So after driving my M05 and V2, had some time to spare so pulled out my old M03 and balanced the car left to right by shifting the sport pack battery towards the right of the car (away from the motor).
I used some left over M05 battery tie downs plus two 3mm? spacers as I did on my M05 to balance left to right. 100% better driving now.
Hahaha
Will play with the springs and dampers to finish it off tomorrow.
