Tyres that were previously balling-up badly now only seem to be creating rubber particles. probably due to the tyre not sliding sideways as much.

I'd say there were at least 6 rubber compounds in use and treating the tyres before racing doesn't seem absolutely necessary as before.

Looking through lap times for these cars the hot lap time has reduced by as much as 4 tenths of a second with the majority of cars improving.

My NSR Mosler has knocked a tenth off the track lap record and every car I drove during practice was easy to push hard.
