So would a "newer" normal M3W perform better than an older without the relocation of the outer tie rod, yes it would. It would also have less bumpsteer or scrubbing as the wheels move up and down in normal driving.
BUT the Empire equipped M3W would just that little bit better all around and a lot better when driven to its limits.
An excellent, detailed explanation Dan. So the "newer" normal M3W has the same geometry suspension as an older M3W with the "comfort kit" and both of these will perform equally better than the terrible bump steering original set up. As you say, the Empire kit sorts out more of the problems and is another but less noticeable, in normal use, improvement. I can confirm that it is better at the limits. I had a couple of experienced and skilled 3 wheeler drivers try my Empire equipped car on a track at the MTWC training day last weekend and they were impressed by its handling compared to the standard car, particularly that it turned well into corners and didn't need mid corner corrections.
