Choosing the Right Fit for Your Porsche

Where Aasco 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 Aasco parts include sharper clutch engagement, reduced rotating mass, and improved durability for fast-road or track-focused Porsche use, often combined with clutch replacement to avoid repeat labour.
  • Common real-world triggers for replacement include clutch slip under load, high bite point, judder on take-off, or noise from worn flywheels, especially on higher-mileage cars or those used spiritedly.
  • Practical tip: some lightweight clutch and flywheel setups can increase drivetrain chatter; suitability for daily driving depends on the specific design and specification chosen.
  • Practical tip: when the gearbox is out, it is sensible to address related wear items and oil leaks such as the rear main seal to avoid future labour duplication.

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.

Engine Tuning — Engine tuning parts for Porsche are typically chosen to improve drivability, throttle response, or support hardware changes such as intake, exhaust, or forced induction where listed. They can also help refine running after repairs, provided the engine is mechanically healthy.

Clutches / Flywheels — Clutch and flywheel components for Porsche are replaced when there is slip, judder, noise, or during major drivetrain work. Upgraded parts are often selected to handle higher torque or give a sharper, more direct response where appropriate.

Gearbox / Transmission — Gearbox and transmission parts are used when there are issues such as whining, hard or noisy shifts, leaks, or when refreshing a high-mileage Porsche drivetrain. Correct compatibility with manual, Tiptronic, or PDK applications is essential.

Flywheel / Torque — Flywheels and torque-related components are replaced when there is judder, excessive play, heat damage, or when upgrading for different drivability characteristics on a Porsche. The right choice helps balance smoothness, response, and durability.

Special Offer Parts — Special offer parts are often used when tackling common Porsche wear items such as brakes, suspension, ignition, or service components, allowing several items to be refreshed together during planned maintenance.

  • Tip: before performance tuning, check compression or leak-down, fueling health, sensor data, and for any boost or vacuum leaks so that calibration changes are not masking underlying faults.
  • Tip: when replacing clutches or flywheels on a Porsche, consider a complete kit and, where applicable, new bolts and associated release components to make best use of the labour involved.
