I'm not sure about the Steeda STS, but I'd have to guess that it's shorter than stock.
As to the "notchy" feel, no it doesn't change in that respect. When you do this mod the shift feels less sloppy and you have to push/pull a little harder to change gears, but you can shift a little faster as the throw is a little shorter
