The rear lower control arm is used to replace the original rear lower arm on Porsche 987 Boxster and 987-series Cayman models. It matches the OEM specifications (mounting points, geometry, material strength) to ensure accurate rear-axle alignment, correct wheel geometry and stable suspension behaviour under all driving conditions.

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.
Over time, the rubber bushings and ball-joint interfaces of control arms degrade due to stress, heat and fatigue. This can result in excessive play, clunks over bumps, vague handling, uneven tyre wear, and difficulty maintaining alignment. Fitting a new, correctly spec’d OE Match arm restores precise suspension geometry, improves handling confidence, reduces unwanted movement, and prolongs the life of tyres and associated suspension components.

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.
