Spec for Porsche

Spec parts for Porsche models from Design911.

A Quick Look at Spec

Spec 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 Spec 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 Spec clutch parts include handling higher torque on tuned Porsches, improving heat resistance, and matching the clutch to how the car is driven (street versus track).
• Common issues that lead to replacement include judder, chatter, heavier pedal feel, or driveline vibration, as well as problems caused by poor bedding-in, worn hydraulics, or oil contamination.
• Watch for symptoms such as clutch slip under load, harsh engagement, or drivetrain shudder; these can indicate that the current clutch or flywheel is no longer suited to the car’s use.
• Before fitting new Spec clutch components, fix any oil leaks and follow the recommended bedding-in procedure to avoid glazing and premature wear.
• When upgrading to higher-capacity clutch parts, consider drivability; some more aggressive setups bring extra noise, vibration, or effort at the pedal.

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.

Gearbox / Transmission — You change gearbox and transmission parts when you have shifting issues, noise, leaks, or you’re refreshing a high-mileage drivetrain. Where Spec components are listed for Porsche, they can be used as part of clutch, flywheel, or wider transmission work to restore smooth operation or support higher loads.

• Check basics first: correct oil, mounts, and linkage, as these can mimic gearbox faults before you commit to major component changes.
• Avoid driving for long with a noisy or slipping transmission, as underlying wear can escalate into more extensive damage.

Clutch Kits - High Performance — High performance clutch kits from Spec are typically chosen when a Porsche has been tuned or is used hard, and an OE clutch may begin to slip. They focus on higher torque capacity and better heat tolerance, with a trade-off of potentially firmer engagement and more driveline feedback.

• When choosing a kit, match the friction material and design to how the car is actually used so that daily driving remains manageable where required.
• Remember that clutch upgrades will not cure gear selection issues if the root cause lies in linkages or internal gearbox wear.

Flywheel / Torque — Spec-related flywheel choices come into play when a worn or heat-affected flywheel is found during clutch work, or when moving from dual-mass to single-mass for a more direct motorsport-style setup. The correct flywheel pairing is important for drivability, noise levels, and clutch life.

• Inspect for excessive play, cracks, or hot spots; a compromised flywheel can quickly damage a new clutch.
• Follow the recommended bolt specification and torque procedure whenever a flywheel is refitted or replaced.
