Manufactured from high-quality automotive-grade plastic, the spreader rivet is resistant to moisture, corrosion, road salt, oils and temperature fluctuations. The expanding centre pin locks the rivet firmly into place, ensuring reliable retention while helping to minimise vibration and movement of attached components. Precision-moulded to the original Porsche dimensions, it provides direct OE-style fitment for numerous applications throughout the vehicle.  

What This Product Does:
  • Secures body panels, trims and protective covers.
  • Expands when installed to provide a secure fixing.
  • Helps prevent movement and vibration of attached components.
  • Supports correct alignment of trim and body panels.
  • Allows quick installation and straightforward replacement.
  • Resists corrosion unlike conventional metal fasteners.
  • Replaces damaged, worn or missing plastic rivets.
  • Suitable for a variety of Porsche body and trim applications.

Symptoms Of Wear Or Failure:
  • Loose trim or body panels.
  • Rattling noises while driving.
  • Wheel arch liners or undertrays becoming insecure.
  • Missing or broken retaining clips.
  • Panels sitting unevenly or out of alignment.
  • Damaged or brittle plastic fasteners.
  • Components vibrating excessively.
  • Trim becoming detached during driving.
  • Visible deterioration caused by age or UV exposure.
  • Difficulty securing replacement panels correctly.

Why Replacement Matters:
  • Plastic spreader rivets are exposed to continual vibration, moisture, dirt, road salt and changing temperatures. Over time, the plastic material can become brittle, crack or lose its retaining strength, particularly after repeated removal during servicing or repairs.
  • A damaged or missing rivet can allow trim panels, undertrays or liners to move excessively, creating rattles, poor panel alignment and, in some cases, complete detachment while driving. Missing fasteners can also place additional stress on surrounding clips and mounting points, increasing the likelihood of further damage.
  • Replacing worn or damaged fasteners with the OE Match Plastic Spreader Rivet restores the secure attachment of body and trim components while maintaining the original appearance and fitment of your Porsche. Manufactured to OE standards from durable automotive-grade materials, it provides reliable retention, straightforward installation and long-lasting performance across a wide variety of applications.

Wheel Arch Lining, Front.
Restore the inner protection of your front wheel arches with these genuine OEM liners for the Porsche 911 (997) series. The left side part 99750420301 covers the rear section of the front left wheel arch, and the right side part 99750420401 covers the rear section of the front right arch. These moulded plastic liners are designed to fit precisely, shielding suspension and body components from debris, water spray and contamination while improving acoustic and aesthetic finish inside the arch area.

Fits:
  • Porsche 997 MK1 Carrera 4 3.6L 2006-08
  • Porsche 997 MK1 TURBO 2007-09
  • Porsche 997 MK1 GT2 2007-09
  • Porsche 997 MKII Carrera C4 3.6L 2009-12
  • Porsche 997 MKII Turbo 2010-13

What This Product Does:

  • Protection: Shields the inner wheel arch, suspension components, wiring, and bodywork from debris, mud, water spray, stones and grime kicked up by the front wheels.
  • Acoustic and Cleanliness: Helps keep the arch area quieter (reducing wheel-well noise) and cleaner by providing a barrier rather than leaving components exposed.
  • Finish & Fitment: Ensures that the bodywork has correct finishing inside the arch; if the liner is missing or damaged, the arch area looks incomplete, components are exposed and corrosion risk is higher.

Symptoms & Signs You Might Need Replacement:
  • Visible damage or missing liner inside the front wheel arch: e.g., split or cracked plastic, detachment, missing fasteners, or the liner entirely absent.
  • Excessive dirt, debris or corrosion inside the wheel arch or on inner body panels — if the liner is compromised, the arch is less protected.
  • Unusual wheel-arch noise or increased road noise: If the liner is loose or missing, suspension components may be exposed and road spray or debris may enter areas that were previously shielded.
  • Wear from age: These liners may become brittle, cracked or partially detached with age, particularly on cars used in regions with road salt or heavy use.

Why Replacement Matters:
  • Component protection: Replacing a damaged liner protects suspension, brake lines, wiring and body panels from damage and corrosion.
  • Vehicle integrity and value: For premium or collector cars like the 911, original-fit liners help maintain appearance, fitment completeness and resale value.
  • Finish and appearance: Ensures that the wheel arch area looks correct, aligns with bodywork, and the interior of the arch isn’t exposed.
  • Noise/Vibration: Proper liners help reduce ingress of road spray, minimise wheel-well noise and contribute to a refined driving experience.
  • Preventative maintenance: Installing a new liner before serious damage occurs is cheaper than dealing with rust, debris-damage or incorrect suspension component exposure later.
