Installed the wing yesterday (was actually pretty easy). What is the proper angle/degree for street vs. track? I have my first track day in the "new" car on the 7th at Street of Willow. Thanks!

I'd recommend you set the center section to level to start with. That's pretty close to where most people run the APR-200. With that you'll have a pretty good angle on the wing ends and won't generate too much drag.

If you look at the pic in my sig you'll see my car (yellow) is running way too much wing (I had just installed it) and Cale's car was set closer to optimal.

What rob says is a good starting point but don't feel you have to always go forward from that - you should be able to run this wing where the front end of it is higher than the rear
I was running mine at maybe -1/-2 (w/hardtop and risers) on a mainly 3rd gear track you'd probably want more like 0/+1 AOA.
Once you get to around +3 (straightedge across the main section vs the ground) its probably near stalled.

I just do mine by eye now but if you have a smartphone you can get a level app and calibrate it across the trunk section and set the angle relative to that and make notes etc.

I think with the APR data the ends of the wing are stalled at 15degrees vs the ground. So if you lay a straightedge across the end sections and work out they are near around 15 degrees vs the ground you need to be taking angle out.
