Choosing the Right Fit for Your Porsche

Where Quaife 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 these parts include improving traction and stability, reducing inside wheelspin, and achieving more predictable power delivery, especially in wet or fast-road conditions.
• Common triggers for fitting include wheelspin, traction control cutting in frequently, and instability under throttle. Post-install noise or handling issues are often linked to incorrect oil, worn mounts, poor alignment, or underlying tyre/suspension problems rather than the differential itself.
• Practical tips: expect smoother, quieter operation than many plated LSDs in normal driving, use the manufacturer-recommended oil specification, and pair the differential with quality tyres and correct alignment to get the full benefit.

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.

Gearbox / Transmission — You change gearbox and transmission parts when you have shifting issues, noise, leaks, or you’re refreshing a high-mileage drivetrain. It’s also common during upgrades or when moving to stronger components; always match parts to your specific Porsche gearbox type and intended use.

Rear Differential — Rear differential components are replaced or upgraded to cure noise, leaks, excessive play, or to cope with higher torque in performance builds. A correctly specified unit helps restore smoothness and traction, especially when combined with appropriate mounts and drivetrain setup.

Steering Parts — Steering parts are changed to remove play, knocking and vague response, restoring precise, safe control. Choice of components can keep an original-style feel or give a slightly firmer, more direct setup, depending on how you use your Porsche.

Steering Racks — Steering racks are replaced or rebuilt to resolve fluid leaks, internal wear, or excessive play around the straight-ahead position. Selecting the right rack type and supporting parts (such as track rods and fluid) is key to consistent, confidence-inspiring steering.
