Thanks for your comments dragonracing. I had the 2013 car and delivered good results at club level. However, I ran the 2015 car indoors with a close setting to the 2013 car and it was way out. As you say, different animal. After some advice from Henrick Heitcsh with my comments about the car having wild on-power steering he pointed me into a better direction, despite not even having the new car!
I understand now that the lower roll centres all round at 0.5mm simply doesnt work on low-med grip carpet., despite it working with the older car on short shocks.
