My box is a firm feel stage 2 or 3. Not sure because it was in the car when I bought it. Im sure the sector shaft bearing is doing its job. I think a fix would be to install the long pitman arm (which I have on a shelf) and idler arm, but I can't because I have TTi exhaust that barely clears the idler arm now. I had to compromise something during my build and this was it. I chose the exhaust, and now I have to deal with mopar steering instead of BMW steering. Maybe then ratio is what throws it off and makes it feel less precise than I would like it. I actually like my box otherwise.
daveh, I think the sector shaft support is worth the investment if you are looking at making your car perform better. The steering box mount is notorious for being flexible, especially if you are running large tires and putting huge cornering/steering forces into it. Anything to help that will only translate to better steering. If you just have a low hp cruiser with skinny tires and have no possibility of seeing a curvy road much less an autocross track, it probably won't matter. These cars are expensive, and I figured the $$ was worth the possible advantages of creating a better steering and suspended car.
