The concave washer sits within the shock absorber mounting assembly and helps evenly distribute clamping force across the suspension components. Its specially formed curved profile supports the correct positioning of the shock absorber mount, helping maintain suspension geometry and reducing stress on mounting surfaces during suspension movement.
Functions & Technical Role
• Load distribution: Spreads suspension forces evenly across mounting points
• Mounting support: Assists correct positioning of the shock absorber assembly
• Suspension stability: Helps maintain proper suspension alignment under load
• Vibration control: Reduces stress and movement within the mounting assembly
• OEM precision: Manufactured to Porsche specifications for exact fitment and durability
Fitment / Position on car
• Fitting position: Front axle suspension
• Location: Shock absorber / strut mounting assembly
• System: Front suspension and damping system
The concave washer supports correct suspension mounting geometry and helps prevent uneven stress on suspension components. Proper load distribution is essential for maintaining ride quality, handling precision, and long-term durability.
When to Replace
• During shock absorber or suspension overhaul
• Damaged, bent, or corroded mounting hardware
• Suspension noise or movement from the strut assembly
• Following accident or suspension impact damage
• When replacing associated suspension mounting components

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

Supersession: Part 90037805109 is superseded by 90037805101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.
