Klassiek
Klassiek for Porsche
Klassiek parts for Porsche models from Design911.
A Quick Look at Klassiek
Klassiek is chosen for classic Porsche restoration and sympathetic upgrades where owners want correct-style parts that suit older interiors and exteriors. The 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 Klassiek 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 or position, and connector or fixing type where relevant.
- Typical reasons to choose these parts include refreshing worn trim, improving fit and finish, and keeping a classic Porsche feeling original while replacing age-related components.
- Common real-world issues include worn or peeling surfaces, cracked plastics, sagging or misshapen trim, tired seal rubbers causing leaks, and rattles from loose panels, sometimes made worse by previous repairs or mixing parts across model years.
- Before final installation, do a dry-fit, confirm model year and interior or body options, and replace small clips or pads that control movement and rattles.
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 parts are replaced to repair accident damage, correct corrosion, or modify the shell for performance and restoration work while keeping the structure safe and straight on a Porsche. Common problems include rust in sills, jacking points and arches, cracked or bent chassis rails after impacts, and misaligned panels from previous poor repairs.
Restoration Chassis / Repair Panels — Restoration and repair panels are used to cut out rusted or damaged sections and weld in fresh metal so classic Porsche shells can be preserved rather than replaced. Original panels often suffer from deep corrosion, distortion from jacking and accident damage, and old patch repairs that lead to MOT failures or poor panel gaps.
Front Section — Front section panels are fitted to repair crash damage, rust or previous poor repair work in the front structure and panel areas of a Porsche. Typical issues include bent crash structures, creased inner wings, rust around bumper mounts and battery trays, and misaligned front panels after accidents.
Engine Rebuild Parts — Engine rebuild parts are changed during a planned rebuild or when symptoms point to internal wear such as loss of compression, heavy oil use, persistent oil leaks, abnormal noises, or contamination found during inspection. On Porsche engines this can show up as low or uneven compression readings, smoke under load or overrun, metallic debris in the oil, low hot idle oil pressure, or overheating linked to internal friction.
- Before committing to a rebuild, use tests such as compression and leak-down, bore scoping, oil analysis and careful diagnosis of ancillary systems.
- When the engine is apart, it is common to renew chains, guides, tensioners, major seals, bearings where applicable, gaskets and key hardware to reduce the risk of repeat strip-downs.
Fuel System Parts — Fuel-system parts are replaced to restore correct fuel delivery, improve starting and idle quality, and prevent leaks that create safety and MOT or emissions issues on Porsche models. Hard starting, long cranking, hesitation on throttle, surging, flat spots, fuel smells around the car, damp patches under the vehicle, noisy pumps, poor fuel economy or failed emissions can all point to a tired fuel system.
- Stale fuel and water contamination can corrode components and clog filters or injectors, so many owners refresh lines, filters and key seals together on older cars or after long storage.
- Treat any fuel smell as urgent and inspect filler necks, breather lines, injector seals and hoses for leaks, replacing aged components in logical groups rather than one by one.
