Product Information
The OE Match Motorsport Control Arms, Set of 2 are high-performance suspension components engineered to deliver improved handling precision, steering response and chassis control for performance-oriented Porsche applications. Designed to motorsport standards and manufactured from high-strength materials, these control arms provide enhanced rigidity and durability compared to conventional suspension arms while maintaining precise wheel alignment under demanding driving conditions.
NOTE: If upgrading to these control arms from standard arms on a non-GT2 or GT3 model, you will need to purchase the necessary washers and nuts to connect the arm to the flange. Two of each are required per arm. You’ll be prompted to add these to your basket during checkout.
Fits:
Supplied as a matched pair, the control arms form a critical part of the vehicle's suspension geometry, connecting the wheel hub assembly to the chassis and controlling wheel movement throughout the suspension travel range. Their motorsport-inspired design helps optimise suspension performance during fast road driving, track use and performance driving environments.

Supplied as a matched pair, the control arms form a critical part of the vehicle's suspension geometry, connecting the wheel hub assembly to the chassis and controlling wheel movement throughout the suspension travel range. Their motorsport-inspired design helps optimise suspension performance during fast road driving, track use and performance driving environments.
What This Product Does:
- Connects the wheel hub assembly to the vehicle chassis.
- Controls wheel movement throughout suspension travel.
- Maintains accurate suspension geometry and wheel alignment.
- Improves steering precision and driver feedback.
- Enhances vehicle stability during cornering and braking.
- Reduces unwanted suspension flex under load.
- Supports consistent tyre contact with the road surface.
- Improves overall handling performance and vehicle control.
Symptoms Of Wear Or Failure:
- Excessive play in the suspension system.
- Clunking or knocking noises over bumps.
- Vague or imprecise steering response.
- Uneven or accelerated tyre wear.
- Vehicle pulling to one side.
- Instability during braking or cornering.
- Poor wheel alignment that cannot be maintained.
- Excessive vibration through the steering wheel.
- Visible damage, corrosion or bending of the control arm.
- Deteriorated or worn bushings and joints.
Why Replacement Matters:
- Control arms are subjected to continual suspension loads, impacts, cornering forces and road vibrations. Over time, wear of the arm itself, associated bushings or ball joints can compromise suspension geometry and vehicle handling characteristics.
- A worn or damaged control arm can negatively affect steering accuracy, tyre wear and overall vehicle stability. If left unresolved, excessive suspension movement can accelerate wear of other suspension components and significantly reduce driving confidence and safety.
- Replacing worn control arms with OE Match Motorsport Control Arms restores precise suspension geometry, improves steering feel and enhances chassis performance. Manufactured to high standards and designed for demanding driving conditions, these performance control arms provide increased durability, sharper handling characteristics and reliable long-term operation, making them an ideal upgrade for Porsche enthusiasts seeking improved suspension performance.
