I'm allowed 10" in ESP but the car is being built for NASA American Iron long term. I think I'm going to hold off and toss on a wing of sizeable cord.

We are allowed 8" from original body in CAM no wings. This is just a piece of .088 aluminum sandwiched in between my 3/16" homemade aluminum wickerbill and the original spoiler. Attached with rivnuts into the original SS spoiler. I really only use the large one for autocross and the small one for street and track stuff

I need fender flares and a front splitter still before aero on this car is good. But a splitter is not acceptable in CAM unless it doesn't stick out pat the perimeter of the body. Which is impossible with the Z front nose since the splitter on it already sticks or past the body perimeter. Plus is almost hits the ground under dive so anything under it will most likely cause it to start scraping on dive

I like to use a modified V6 fascia for the same reason it is on the COPO, it is the lightest. Without all that Z stuff we should be fine. Afterall, until you throw sparks on braking it ain't a race car ;-)

I'm partial to the yellow one, teehee.

Yeah, I follow. That rule needs to be changed, IMO. If you look at any modern front fascia design the resulting splitter is abysmal at best. Prevents us from running larger pieces like Pete's product.

There are other ways to reduce lift. Forgive me for not reading through the cam rules, but how much can you develop an undertray or hood venting? AI allows your splitter to pass up to front hub centerline.

Personally, I'm plotting GT3 levels of ducting. I feel like that's where the biggest gains are going to be within the rules for CAM/ESP/AI. Doing a front breather conversion like back in my thirdgen days. #aeromaro lol

Under tray and hood venting is unlimited. The only limits on aero in CAM are front splitter beyond the perimeter of the original body, no wings at all unless stock or equivalent and no spoilers over 8" from original body. There is nothing stopping me from putting a pan under the whole car and a good extractor in the back.

Hey Pete, we weren't aware of that. Do you know what the weight difference is?
