This is essentially the same design as the Alta SS, with the addition of a collar that is adjustable by hand to change the length of the shift throw (vs. three small allen bolts on the Alta). I can tell you that from my experience with the Alta SS (installed by Randy at Webb Motorsports) that it greatly improves the feel and shift action of the stock shifter. Once you do it, driving a Mini with a stock shifter kinda sucks in comparison.
BTW Ken I don’t think the piece can be designed to offer a even shorter throw because of clearance issues with the exhaust heat shield…
Y’all should also probably know that installation is no joke, and made significantly easier with an overhead lift — therefore I would recommend for any but the most competent home mechanic that you have a professional like Randy do the install.
