      Look at post #11 (by Jon A) in this thread. Your roll steer % is the slope of dotted line AB identified as 'roll axis'. Downward sloping toward the front of the vehicle is vehicle roll understeer.



      Just to try to ward off the confusion that this picture from Millikens' RCVD may be bringing with respect to terminology, the 'roll axis' in this picture is the rear suspension's own roll axis, not the roll axis of the vehicle as a whole (Milliken refers to the vehicle roll axis as "Neutral Roll Axis", probably to provide some distinction between the two).

      Norm
      '08 GT coupe, 5M, suspension unstockish (the occasional track toy)
      '19 WRX, Turbo-H4/6M (the family sedan . . . seriously)
      Gone but not forgotten dep't:
      '01 Maxima 20AE 5M, '10 LGT 6M, '95 626, V6/5M; '79 Malibu, V8/4M-5M; '87 Maxima, V6/5M; '72 Pinto, I4/4M; '64 Dodge V8/3A
