A Quick Look at DDM

DDM 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 DDM 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.

• Typical reasons to choose these parts include repairing known wear items, refreshing tired components, and making sensible upgrades while keeping the car usable day to day.
• Common triggers to replace parts include noise, looseness, intermittent operation, and premature wear, especially where underlying issues or poor installation have been present.
• Watch for symptoms such as rattles, vibration, or components that no longer operate consistently, and always address corrosion or related worn parts at the same time.
• Check product notes for whether a part is OE-spec or an alternative, and confirm if any extra hardware or installation accessories are recommended.
• Where possible, plan to fix the root cause (such as worn mounts, damaged wiring, or misalignment), not just the one failed part, to avoid repeat issues.

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.

Interior & Accessories — Interior parts are replaced to refresh worn touch points, fix broken trim, or restore factory fit and function during a refurbishment. Accessories are also used to improve usability (storage, protection, convenience) without altering the car’s character. For classics, replacing tired interior components can noticeably lift the whole cabin feel. Common symptoms include sticky switches, broken clips, rattles, sagging trim, worn surfaces, faded plastics, and broken hinges or handles.

• Always check whether parts are specific to certain model years or interior options, as small changes in clips and finishes can affect fit.
• Use proper trim tools and replace missing clips or fasteners during installation to minimise new rattles.

Steering Wheels Parts — Steering wheel parts and accessories such as boss kits, spacers, horn components, trim rings, and switches are replaced to restore proper function after wear, damage, or incorrect previous installations. They are also needed when retrofitting a different steering wheel so that the supporting hardware matches. Getting these smaller parts right helps prevent rattles, warning lights, and poor ergonomics. Common defects include horn faults, a loose wheel, creaks, airbag warnings (where applicable), and non-functioning buttons.

• Boss kits and many steering components are model-specific, so always confirm spline pattern and required depth for your Porsche.
• Align the wheels straight ahead, mark the steering shaft, and torque all fasteners to specification to maintain correct steering alignment and function.
