ive had more time on it and i still feel it helps on a slick track. if any where i notice it the most is it hooks up better out of corners that go onto a straight if thta makes any sense.

on corners that follow one another it can get a little pushy, like in switch backs or "S" turns.

ive also noticed it makes the belt skip alot more. run it when there are no other cars on the track or out in practice and you can hear the belt skip.
