SmartTop
SmartTop for Porsche
SmartTOP is a premium line of comfort and convenience modules engineered by Mods4Cars to enhance convertible driving experiences. Designed for a wide range of convertible vehicles — including BMW, Mercedes-Benz, Porsche, Ford, Nissan, Mini, and more — SmartTOP modules add smart, user-friendly functions that improve how your convertible top operates. With SmartTOP installed, drivers gain remote convertible top control via OEM key fob, one-touch automatic top operation (no need to hold the switch), and the ability to open and close the roof while driving at low speeds — all without modifying factory wiring thanks to a plug-and-play installation system. Beyond core roof control, SmartTOP modules offer a suite of additional comfort features such as programmable window behaviour, remote window operation, custom top switch logic, hazard signal options during remote operation, and automatic configuration that doesn’t interrupt roof movement when starting or stopping the engine. Built with high-quality electronics and backed by free USB-update support, SmartTOP modules transform everyday convertible use into a smarter, more convenient and enjoyable driving experience — perfect for owners who value both performance and practicality.
A Quick Look at SmartTop
SmartTOP 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 SmartTop 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 people replace or add these modules include gaining one-touch roof operation, using the roof at low speeds (where supported), adding remote functions and making daily convertible use simpler.
- Common symptoms to address first are roof not operating correctly, error messages, or intermittent behaviour caused by existing faults or low battery voltage.
- Before fitting, check battery health, repair any roof system faults and scan for fault codes so existing issues are not blamed on the module.
- Installation is usually reversible if original connectors are retained and instructions are followed carefully.
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. Common problems include rust in sills and arches, bent rails after impacts, and past poor repairs causing misaligned panels.
Roof - Cabrio / Targa / Coupe / Speedster — Roof components for different Porsche body styles are renewed to fix leaks, wind noise, worn mechanisms or to restore structure and weather protection. Typical issues include water leaks, wind whistles, worn seals, stretched fabrics and noisy or slow operation.
Cabrio — Cabrio roof parts are changed to eliminate leaks, faded or torn fabric and poor folding behaviour so an open-top Porsche stays weather-tight, quiet and smart. Symptoms include cloudy rear windows, failed tension cables, worn seals and slow or non-functioning hydraulic or electric mechanisms.
Electrical & Relays — Electrical and relay components are replaced when switching, protection or power delivery becomes unreliable, causing intermittent faults or loss of key functions. Owners often renew parts after “no-start”, random warning lights, blown fuses, or repeat relay and switch failures due to heat and vibration.
SmartTop Control Units — SmartTop-style roof control modules are replaced when roof or window convenience features become unreliable, when older or generic modules cause battery drain, or when owners want updated functions such as refined remote operation and one-touch behaviour. They are also removed or bypassed for diagnosis if they interfere with factory locking or alarm systems.
