Yes they are. Three versions of front and rear bars. Non GT, GT and GTPE.
Interesting. Given the springs are the same for the GT and GTPE I would have assumed their sways would be the same as well.
Maybe the appropriate comparison should be the GTPE with the Model Y they tested? I didn't see the detail on which Model Y that was tested...did it have Performance options? The ER AWD rides much better than the Model Y, per many reviewers, so there is always that trade off.
Yours is the first post I have seen that developed a bounce after time has passed. I have seen many who have said the bounce gets better over time. This is a very strange problem. I wonder if you had the bounce before but were not looking for it so didn't notice it? Regardless, if it bothers you, the GT springs should take care of it. Would love to see more data points from people who have done what @markboris did.
I've driven (tested) 3 different MME AWD and one of them where bouncy and uncomfortable. That was a new car with only 15 miles (25km) on the road. I drove 220km as a test drive over a week end it was no good. So - I ordered a MME GT hoping that the Magneride damping system will make the drive more smooth.See! This is what I truly want and need from my First Edition! I don't understand what could be going wrong. Sure, roads in Chicago aren't amazing, but, surely, it can't just be the road quality making this happen. My 2017 Explorer was incredibly smooth and, yes, I know this is a sportier and very heavy vehicle, but seeing people like you noting that your experience with the MME has not been bouncy has me wondering what the heck is going on. I literally feel like I am driving in a see-saw and my wife commented that she had a bunch of neck discomfort when we got home from a 10-mile drive this evening from the south side of the city to the north side. I so want this car to be a success with my family and overall, but I can't have us constantly car sick either and I need to figure out what can be done about it.
It is a fairly easy install but also should be very inexpensive for a shop to do. Looking forward to your report back.
A car’s tendency to be tail-happy (loose or over-steer) is generally caused by excessive stiffness in the rear suspension in comparison to the front. Putting stiffer rear springs into the mix will exacerbate the issue because the rear suspension is getting stiffer in comparison to the front. In order to combat that, the front springs and/or anti-sway bar need to be stiffened up.
I agree with you however when I changed out just the rear springs and nothing else it greatly reduced the bounce (which is only in the rear). Replacing the front springs and struts didn’t do anything for the bounce. Replacing the rear shocks helped a bit more. Overall the handling of the car is much much better. I don’t think you will find anyone with a GT is complaining of a bouncy ride.
