98733104304/4

Product 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
Porsche 987C.2 Cayman 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 set is ideal for vehicles showing rear-end instability, knocking noises, or alignment issues caused by aged or worn control arm bushings.

• Part Numbers / Cross-References: 98733104304 (current), 98733104302 / 98733104303 (previous numbers)

• 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.

The rear lower control arms maintain correct camber and toe alignment during suspension travel. They stabilise the rear axle under dynamic load and help ensure consistent tyre contact and grip. As a matched pair, they work together to deliver the balanced handling and responsiveness expected from a Porsche mid-engine chassis.

Benefits of replacing as a pair:
• Restores identical suspension behaviour on both sides
• Ensures consistent camber and toe alignment
• Eliminates uneven tyre wear caused by mismatched bushings
• Improves high-speed stability and cornering predictability
• Ideal for full rear suspension refresh or alignment correction

With time, the bushings and joints inside these arms deteriorate, causing unwanted movement, clunks, instability and poor alignment. Replacing both arms ensures complete restoration of rear suspension accuracy, improving handling sharpness, road feel and overall safety.

When to Replace:
• Knocking or clunking noises from the rear over bumps
• Excessive play in rear suspension arms during inspection
• Uneven or premature rear tyre wear
• Alignment cannot be maintained (camber/toe constantly shifting)
• Rear-end feels unstable during cornering or acceleration
• Performing a full suspension overhaul
