@psosa @mcmirandePablo, Marcos, thanks for dropping by and thank you for your comments! It really helps motivate me to continue my work on this.
I have a few people onboard, but I'm happy for you to be a part of the test team as well. I'm currently in the process of fine tuning the final aspects of the tyre physics and will be releasing a tech demo sometime soon. If things go as planned, the tech demo will include one or two little surprises.

It's not widely publicised, no. Around a dozen or so GPL'ers know about it. I kindly request that you don't post about it publicly on SRMZ yet, but if you have any friends over there (non-mod team), feel free to PM them and direct them over here.

Today's update:- Found a way of changing the tyre stiffness depending on its pressure. In the original GPL, the peak slip angle can change by well over 2 degrees between 20 PSI and 26 PSI and over 3 degrees between 18 and 26 PSI. This is partly because of how much lower the tyre spring rates are at lower pressures. These differences might not sound a lot, but even one degree difference in peak slip angle is noticeable. I had noticed my tyre physics felt weird when the tyres were cold and it seems this was the cause.
