With over 35 years of experience in manufacturing air suspension components, Arnott Suspension Products offer the best quality replacement parts.
Instead of copying OE items, we study the main causes of failure and engineer improvements to make the quality item shown here.

The valve block is a direct replacement for the vehicle's failing OE valve block. An air suspension solenoid valve block distributes air from the compressor to the air springs and air struts. Over time, valve block O-rings can dry rot and leak air causing the compressor to overwork or allow moisture to degrade the electrical solenoids components.

Lateral support clamp anti roll bar. 

powerflex

Anti-Roll Bars (ARB’s) play an important role in a vehicle’s suspension system, helping to reduce body roll by transferring cornering load from one side of a vehicle to the other.

Often mounted to the vehicle’s chassis with rubber bushes, these bushes ensure the bar works as intended. To prevent the anti-roll bar from moving laterally within its mounts when turning, OE manufacturers will either bond the bushes to the bar, add dead-stops to the bar itself, or rely solely on the clamping pressure of the rubber.

But what happens when those bushes wear and need to be replaced? Often anti-roll bars with bonded bushes come as a costly complete assembly, so the alternative is to fit a more cost-effective unbonded polyurethane replacement, like the many we offer.

In most cases, friction from the bush will prevent any side-to-side bar movement. Still, when turning aggressively or cornering at higher speeds, a laterally shifting anti-roll bar decreases the efficiency and effectiveness of the bar, changing the dynamics of your suspension system in unpredictable ways. It also poses the risk of the bar fouling on other areas of the vehicle or suspension system.

About Suspension Upgrades

Porsche Suspension Upgrades & Components

Your Porsche’s suspension is the key to its handling, comfort, and safety. Upgrading or maintaining your suspension system not only restores factory performance but also unlocks sharper cornering, improved ride quality, and greater driver confidence.

At Design911, we supply a complete range of suspension upgrade parts for Porsche, including:

  • Anti-Roll Bars
  • Control Arms
  • Lowering Springs
  • Drop Links
  • Strut Mounts
  • Polyurethane Bushes
  • Engine / Gearbox Mounts

We stock world-renowned performance brands such as DesignTek, Bilstein, Ohlins, Koni, Powerflex, H&R, KW, and Nitron, trusted in both road and motorsport applications

Why Upgrade Your Suspension?

  • Improved Handling – reduce body roll, sharpen steering response, and corner with confidence
  • Better Ride Quality – balance comfort and control for road or track use
  • Increased Durability – high-quality components outlast standard rubber parts
  • Performance Customisation – tailor ride height, stiffness, and response to your driving style
  • Safety & Stability – maintain consistent contact with the road under all conditions

Key Suspension Components

Anti-Roll Bars (Sway Bars)
Reduce body roll during cornering, keeping your Porsche flatter and more stable. Perfect for spirited road driving or track use.

Lowering Springs
Improve handling and aesthetics by lowering your car’s centre of gravity. Can enhance steering precision while giving your Porsche a more aggressive stance.

Drop Links
Connect anti-roll bars to the suspension arms. Upgraded drop links ensure accurate movement transfer and eliminate play that can develop in worn components.

Strut Mounts
Provide the critical connection between the suspension strut and chassis. Replacing tired mounts restores steering accuracy and reduces knocking noises.

Polyurethane Bushes
A performance upgrade over standard rubber bushes. Poly bushes (such as Powerflex) offer increased durability, sharper response, and reduced flex under load.

Engine Mounts
Help stabilise the engine under acceleration, braking, and cornering. Upgraded mounts reduce drivetrain movement, improving handling feel and gear change precision.

Common Signs of Suspension Wear

  • Knocking or creaking noises over bumps
  • Excessive body roll or poor cornering stability
  • Uneven tyre wear
  • Steering feels vague or less responsive
  • Ride height appears uneven
  • Vibration or harshness through the chassis
