im not even gunna get in this argument about whos car is faster n all this shit, but the only way you chirped the tires going from 2nd to 3rd at 125 is if your car actually goes 125 in 2nd
(which i highly doubt since you said u have a 6 speed which makes all ur gears way lower, so 1st gear with a 6 speed tranny would be lower, making you go slower, than in 1st gear with a 5 speed tranny)
and then you dropped the clutch, revved your engine all the way up to 8500 and popped the clutch. This is what skierman was talking about when he said ur ruining your clutch, which you are no matter if its a fuckin vtec or a fuckin mini van, but sports cars like ur s2000 are made to be driven like a sports car ie high rpm shifting, so ur tranny is fine.
