Anyway, on 60's it appeared that the 4 corner wheel's are toe'd in a bit. I was wondering what is the effect of/ reasoning for this and how does it affect the chain/sprocket alignment? Thanks.

Yea thats why they have the 6 wheel caster driver just like 25 last year. They have an offset for the center wheels a little lower then the front and back wheels. so the front and back are pretty much like a powered caster. It tips over on to either front or back generally depending on the direction its driving in. This allows them to have a great turning radius.
