straight line stability

[jaykay]

I find my the straight line stability of my 2000 S (18" 3 piece sport classics) pretty twitchy when there are disturbances, longitudintal (with the direction of travel) undulations in the pavement.

I seem to recall later model years going through changes in the rear track bars to attack this problem. Has any one fitted later model reat track bars with a good effect?

I had 15mm F and 23mm R wheel spacers on which made the car much more sure footed; perhaps they gave a favorable roll centre change; track change. I had to take them off as I was getting substantial vibrations in the steering and the seat from 110kph to 130kph+. There may a balance/manufacturing problem with them...not sure yet.
