Information
Control arm lower, Rear.
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.
Sold each, Fist left and right side.
Fits:
Porsche 987.1 Boxster 2005 - 2008
Porsche 987.2 Boxster 2009 - 2012
Porsche 987C.1 Cayman 2005 - 2008

• 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.

Information
Rear control arm hexagon head bolt, M 14 X 100.
Designed for the rear axle control arm on Porsche 996 and 997, it provides exact factory fit, strength, and corrosion resistance.
Sold each.
Fits:
Porsche 996 1998 - 2005
Porsche 997.1 2005 - 2008
Porsche 997.2 2009 - 2012
Diagram ref no 18
Thread size / spec: M14 × 1.5 × 100 mm
Supersession: Part 90037805109 is superseded by 90037805101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.
