As a critical fastening component, the wheel mounting bolt secures the wheel and brake assembly to the hub, ensuring safe vehicle operation under all driving conditions. Over time, wheel bolts can suffer from corrosion, thread damage, stretching through incorrect tightening procedures, or rounded heads caused by improper tools. Replacing damaged or worn bolts with Genuine Porsche components restores factory-correct fitment, safety, and reliability, making this bolt ideal for routine maintenance, repairs, and concours-standard restoration projects.
What This Product Does:
- Secures the wheel safely to the hub assembly.
- Provides the correct 40mm thread engagement where specified.
- Delivers the correct clamping force between the wheel and hub.
- Supports vehicles requiring longer wheel mounting bolts.
- Replaces worn, damaged, or corroded original fasteners.
- Ensures safe wheel retention under all driving conditions.
- Provides genuine Porsche fit, strength, and durability.
Symptoms Of Wear Or Failure:
- Corroded or heavily rusted wheel bolts.
- Damaged or stripped threads.
- Rounded or worn bolt heads.
- Difficulty achieving the correct tightening torque.
- Stretched or overtightened wheel bolts.
- Incorrect bolt length fitted during previous repairs.
- Signs of damage after repeated wheel removal.
- Age-related deterioration of the original fasteners.
Why Replacement Matters:
- The wheel mounting bolts are critical safety components responsible for securing the wheel to the hub with the correct clamping force. A damaged, corroded, or incorrectly sized bolt can compromise wheel retention, resulting in uneven clamping, vibration, damaged threads, or, in severe cases, wheel fastening failure.
- Replacing worn or incorrect wheel mounting bolts restores safe wheel attachment and ensures the correct factory-specified fit and performance. Manufactured to Porsche's original equipment specification and supplied under part number 35633190300, this Genuine Porsche 40mm long brake wheel mounting bolt delivers the precise fit, exceptional strength, and long-lasting reliability expected from genuine factory components.

Whenever brake calipers are removed for servicing, pad replacement, disc replacement or caliper refurbishment, it is good practice to inspect the mounting bolts for wear, corrosion or thread damage. Replacing worn or damaged fasteners helps maintain correct clamping force and supports safe, reliable brake operation.
Manufactured from high-grade steel with the correct dimensions and thread specification, this mounting bolt provides a secure and dependable fit for a wide range of modern Porsche models.
What Does the Brake Caliper Mounting Bolt Do?
The brake caliper mounting bolt fastens the brake caliper securely to the hub carrier or suspension upright. It is responsible for maintaining the precise alignment of the caliper while resisting the significant braking forces generated under heavy deceleration.
Why Replace the Brake Caliper Mounting Bolt?
Brake mounting bolts experience repeated heat cycles,
vibration and extremely high clamping loads. Over time they may suffer from:
- Corroded or damaged threads
- Wear from repeated removal and installation
- Loss of protective coating
- Incorrect torque from previous servicing
- Stretch or fatigue after extended use
Replacing the bolt during brake maintenance helps ensure the caliper remains securely mounted.
Common Symptoms of a Worn or Damaged Mounting Bolt
- Damaged or stripped threads
- Corrosion on the bolt shank or head
- Difficulty achieving correct torque
- Caliper movement due to incorrect fastening
- Fastener showing signs of previous over-tightening
Features
- Direct replacement brake caliper mounting bolt
- High-strength steel construction
- Precision manufactured for accurate fitment
- Designed for demanding braking loads
- Ideal during brake disc, pad or caliper replacement
- Helps maintain correct brake caliper alignment
- Suitable for road and performance applications
