In my -9A, it has no effect on foot position nor does it decrease leg room. My plane is fuel injected, but the fuel pump is under the cowl on the firewall, so nothing in the tunnel. I didn't understand that stuff when I bought it, but I do have the angled bar instead of the straight one, even though I could have just as well used the straight one. I happened to mention that to Alan one day and he volunteered to swap it out, but I kind of like that angle. No issues. It doesn't eliminate stepping on the seat but it makes it much easier to get in and out. It's an excellent addition. It does provide a place to put your feet while flying, and it does eliminate the need to use the landing gear weldment in order to push yourself out of the airplane to exit, thus saving the carpeting that goes over that weldment. It's a very, very cost-effective airplane accessory.
