Seeing your hood I think has made me change my mind. I was planning on cutout out the front vents like you have an placing a Gurney flap in front of them. After seeing your drop vent I think I'll make that instead. How far down is vent?

I was thinking of playing with a speed brake that would be about 50"x4". It would sit under the wing, extend 3" and be flush with the trunk lid. During braking a linear actuator will push the speed brake up (to about 60-80 deg) and once the car gets under 15 mph the brake will go down.

I remember back a few years ago that Vic Sias was developing one on his SM M3. He showed up to the Solo Nationals with it, but it was disallowed (he had to run it in a fixed position). People where saying it would be too expensive to run, but IIRC the pricing was less than what Eric Strelniks is rumored to paid for is dual element carbon wing.

Because anything like that would quickly be protested away, nobody has taken the time to develop a big, multielement version at an affordable price. Because there isn't an affordable one, nobody is petitiong the SEB to allow them. Back to chicken.

Well part of the problem is that the rules state you can only have 2 wing elements. His wing was considered 2 elements. He was also within the maximum size allowance. I think he tried to stay within the rules of the time. I think now its written in that active aero is expressing prohibited.

Does QLD's "Lightning Composites" have anything to do with an Aussie member of ours with a similar name? The one building CF race Miatas?
Unrelated: I'm also wondering a bit about the wisdom of dumping air into the diffuser. I think it'd be better to dump it into the wake above the diffuser.
