Ok, this should be a proper V1.0 of the Slip Angle app:
http://esotic.com/media/SlipAngle_V1.0.zip
The vast majority of what makes this app cool was written by someone that posted it up to GitHub. I found it and made some adjustments (after asking for permission) so it was showing the things I was most interested in. As you are braking into the corner (brake pedal greater than 20% application) it will show you Tyre Slip. The tyre slip gets brighter purple as you slip more and more and then red when you're tires are locked up. Anytime the brake is less than 20% applied it will show you slip angle using the following rules:
slip < min_slip starts as black and becomes whiter the closer the value gets to min_slip
min_slip < slip < optimum_slip starts as medium green and becomes bright green
optimum slip < slip < max_slip starts as bright blue and fades to medium blue
max_slip < slip is bright red
"Graphically" this would look like
0 ------------- 3 | 3 --------------------------- 6.5 | 6.5 --------------------- 10 | 10 +
black to white | med green to bright green | bright blue to med blue | bright red
Generally you want to keep the slip angle in the bright green/bright blue range when taking a turn. I can't really look at this app while driving, so I mostly reference it when reviewing recorded footage (like from fraps, shadowplay, D3D Gear, etc). While driving I do notice which tires are slipping more (over/understeer) and definitely when I've gone over the line and it turns red.
These values are currently hard coded and are more suited to GT/Formula racing than street cars. At some point I/we should add some logic like the Tyre Temp app where it knows the relevant slip angles for the various tyre types and compounds.
I should probably post this app into it's own thread.
