically aero doesn't start to a become significant handling issue until you're talking about sustained speeds over 75-80mph. At least if you're talking about downforce and drag.
