Actually, I was curious about the weights, so I looked on this website which shows lots of interesting car (and track) data:

http://www.track-challenge.com/main_e.asp

If you click on comparison in the left margin, then select GT3 (old) and Modena 360, it shows that the Modena is heavier than the GT3 (and slower around Nurburgring and Hockenheim). The weight for the 360 is over 3200 lbs, so if the Stradale is 100kg less, it would still be close to 3,000 lbs (wet). Are these numbers wrong?

Thanks,
