For many 981 Boxster and Cayman owners with PASM suspension, a popular upgrade is going from the stock hollow rear sway bar, to the solid rear sway bar as found on the X73 suspension package.

What if you already have a Boxster or Cayman with ohterwise heavily modded suspension? GT3 control arms and sway bar in the front, aftermarket suspension on all four corners? Even the X73 sway bar might be too soft to keep up with the rest of your car.

This is where our new adjustable rear sway bar enters the picture.

Want to have your rear sway bar about as soft as stock? No problem. Want it harder than stock for when you're attacking the twisties? It's got you covered. Now you have the ability to set your rear sway bar to where you want it, to match your driving style and needs.

The rear adjustable sway bar comes with new bushings (the bar itself is a larger diameter than stock), as well as clamping shaft collars to prevent lateral movement (the welded rings on the stock bars have been known to break during hard cornering).

Installation is the same as the X73 installation (4 bolts, 2 nuts), and can be used with your stock drop links, or with adjustable drop links.

  1. BEYOND AWESOME! Review by Michael A.

    What a great tuning tool! I ended up 2nd hole from the back, and the increase is turn in speed is magical. As I was not on track I could not confirm if that is too much rear sway bar for high speed sweepers, etc. For low speed street stuff that setting is killer. The steering effort increased considerable which makes sense to me as now the car is rotating into the turn as opposed to rolling the body of the car. The only part I did not like was the bolt on collars. It made it a pain to make sure the bar was centered. I would prefer a welded on collar.

    I do not think I could push anymore rear sway bar against the stock X73 front sway bar I am currently running. I will have to wait till I get the GT3 front bar installed. (Posted on 3/11/16)
