I'd go with Phil's numbers, they're pretty decent although I'd personally run with a bit more toe out at the front (5deg either side), but that really is just my preference. That's a really solid base to work from to figure out what you're after, thanks for posting Phil
What settings do you run your BCs at, Adab? I had a play with some on a Zed recently, I think I settled around 10 from hard on the front and 14 from hard on the rear, but that was for road use. I'll have to check on those numbers, but I think they were around there.
