• Position on Vehicle: Rear axle, control arm position linking rear wheel carrier / suspension to chassis, controlling camber, toe and lateral track stability.
• Cross-Reference / Alternative Numbers: OE ref part 981 331 053 02; also referenced 99733105301 / 99733105302 / 99733105303 / 98133105300 / 98133105301.
Built to meet factory specification and supplied with a premium ball joint, it restores accurate alignment, improves handling precision and ensures long-term durability.
The rear control arm is a critical component in maintaining rear axle geometry, wheel alignment, and dynamic stability under acceleration, cornering or load. A worn, bent or loose control arm can lead to:
• Rear instability or wandering at speed
• Uneven or rapid tyre wear on the rear axle
• Clunking or knocking noises from the rear suspension
• Loss of alignment control (camber/toe drift).
Replacing the arm ensures the rear suspension operates as intended, restoring precision and safety.
When and why to replace:
• You hear a pronounced knock or clunk from the rear suspension when hitting bumps or changing direction.
• Rear tyres wear unevenly or you cannot hold rear alignment specification.

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.

Upgrade your stock or adjustable rear swaybar with this simple bolt in replacement for the factory drop links.
Left & right-hand threaded rod ends allow for simple length adjustment to eliminate swaybar pre-load.
Correctly sized, precision, Teflon-lined rod-ends for smooth and quiet operation, long life, and high reliability. No wear and rattling problems, like those seen with other designs, due to undersized or low quality rod ends.
Eliminates the factory compliant plastic drop link bushings that deflect under loading and quickly wear out.
High misalignment, stainless steel spacers allow for superior bind free operation and corrosion resistance.
Precisely connects the stock or adjustable swaybar to the rear strut assembly for improved feedback and swaybar response.

This high-precision adjustment bolt is engineered to the specifications of the original Porsche part (supersedes 99633121702). It's designed to facilitate the correct camber and toe adjustment of the rear lower control arm on Porsche models including the 996, 997, Boxster and Cayman. Its calibrated threads and dimensions ensure accurate alignment and ensure durable and precise suspension correction.
• Fitment: Rear lower control arm mount—adjustment point for alignment, especially after bushing replacement or arm removal
Rear suspension alignment is vital for handling precision, tire wear and safety. Over time, original adjustment bolts may become stretched, corroded, or damaged from repeated removal and alignment work. A compromised bolt can make accurate alignment difficult, lead to uneven tire wear, and affect vehicle dynamics.
Replacing with a new bolt restores the correct adjustment range and clamping force - ensuring your Porsche’s rear end remains properly aligned and fully controllable. When to replace:
• After performing rear suspension removal, control arm or bushing replacement
• If the existing bolt shows signs of corrosion, thread damage or deformation
• When tires exhibit uneven wear or vehicle exhibits unusual handling at the rear

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.
