Come on Oz rather than keeping on and on about known issues, why don't you tell us about the fun you are having in your M3W.
Ian, I responded to your first comment on September, 22nd, 2017 (Chassis upgrade kit for the per 2014 M3W post #473703) politely and with the consideration due to all TM’ers.
Seeing as you have taken a second shot I feel obliged to post an update on the progress of the subject document as it relates to the M3W and what can be achieved.
I’m sure you would wish to be kept fully appraised.
