Alignment eccentric washer, also referred to as a cam adjust arm or control arm adjust cam, is used in the rear suspension of certain Porsche 911, Boxster, Cayman and Panamera models.

Position on Vehicle: Rear suspension — at the rear control arm or track rod mounting point, typically used to adjust alignment of the wheel carrier, track bar or control arm.

Applications: Ideal for when original eccentric bolts or washers are worn, alignment cannot be set correctly, or when replacing control arms/track rods and correct alignment geometry is required.

Diagram ref no 4

Bolts securing suspension cross-members endure constant dynamic stress, heat, and exposure to moisture. Over time, this can lead to corrosion, stretching, or loss of clamp force, potentially compromising alignment and safety.

When to Replace:
• During rear subframe or cross-member removal/reinstallation
 If original bolts show corrosion, thread damage, or deformation
 When performing a complete suspension overhaul or alignment service

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.

Rear control arm hexagon head bolt, M 14 X 100.
Designed for the rear axle control arm on Porsche 996 and 997, it provides exact factory fit, strength, and corrosion resistance.
Sold each.

Fits:
Porsche 996 1998 - 2005 
Porsche 997.1 2005 - 2008 
Porsche 997.2 2009 - 2012

Diagram ref no 18

Thread size / spec: M14 × 1.5 × 100 mm
 Supersession: Part 90037805109 is superseded by 90037805101

This bolt secures the rear suspension control arm to the wheel carrier or subframe, providing the clamping force needed to maintain accurate suspension alignment and minimize movement under load.

Over years of service, high torque loads, vibration, and exposure to road conditions can weaken or corrode suspension bolts. A compromised bolt may lead to improper alignment, handling instability, or noise under braking and cornering.

When to replaces:
During control arm replacement, alignment service, or rear suspension rebuilds
 If original bolts show corrosion, stretching, or thread wear
 As part of preventive maintenance when reassembling load-bearing suspension joints

Replacing with Genuine Porsche hardware ensures structural integrity, precise fit, and lasting performance.

Sold each.

Thread size / spec: M14 × 1.5 × 100 mm
Supersession: 90037805109, 90037805101

Since the control-arm mounting bolt bears major structural loads and undergoes vibration and torque stress, it can become worn, stretched, corroded or fatigued over time. This reduces its ability to maintain correct alignment and clamping force - potentially resulting in handling issues or component wear. Replacement is especially important when performing rear suspension service, control arm replacement, or alignment work. Installing the correct bolt restores reliable mounting integrity and ensures the rear axle geometry remains stable under load.

About Suspension & Axle

Porsche Suspension & Axle Parts

Porsche suspension systems are engineered with precision to deliver sharp handling, ride comfort, and maximum performance. Whether on the road or track, your Porsche relies on a finely tuned suspension and axle setup to keep you in control. When components wear out, the ride becomes rough, handling suffers, and safety can be compromised.

At Design911, we supply a full range of suspension and axle parts for classic and modern Porsche models — from shock absorbers and coil springs to control arms and ball joints - helping you maintain your car’s legendary driving dynamics.

 Signs of Worn Shocks or Struts

Shock absorbers and struts are essential for keeping your Porsche stable over bumps and through corners. Some signs they may need replacement include:

  • Excessive Bouncing – car continues to bounce after hitting bumps
  • Poor Cornering Stability – leaning hard into corners, reduced grip
  • Fluid Leaks – damp or oily patches on shocks/struts
  • Uneven Tyre Wear – poor damping leads to increased tyre wear

If left unchecked, worn shocks or struts not only reduce ride comfort but can also compromise safety.

 Common Porsche Suspension Issues

Different Porsche models can face specific suspension-related faults. The most frequent include:

  • Lower Track Control Arm Bushings - Failure causes squeaking noises, uneven tyre wear, and eventually knocking sounds over rough roads.
  • Broken Coil Springs - Seen in models such as the Porsche Boxster. Symptoms include groaning noises when steering and clicking or knocking over bumpy surfaces.
  • Leaking or Worn Shock Absorbers - Identified by damp, oily residue on the shock body. This is one of the most common suspension failures over time.
  • Ball Joint Wear - Worn joints reduce steering precision and can lead to loss of control if ignored.

Fortunately, most of these issues can be resolved by simply replacing the affected parts with OEM or high-quality aftermarket components.

Why Maintain Suspension & Axle Components?

  • Performance – ensure your Porsche handles as designed, with precise cornering and stability
  • Comfort – smoother ride by absorbing bumps and vibrations
  • Safety – worn suspension can increase braking distances and reduce steering control
  • Longevity – prevent excessive tyre wear and protect other connected systems

Why Choose Design911?

  • Extensive Range – shocks, springs, control arms, joints, and full kits
  • OEM & Performance Options – genuine Porsche parts and trusted aftermarket upgrades
  • Classic & Modern Coverage – from early 911s to the latest models
  • Expert Advice – guidance on identifying faults and choosing the right replacements
  • Worldwide Delivery – carefully packed and shipped securely to your door
