I put these side by side:
I think it is all tire grip, brakes and LSD, I seem to drive the same?
Rear tires because they were corded day one and full thread day 2, the front hooks up much better but that is because LSD losened up, the front tires I had in 2011 were about 12/13 days old.
2010 Much faster through sweepers, ass planted much more. What I lose in T1 I make more than up through S-es. Temps were colder needed 6th. on back straight, even coming out of Oaktree slower in 2nd.
2011 Much faster through T1 and oaktree.
Next time I will try short shifting through the small first S-es.
