Here is data for Mr Gantman driving his Audi S4 Avant on Toyo RA1s. Heres the lap map and corner by corner analysis for Barber Motorsports Park:

Heres the min/max/avg track data. Lateral Gs are very good for the car. The corrected acceleration G is 0.18G lower (comparing GPS Accel G with Accelerometer G). The unit wasn't quite level in the front/rear direction and this causes the skew. So, the actual numbers are 0.18G lower or max braking was 0.94G and max acceleration was 0.45. So braking looks weak compared with other cars that have been tested, acceleration looks pretty good. Lateral numbers are very, very good. The error for lateral G is 0.09G so thats max left G was -1.45G and max right G was 1.55G, still big numbers.

Heres an mph graph with long G overlaid for braking points. It's correlated with the corner segment.

Heres an mph with both long and lat G overlaid. It's correlated with corner segment.
