Motorsport Adjustable Control Arm. Porsche 996 GT2 / GT3 / GT3RS  ❭  99634112

Control arms are critical suspension links that locate the wheel assembly relative to the chassis while allowing controlled suspension movement. Their geometry directly influences wheel alignment and therefore affects tyre contact, steering response, stability and handling.
The adjustable design is particularly valuable on competition, track-prepared or modified vehicles where suspension geometry may need to be optimised following changes to ride height, wheel and tyre specifications or other chassis settings. Adjustment can allow a specialist to achieve alignment settings that may not be possible with a standard fixed arm.

What This Product Does:

• Locate and control the wheel assembly relative to the chassis.
• Allow controlled suspension movement while maintaining wheel location.
• Provide additional adjustment for suspension geometry.
• Allow more precise wheel alignment for compatible applications.
• Help optimise tyre contact with the road or track surface.
• Support specialist chassis setup for motorsport and performance use.
• Can assist with correcting geometry following appropriate ride-height changes.
• Help achieve desired handling characteristics when professionally adjusted.
• Provide an upgrade from fixed suspension geometry where additional adjustment is required.
• Replace worn, damaged or unsuitable control arms.

• Knocking, clunking or rattling from the suspension.
• Excessive play in the control arm joints or mounting points.
• Loose or worn spherical joints, bushes or associated components.
• Steering that feels vague or inconsistent.
• Reduced stability during braking or cornering.
• Vehicle pulling or wandering on the road.
• Difficulty maintaining the required wheel alignment.
• Uneven or accelerated tyre wear.
• Changes in handling or steering response.
• Visible bending, cracking or physical damage.
• Corrosion or deterioration affecting the component.
• Adjustment hardware that is damaged or can no longer be securely set.
• Suspension geometry moving out of specification after adjustment.
• Damage discovered following heavy track use or an impact.

• Control arms are structural suspension components that directly influence wheel position and alignment. Excessive wear, damage or movement can allow suspension geometry to change while the vehicle is being driven, negatively affecting steering precision, tyre contact and vehicle stability.
• This becomes especially important in motorsport and high-performance applications. Higher cornering forces, aggressive braking, track kerbs and performance tyres can place substantial loads on suspension components. Any unwanted movement within the control arm or its joints can compromise an otherwise carefully configured chassis setup.
• Incorrect suspension geometry can also cause rapid or uneven tyre wear. On a performance vehicle, relatively small alignment changes may noticeably alter steering response, cornering balance and tyre behaviour.
• Adjustable control arms additionally depend on their adjustment and locking mechanisms remaining secure. Damaged, incorrectly adjusted or inadequately secured hardware can allow the geometry to move away from its intended setting.
