Powerflex Adjustable Track Lower Control Arms (987 Cayman / Boxster)


Designed to fit:

  • 2005 - 2012 Porsche Cayman & Boxster (all 987)

(Front or Rear Position)

Product Details

Note - This kit allows for +/- 0.4° adjustment in caster angle, and +/- 0.75° of camber adjustment.

This fully custom-built control arm from Powerflex applies the same geometry as the OEM GT3 control arms with included Poly-urethane bushings to create a budget friendly OEM+ feel, with plenty of adjustment to dial-in your suspension settings.

Stock rubber control arm bushings give a disconnected and mushy feel to the front suspension, especially when worn, as the bushing deflects more than it should. You get sloppy steering, vibrations, and poor handling which makes the car feel unstable. These urethane bushings are stiffer than stock rubber and will not deflect as much. This helps keep the alignment in check with less variation. The car feels more planted and confidence-inspiring. And a lifetime warranty means you'll likely never have to pay for another bushing ever again!

Unlike other urethane bushings using only one or two urethane grades, Powerflex design engineers choose the correct hardness to allow for the specific movement or rigidity required for each component while minimizing unwanted NVH (Noise, Vibration, and Harshness).

Supplied bushing insert:

  • Black (90-95A, approximately 80% stiffer than stock). = Race
