I run in the wild wild west so there are no CAMS classes unless you are doing circuit racing. I run in a supposedly road registered class in which case I don't run the wing at all, just a front splitter, although my car is becoming less and less suitable for that class. I was thinking of moving to the outright class so I can continue developing the aero on my car and run Hoosiers... you can see the profile here:
Ideally I should be in CAMS 2B I think. Which has a few more restrictions on rear aero than 3D. It doesn't really matter unless I head over east for an event.
My wing sort of complies with 2B but I think it sits too high (ie more than 300mm). It has a 250 chord width but it probably looks a bit bigger in that photo due to the wide lens. And yes I didn't intend to do the cut-outs, at the time I was making this wing, I was a little focused on weight savings so I drew the cutouts as an option but didn't think the support would be strong enough. I think when I sent the CAD file the cutouts were hidden but the CNC software unhides everything before cutting. I've since learnt to clean up all my files before sending them off.
I'm getting them redone now as a solid piece, along with a couple of other bits and pieces. I was thinking of also going a couple of mm thicker in the material and then machining down the bottom where it slots between the body and the boot.
