And again, there's more to it than just the numbers. With the B or FMJ spindles the bump steer is slightly worse, but the camber gain is better, and as the article explains if you're running a wide, softer tire the improvement in camber gain will be more important. They also have a better SAI. It's all about trade offs, suspension design is ALWAYS a compromise and there's a lot more to it than just the bump steer numbers. I run FMJ spindles on my Duster, there was no noticeable difference in bump steer compared to the 73+ A-body pieces. But I also run 275/35/18's up front and my car is substantially lowered.
I have yet to see a rack conversion for the factory rear steer suspension that didn't have atrocious geometry. I'm not saying it can't be done, but there's a reason why all of the rack conversions are part of a full coil-over conversion. I just don't see the improvements from the design of the rack itself being able to overcome the problems that come up mounting it with this application. Even if you're successful, you'll have done a ton of work for what will likely be a very small improvement in bump steer.
