I did a lot of research when completing the alignment on my car. Goal was that it had to be streetable and not too twitchy but have an aggressive turn in when going into corners. Here is what I ended up with and am currently running:
1/16" Front Toe in
1/4" rear toe in -- important for off throttle stability!
3 deg caster
2.5 deg neg front camber
2 deg neg rear camber
To me Dean's specs are very mild and the 510 responds well to more caster and camber.
