If so, by how much? I'm gonna install one soon and not sure I would bother doing that unless people rave about it and says its a must. Seems like it would look weird at least and maybe feel odd too.
Mine is rotated to a position that is comfortable to me and my driving style. I actually spent a good 20-30 minutes just adjusting the handle to the correct position. Mine is not as extreme as the one pictured but I would take the time to do it.
Mine is angled about like Tim's, but I have the orange handle which I believe is a little longer than the silver one. I would suggest driving it for a day or two without the boot. That way you can easily make small adjustments until you get it where it feels best to you.
When I installed mine, I put the trans in 5th gear, then made the handle as comfortable as possible. That's the furthest you're going to have to reach, so you might as well make it as close to you as possible.
