I think the main difference with the PHI other than the improvements maintenance wise, is the adjustability. The way the roll center blocks mount to the carriers which then mount to the chassis will allow you to adjust the roll center to pretty much where ever you want by adding shims under the carriers as well as adjust anti-squat in finer degrees. The final drive is also adjustable from I think almost a 2.5 all the way to a 1.7:1. The wheelbase is adjustable between 256, 260 or 264mm while still maintaning the fine tune wheelbase adjustments with the spacers on the arms. All in all, these changes aren't mindblowing but they will allow you to fine tune the new RDX to your driving style alot better. And all this while being easier maintenance wise. What is mindblowing are the new diffs...check them out...no diff screw anymore. If you look through the manual that is posted on the Euro site you can see how all the new adjustments work and also see how the cool new diffs go together.
