I put one of
these (link) in the Cobra today. I haven't drive it yet, but just from rowing through the gears with it I believe it fixed one of my biggest ergonomics complaints with my car. I can shift into 5th and 6th without having to lean forward off of the seat now.
Overall all of the shifts felt more comfortable, though 2nd and 4th feel a lot different because the shifter is leaned back a good bit. It looks a little funny in 2nd, 4th, and 6th, but it's not ugly or anything. I think I'm going to be very happy with it.
