I guess tyre compounds have become better over the years too.
I wonder about that the 288 is only 4 sec faster, also that the 348 is faster than the testarossa and also the the 512TR is faster than the 288. seems to me not logical when I think to the weight of the 288
The 360 is noticeably absent from that list. I think it's funny that the 612 is faster than a 575M there.
