Information
Control arm lower, Rear.
This lower control arm (sometimes called “rear lateral arm / suspension arm") is used for the rear suspension of Porsche 987 (Boxster / Cayman) models — covering both Gen1 and Gen2. The part is supplied as a single arm (left or right). For best results and balanced suspension behaviour, replacement of both rear arms (left + right) is recommended when bushings or joints show wear.
Sold each, Fits left and right side.
Fits:
Porsche 987.1 Boxster 2005 - 2008
Porsche 987.2 Boxster 2009 - 2012

• Position: Rear lower control arm / lateral link - connects rear axle assembly to chassis/subframe, controlling wheel lateral and longitudinal position under dynamic loading.
• Functions: Maintains correct wheel alignment geometry under load, ensures stable rear-end handling, helps manage camber and toe changes, absorbs suspension loads, supports consistent tyre contact and handling predictability.

Supersession: Part 90037805109 is superseded by 90037805101
This bolt secures the rear suspension control arm to the wheel carrier or subframe, providing the clamping force needed to maintain accurate suspension alignment and minimize movement under load.
Over years of service, high torque loads, vibration, and exposure to road conditions can weaken or corrode suspension bolts. A compromised bolt may lead to improper alignment, handling instability, or noise under braking and cornering.
When to replaces:
• During control arm replacement, alignment service, or rear suspension rebuilds
• If original bolts show corrosion, stretching, or thread wear
• As part of preventive maintenance when reassembling load-bearing suspension joints
Replacing with Genuine Porsche hardware ensures structural integrity, precise fit, and lasting performance.
