95 it's engine mass. You need to find chassis mass (over 700 kg).Can you elaborate what you did ? Cause i dont know if im doing something wrong. I exported Ferrari xml, i changed <Mass value="95.000000" /> to 150.000000 imported again, saved, played a grand prix ( 5 laps ) and ferrari stayed 1st and 2nd. So i came back and change it to 200,000000, played another one, and 1 ferrari came in 3rd, the other one 1st, then im playing practice 3 in Carrer and ferrari came in top 5. So nothing changed really.
