A Quick Look at Moshammer

MOSHAMMER information on this page is based on details supplied by the manufacturer or distributor, plus any OE references provided with the parts.

Choosing the Right Fit for Your Porsche

Where Moshammer is listed for Porsche, use the supplied model coverage and OE references to confirm suitability. Check details that commonly affect fitment such as model year, side/position, and connector type where relevant.

  • Owners typically choose Moshammer body styling parts when they want a more aggressive or modern look with quality finishing, to refresh tired exterior panels or personalise their Porsche with parts designed around Porsche fitment.
  • Common issues these parts may address include panels that no longer sit correctly, aged or damaged exterior styling components, or a desire to improve aerodynamic intent on fast-road or track-day cars.
  • Watch for real-world symptoms such as fitment variation, panel alignment issues, paint prep sensitivity, and cracks if composites are installed under stress or without proper support.
  • Practical tips include dry-fitting all components before paint, using the correct fixings, and avoiding over-tightening to reduce the risk of stress cracks or distortion.
  • Before painting or modifying any part, confirm correct fit on your specific Porsche generation and body style, as many kits are model- and facelift-specific.

Browse by Category

If you already know the area you are working on, start with the category and then filter by Porsche model. Where real-world symptoms and typical reasons to replace are provided, use them to keep the wording grounded.

Chassis / Bodywork — Chassis and bodywork components are changed to repair accident damage, resolve corrosion or straighten a shell, and to carry out restorations or modifications while keeping the Porsche structure safe and true. Common issues include rust in sills and arches, distorted chassis rails after impacts, and misaligned panels from old repairs. Moshammer styling parts within this area are typically used where owners want clean integration with factory body lines.

Boots / Rear Lid / Locks and Latches — Rear lids, locks and latches are replaced when the boot or engine lid will not stay securely closed, is hard to open, or has been disturbed during repainting or panel replacement. Symptoms often include worn catches, corroded strikers, stretched or broken cables, misalignment and water leaks around the latch zone. Choosing the right components helps restore smooth operation and consistent panel gaps on your Porsche.

Exterior Styling / Spoilers — Exterior styling and spoiler parts are used to refresh or transform the appearance of a Porsche, sometimes with aerodynamic benefits. Real-world reasons to change include replacing damaged trim or bumpers, updating to a more aggressive or heritage-inspired look, or matching OEM, GT or motorsport themes. Typical issues these parts address are poor panel gaps, cracked mounting points, faded or peeling finishes and rattles or wind noise from ill-fitting pieces.

Rear Spoilers / Aerofoil — Rear spoilers and aerofoils play a key role in aerodynamic balance, helping manage airflow, reduce lift and increase rear stability. They are replaced when original items are cracked, faded, loose at speed or no longer match the desired styling. Common symptoms include movement at speed, delamination or paint wear, rattles and water ingress around mount points, all of which signal the need for repair or upgrade on your Porsche.

Moshammer — Moshammer-branded exterior components are chosen for OEM-plus styling, subtle aerodynamic intent and Porsche-specific fitment. They are often used on period-inspired builds, restorations or lightweight conversions where panel accuracy and clean alignment with factory lines are important. Real-world issues they help address include replacing tired factory panels, achieving a more balanced stance and resolving previous poor-quality body conversions.
