Now, before I get into the actual review, I'd like to note this panhard bar has spherical rod ends. What the difference is from stock is, the stock one is not adjustable, and has rubber bushings. Spherical rod ends are metal. No rubber. Expect increased noise in the cabin, and expect your rear end to clunk on acceleration at low speed. With that being said.. The bad: The road noise increase was pretty substantial. I can hear the whine of the differential, I definitely hear when the suspension loads/unloads. The good: The rear end is a lot more predictable now, I don't have a soft squishy feeling at the limit of traction anymore, and the feedback in the chassis is much improved. Overall, knowing what I know now, I'd STILL opt for the spherical rod ends. The amount of "squish" eliminated from the rear suspension is worth all the extra noise coming from the back.
