Handling Problem, any ideas?
 

When I make right turns, my right front lifts and feels unsettled with more chassis roll and more bump steer feedback in aggressive corners.

When I make left turns, there is less front roll...the left front doesn't lift as much as the right, and feels more settled, staying flatter (less roll)

Note: the front suspension has less rebound damping than the rear of the car, so it will lift/float after returning from compression, but that seems even left to right.

The front of the car feels slightly unsettled in bumpy corners in general, when compared to the rear which feels rock solid. I know the PO had two new shocks installed in the rear (Bilsteins).

Any ideas?

An alignment should be able to pin point where the problem is. Otherwise, we would just be guessing and
wasting your time.

The alignment is good from the seat and I doubt that's causing what I'm seeing....tracks pin straight on the gas and on the brakes, and the car rolls noticeably when making rights...that would not be affected by alignment, right?

I'm thinking it has to do with something not doing its job... shock with insufficient rebound damping, or torsion bar that's too soft on the left side somewhere (front or rear?) or a bushing allowing something to give excessively to lift.

I'm fairly competent setting cars and race motorcycle suspensions, however this is my first 911 so I'm trying to see if someone has opinions based on previous experience with the 911 handling characteristics and what affects this type of thing.

I'd love to do slaloms with a video to see what the chassis is doing, but just hoping someone recognizes this as a symptom to a particular problem

Check your sway bar mounts. They can and do break and you may have broken one side

Post a pic and show me your ride height.

The very first thing to do is ensure that you have proper suspension travel.

perhaps your body wieght has something to do with it? being that you are on the left side of the car. also, the may just seem to roll more because you are on the left side, which goes down and the right goes up.
its kinda like when i had a sail boat. when i was on the hull that was out of the water, even though it may not have been out that much, it was all perspective, if i moved to the side that was low, it was scary becuase it seemed like the high side was even higher, even though it was still out of the water the same amount.


corner balance the car, maybe even with you in it.

I'm guessing that the torsion bars are maladjusted. One side is carrying the whole load. Jack the car up under the engine and see if the ride height is nearly the same at each front wheel.
