    I had these installed by Tesla on my 1.5 Roadster and they made a noticeable difference. The rear-end stays tight on sharp curves while the front is unaffected.
    Overall, the ride is much more confident.

    I have the OEM Eibach stock sway bars in case anyone wants them.

    I don't see a link in your post to a page about your new anti-sway bars, or any mention of where you got them from.

    I got them from Tesla service - there is no link. I ordered via phone from the service manager. They happened to have the suspension kit in stock.

    Personally swaybars are used to fine tune your suspension, not to be an integral part of the system. You have to tune the system before dialing in your fine tunes. You sold your Nitrons. Why? What did you move to? You might be able to sell the custom driver's side shock mount if you're not using it here.

    My Nitron 1-ways are perfect for street driving. If I was doing track and wanted more granular adjustment I'd move to a 3-way or more. But no need. Nitrons are still performing as well as the day they were put on.

    Also what roads and speeds are you basing your analysis on?

    If you removed your Nitrons and then put on the swaybars, you have too much variance to judge how the upgrade performed. Best would have to leave the Nitrons on, put the swaybars on, dial them in close to what was on your stock swaybar in terms of holes/distance, then verify.

    I agree that it isn't exactly an apples to apples comparison as I went back to OEM sport shocks. Those are adjustable. The Nitrons are a great set of shocks, razor sharp handling and stiffness that is just right for the car.
    The rear end sway is amplified too much with the Nitrons - maybe it is specific to my vehicle.
    My analysis is the local roads I drive daily which is where I spend 99% of my time in the car.

    How is the rear end sway amplified by the Nitrons?

    I've seen nothing but the Nitrons taking out the slop from the stock non-adjustable Bilsteins that are a death trap and destruction to a Roadster waiting to happen. Toyota Camrys with the stock toyota shock configurations handle better than that. The non-adjustable Bilsteins didn't give the car a roll or slop either, their issue was that they didn't dampen the rebound fast enough, it was too quick allowing the spring to expand to fast. Too quick and too fast of a rebound takes the weight off the rear wheels when you need it most, and that in itself is a HUGE problem and a car I don't want to drive at all. Its an accident that easily could have been avoided with proper testing and driving knowledge paired with the right shock. You'll tail spin in an instant rebounding that fast and you can't chance that in a rear weighted favored car.

    You know you could have just went to a higher spring rate in the rear if the issue was that you felt it was too loose in the back. I've honestly never felt any slop or sway back there running the Nitrons on my 1.5 at all pushing it to its breaking point and drifting and I have the stock non-adjustable swaybars. I drive Highway 17 each weekday and push the car very hard each time in terms of handling, acceleration, and braking. Again, I've not see an issue. Also the Nitron's also allowed you to lower the ride height, that also would reduce any sway or slop, so that was another option you could have tried.

    If you went to the Bilstein adjustable be aware they fail early, seals, in some cases and not good with backing up their warranties. I'd never put a damn Bilstein on any of my cars or trucks. You're just paying for the name. There's many other shocks that surpass them on the market for the money they charge for a shock. You also don't need 7-way adjustment on the street anyways. Its for again fine tuning things once you've got the basic parts and understanding of your car's handling down where the benefits are mostly seen on the track. Some of the best shocks are only 3-way adjustable.

    I personally feel that when you start adding more adjustments like 7-way on your shock you start to run in all types of issues unless you know what your doing. Too much variance, variables, and your average driver does not know what the heck all of those adjustments mean nor do they know how to dial them in. I'm a firm believer in keeping things simple until you understand what's going on with all the components, adjustments, how/what they mean, and how each adjustment affects the handling of the car.

    If there was any shock that I was going to replace my 1-way Nitrons with it would be with the Motion 3-ways:

    The shocks I got are not the Bilsteins. These are the 1-way adjustable coil overs that are in the upgraded 2.5 sport. Not sure who makes them. They are slightly less stiffer than than the Nitrons.
    The Nitrons were 550/700 lbs and these are 450/600.

    Forgot the aluminum plates at the bottom block everything out. You can't see the sway bars.
