I dunno whether or not I buy into this?

S2Ki Diff Collars link. Replace OEM bushes on diff hangers etc.



Before:





After:




Key Points:
1. Improved drive feeling through torque application with a more direct initial throttle response.
2. Improved up shifts and down shifts: Up shift are direct with an improved application of torque and power. Heel and toe down shifts give the driver an improved feeling of the rev match.
3. Improved feedback when approaching & exceeding the tires traction limits (wheel slip).
4. Wasted motion / deflection through on and off throttle application of the OEM bushing is significantly stiffened.
5. Just enough compliance to eliminate unwanted vibrations during normal street driving.
Thoughts?

I for one, though skeptical, at only $95US I'm thinking of picking up a set for when I have to do my diff anyway.
