One thing that is a great measure of driver performance, chassis changes, and overall vehicle speed is minimum corner speeds (vMin). Maximum corner speeds (vMax) are a similar measure and they also show a great amount about engine health, aerodynamic changes, and more.
Some software packages pull this info out automatically, but AiM Race Studio 2 Analysis is not one of those packages. But, with the math channel package I put together you can have it automatically displayed in a channel report.

The video explains it all, but the basic idea is to define the corner distance, then take the minimum speed of that defined distance. The video explains it all in more detail and will get you started on another way to measure your performance.
