It drives a little worse, i wouldn't recommend taking corners like a vett would and just over all just be more careful when conering. I took mine off this last trip to the strip and picked up .1 on my 60 foots and about the same for my ET. I ran below on my sig with taking it off.
I've "heard" that with a larger rear sway bar (ATR for example) and no front sway bar, they drive the same as having a stock front and rear. ???? Going to find out how bad it drives next time at the strip, best 60' I can get has been 1.74.
