Caster thoughts?

Del,

I found this article that explains caster relations in detail.http://www.motoiq.com/MagazineArtic...ur-Caster-King-Pin-Inclination-and-Scrub.aspx

It is necessary to down a few pages, then it gets to the scrub radius, wider, shorter tires increases, range of 3/4" to 3" may be acceptable.

For me it seem too much caster is hard to get, if you go to power steering, it will add some feedback. Other wise drive with a pinky finger.
