[s-cars] Shimmy nearly gone

[Robert Myers]

The solution?  Get the wheels balanced by someone who knows what he's doing 
at my usual place.  The RF wheel was just on a balancing machine.  It was 
off by 1 ounce outer and 0.25 ounce inner lip.  This was as it was left by 
the monkey kid on Wednesday.  Pulled his weights.  Rechecked.  Now right on 
on outer lip and 1/2 ounce off on inner lip.  Added the half ounce and went 
for a drive - perfect!
