Hi, Pat,

Since the subject of the thread is RAKE, let's talk about it first. To reiterate Tyson's knowlegable comments, there are two noticable performance advantages to 1 or 2 degrees of rake on most 911es:
(1) The steering geometry has better track feel, and
(2) Aerodynamic lift is somewhat reduced due to less air entering under the front of the car, AND penetration is enhanced (better wedge shape).

Now to corner weights: In our "Prep Your 911" seminars, for those still puzzling about weight bias and weight wedge, we try to leave them with this axiom:

"Without physically relocating any items in the car itself, the rear will always weigh the same, the front will always weigh the same, the left side will always weigh the same, and (obviously) the right side will always weigh the same."

From the above you can see that if one wants to reduce weight on the RR, one MUST add some weight to the RF AND to the LR. How do we do that? Easy -- magic!
