Powerflex Lower Coffin Control Arms with Poly Bushes Front Only – Porsche 987 Gen1 / Gen2 Boxster & Cayman
Imprecise handling? Uneven tyre wear? Braking instability?
These common issues are often caused by worn suspension arms and ageing rubber bushes. The Powerflex Track Control Arm (Coffin Arm) Pair with Bushes is a complete replacement solution designed to restore suspension geometry and improve front-end stability on your Porsche 987.
Supplied as a matched pair of fully assembled coffin arms, this kit includes Powerflex Road Series polyurethane bushes pre-installed, eliminating the need for pressing or reusing tired OEM components. By reducing unwanted suspension flex, it delivers improved front-end control, greater stability under braking, and more consistent tyre contact — all while maintaining excellent road comfort.
