I dunno about whether I would get warping on a floating or not but I can assure you that it's nothing to do with riding style.

I used the original 03 rotor when I upgraded the front end....I'm on the 3rd one on the 06 after 6300 miles....

Gina 03 America - Pretty stock - except the TBS wheel... 06 America - missing, presumed in bits. With it's TBS wheel... 09 America - It's very blue....
