I have made progress with reducing the effect with tire pressure (36 psi all around) but a post on the 3 series board said that the M3 had a much reduced tramlining effect due to a different caster angle as opposed to base level 3 series. BMP sells adjustment plates that allow for an adjustment in camber and caster angle. Has anyone running a Plus 2 conversion used these adjustment plates and have they helped reduce the tramlining effect? Are these the same thing as the mounts shown in the Bentleys manual? They sure look the same. If anyone has used these to reduce tramlining please let me know. Much thanks. Karl
