All of the way down, so 50 in the front and the rear. I also noticed the toe was raised in the car but i don't know if that was from the previous owner but change that to 0 on both. I could only get it up to 301 mph without a draft.
I fiddled with it on Indy, after a few laps I had mine almost off on both front and back. I was able to hit 301 on the backstretch with out a draft & 311 with draft. I think I could eek out a few more MPH w/ draft but I run out of room.
