The OE Match front control arm set includes one left (99634306904) and one right (99634307004) front/rear control arm, providing a complete suspension refresh for Porsche 996 and 986 Boxster models. Together, these arms restore balanced geometry, precise steering response and stable front(rear)-end handling.
Fits:
Porsche 986 Boxster 1997-04 (Front and Rear)
Porsche 996 C2 1998-05 (Front only)
Diagram ref no 5
Perfect for eliminating front-end (or rear-end) clunks, correcting wandering steering, or resolving alignment issues caused by aged bushings or worn ball joints, this OE-Match set offers outstanding performance and value.
Benefits of replacing as a pair:
• Ensures equal bushing compliance on both sides
• Restores symmetrical steering feel and chassis response
• Improves straight-line stability and turn-in precision
• Eliminates uneven tyre wear caused by mismatched suspension parts.
As the original control arm bushings age, they soften, crack or shift under load. This leads to vague steering, instability over bumps and difficulty maintaining alignment. Replacing both arms ensures the suspension operates as intended, improving safety, ride quality and cornering confidence.
When to replace:
• Knocking or clunking noise from the front end (rear end)
• Steering feels loose or unstable
• Uneven tyre wear or alignment that won’t hold
• Excessive play detected in ball joints
• Visible bushing deterioration or cracking.

The 99634306904 (left) or 99634307004 (right) front/rear control arms are high-quality replacements designed for Porsche 996 Carrera and 986 Boxster models. These arms controlling wheel position, maintaining proper camber/toe geometry, and ensuring stable, precise steering feedback. Manufactured to OE specifications.
Fits:
Porsche 986 Boxster 1997-04 (Front and Rear)
Porsche 996 C2 1998-05 (Front only)
Diagram ref no 5
These OE Match arms are ideal for replacing worn or cracked bushings, knocking ball joints, or excessive suspension play that develops with age and mileage.
These arms keep the front wheels correctly aligned by controlling camber and toe changes during suspension travel. Their bushings absorb vibration and maintain chassis stability, while the ball joint allows smooth steering articulation. Together, they ensure the sharp steering response and balanced handling expected from Porsche sports cars.
Over time, the rubber bushings and ball joints deteriorate under heat, stress and road impacts. This leads to vague steering, clunks over bumps, uneven tyre wear and difficulty maintaining alignment. Replacing the arms restores precise suspension control, improves safety and brings back the responsive handling characteristic of Porsche’s front-engine layout.
When to Replace:
• Audible knocking or clunking over bumps
• Excessive play detected in ball joints
• Uneven or rapid front tyre wear
• Steering feels loose or wanders at speed
• Alignment cannot be held after adjustment
• Visible cracking or movement in the arm’s bushings.

Porsche Rear Anti-Roll Bar Drop Links & Bushes | Design911 Suspension Components for Stability & Precision Handling
Rear anti-roll bar drop links and bushes are key suspension components that connect your Porsche’s rear anti-roll bar to the suspension arms and chassis. They help control body roll, maintain balance, and improve grip during cornering and acceleration. Working together, these parts ensure that your Porsche remains stable and responsive, whether on the road, track, or during spirited driving.
At Design911, we stock a full range of rear anti-roll bar drop links and bushes, designed for strength, flexibility, and precision fitment. Each component is crafted from high-quality steel, alloy, rubber, or polyurethane materials to provide optimal performance and long-term durability. Perfect for routine maintenance, restorations, or performance upgrades, our components restore control, comfort, and the legendary Porsche handling feel.
What Do Rear Anti-Roll Bar Drop Links & Bushes Do?
Rear drop links and bushes work as connection points that allow the anti-roll bar to stabilise your Porsche during cornering.
Core Functions:
• Connect the rear anti-roll bar to the suspension arms and chassis.
• Reduce body roll and improve rear-end stability.
• Enhance traction and balance under load or acceleration.
• Ensure smooth and predictable handling in all conditions.
• Minimise vibration, noise, and chassis movement.
Together, these components keep your Porsche composed and confident, delivering optimal cornering precision and road feedback.
Why Do Rear Anti-Roll Bar Drop Links & Bushes Fail or Degrade?
Because they operate under constant motion and stress, these components naturally wear out over time.
Common Causes of Failure Include:
• Cracked or perished rubber bushes causing excessive movement.
• Corrosion or fatigue in metal link rods.
• Loose or damaged mounting bolts or bushings.
• Exposure to heat, moisture, and debris accelerating deterioration.
• Polyurethane bushes losing elasticity after prolonged use.
When rear anti-roll bar links or bushes fail, handling may feel unstable or noisy, with increased body roll, uneven traction, or vibration through the chassis.
Why Replace or Upgrade Your Porsche Rear Anti-Roll Bar Drop Links & Bushes?
Replacing worn rear anti-roll bar links and bushes restores suspension geometry and overall chassis stability. Performance upgrades offer sharper handling, reduced roll, and improved responsiveness.
