Control arm lower, Rear.
This OE Match suspension set includes two rear lower control arms (2 × 98733104304), providing a complete left-and-right replacement for the rear axle of Porsche 987 Boxster and 987 Cayman models. These arms are engineered to replicate the geometry, strength, and bushing characteristics of the original Porsche components, ensuring precise wheel alignment, stable handling, and predictable chassis behaviour.
SET OF 2 - for 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 

Diagram ref no 8

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

本产品取代了保时捷的旧零件编号：
99633104506, 99633104508, 99633104510, 99633104512, 99733104504, 99633104512

该产品的功能：
•提供底盘和轮毂之间的安全连接
•保持车轮定位，确保安全、可预测的操控
•吸收悬架力，同时保持转向精确

随着时间的推移，控制臂可能会弯曲、磨损，或使衬套和球头产生过度游隙。这会导致轮胎磨损不均匀、敲击噪音、车轮定位问题以及转向精度明显下降。更换控制臂可以恢复您的保时捷设计时所需的正确车轮定位和悬架稳定性。
