If the car is starting a yaw to the right the driver will naturally turn to
the left. Using Mayf's numbers the right rear is loaded more than the left
due to caster effect. Is this a bad thing? The upstream tire is loaded
greater than the downstream tire which would be a tendency to *not* roll the
car. If the downstream tire had a greater load applied wouldn't it want to
dig in and tend to roll the car? Is caster is a good thing?  I don't know,
but very interested your responses

----------------------------------

. . . Full left turn    RR = 900 # for an increase of 30 #

. . . Full right turn  LR = 900 # for an increase of 40 #

---------------------------------

 

Mayf: You say offset is equal on both sides. Do you mean the rear wheel base
is 9/16 wider than the front but perfectly centered in the car? 

. . . ''Off set of rear to front is approx  9/16 inches  (9/32 per side) Any


closer and I would have clearance issues. I used shade tree process to 

mount the race frame in the body so I am sure that is the error.''
