Elon   Caster when turned creats a diagonal weight bias ie right turn loads r.f 
and l.r. very bad with a locked rear end!Wheels steer best when all four both 
touch the ground equally"lsr." Weight on front wheels steering. weight on rear 
wheels traction, weight in the middle a deficit. Note how little steering it 
takes to change lanes at 60mph! A lot of caster = steer-correct- 
steer-correct-steer-spin! A lot of castor would work good rock climbing!    jack

I thought caster had a self-centering effect?  Are you saying putting as much 
weight through the center of the contact patch is better than the 
caster-effect?  IOW, caster moves the weight forward of the contact patch. . 
. and that is not good?  Very interesting, Jack :-)

Minimal caster might help. Jack

That is a good point, Jack. But on a car as long as yours the rate of spin is 
not that same as a 98 Monza.   The length of wheel base slows things down as 
well, so I am wondering if polar moment is as critical as it would be on a 98 
car?  -Elon

Hi Elon   Skaters--arms out,slow spin, arms in, fast spin. Jack
