Suspension Application

These control arms form part of the McLaren 720S rear suspension system. Their function is to help control the movement and position of the rear wheel relative to the chassis.

Correct suspension geometry is particularly important on the 720S because the vehicle is designed around high-performance handling and precise chassis control.

A damaged or incorrectly fitted control arm can affect:

• Wheel alignment
• Handling
• Tyre wear
• Straight-line stability
• Cornering behavior
• Suspension movement

Condition

For a used control arm, carefully inspect:

• Aluminium arm body
• Bushings
• Ball joints
• Mounting points
• Threads
• Joint boots
• Signs of bending
• Cracks
• Corrosion
• Impact damage
• Previous repairs

Used listings for these references can have different conditions, so the actual item should be inspected before installation. (eBay)

Fitment Verification

Because McLaren suspension components can have different part numbers for different positions and configurations, verify the original part number before ordering.

Check:

• Vehicle VIN
• Model year
• 720S Coupe or Spider
• Rear-left position
• Original control-arm number
• Mounting configuration

Do not rely only on the product title when matching a suspension component.

Package Includes

• 1 × McLaren 720S Rear Suspension Control Arm
• OEM reference: 14B0579CP or 14B0581CP

The exact quantity should be confirmed before purchase. Bushings, ball joints, mounting bolts and other suspension components are not included unless specifically stated.

Installation

Professional installation is recommended.

After installing a suspension control arm, the vehicle should receive a complete four-wheel alignment. Correct alignment is important to ensure the rear suspension operates according to factory geometry.

The technician should also inspect the surrounding suspension components for damage or excessive wear.

Important Fitment Notice

14B0581CP is documented as a rear-left upper control arm for the McLaren 720S, while 14B0579CP is also associated with the rear-left control-arm assembly.
