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

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.

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Supersession: Part 90037805109 is superseded by 90037805101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.

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.

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.
