Function First Performance

Function First Performance for Porsche

We believe that every gear change presents an opportunity to deepen the mechanical connection between you and your car. To us, gear shifting is the paramount element of a distilled, analogue driving experience. Given its significance, each gear shift should feel solid, purposeful, and precise - rewarding you with a sense of satisfaction and accomplishment that delivers pure automotive joy. To that end, we meticulously dissect and perfect every single component that resides between the driver’s hand and the car’s transmission to deliver the ultimate in efficient and refined shifter feel for your Porsche.

A Quick Look at Function First Performance

Function First Performance 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 Function First Performance 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 improving handling and drivetrain feel, reducing unwanted compliance, and sharpening response under load.
• Common issues in this area can present as clunks on throttle transitions, wheel hop, vague response, or uneven tyre wear, with increased NVH possible when moving to stiffer mounts or bushes.
• Plan for a proper alignment check after chassis or suspension changes, as many real-world problems trace back to tired factory rubbers or incorrect geometry.
• When upgrading, change one area at a time and test, rather than stacking multiple modifications at once.

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 Rebuild Parts — Engine rebuild parts are typically renewed during a planned overhaul or when symptoms point to internal wear, such as loss of compression, heavy oil use, persistent internal leaks, abnormal noises, or contamination found during inspection. Because labour is the major cost, owners often replace chains, guides, bearings, gaskets, and fasteners while the engine is apart to improve post-rebuild reliability and reduce the risk of having to strip it again. Common symptoms include low or uneven compression readings, ongoing oil consumption or smoke under load or on overrun, metallic debris in the oil, low hot idle oil pressure, or knocking and rattling that worsen with RPM.

• Before committing to a rebuild, carry out structured checks such as compression and leak-down testing, borescope inspection, and oil/filter analysis.
• When the engine is already out, it is usually cost-effective to replace hard-to-access wear items like chains, guides, major seals, and key bearings at the same time.

Engine Mounts — Engine mounts are replaced when the rubber no longer controls drivetrain movement, leading to vibration, clunks, and a “loose” feel in the car. Many owners also choose different mount types to balance refinement against a more direct connection, especially on fast-road or track-focused Porsche builds. Excess vibration at idle, clunks on take-up of drive, thumps on gear changes, exhaust knocking, or visibly sagging or split mounts are all common signs that replacement is due, and neglected mounts can allow the engine to rock and stress hoses or exhaust joints.

• It is often wise to replace mounts as a pair, and to inspect gearbox mounts at the same time so the system works consistently.
• Be aware that firmer or performance mounts can increase NVH, even though they improve control and response.

Gearshift Control Parts — Gearshift control components (linkages, cables, bushes, selector parts) are replaced to restore precise, positive gear selection and cure vague or stiff shifting. On many Porsche models these external parts are checked and renewed before any decision is made to open the gearbox, because wear here is common and often responsible for poor shift feel. Symptoms can include a vague shift gate, difficulty selecting gears (especially 1st/2nd when cold), popping out of gear due to poor engagement, or excessive play at the lever that can lead to mis-shifts.

• If the clutch system is healthy and selection is vague across multiple gears, the linkage and bushings are a strong area to investigate.
• Some systems allow adjustment, but worn components generally need replacement rather than repeated re-setting.

Suspension Upgrades — Suspension upgrades are chosen to improve body control, cornering balance, and steering response, or to tailor a Porsche for specific use such as comfortable road driving, fast road, or track days. Owners typically change components or specifications based on the ride height they want, how much adjustment they need, and how firm they are comfortable with the car feeling in daily use.

• Not all upgrades automatically make the car feel better; matching springs, dampers, and bushes and then setting geometry correctly is crucial.
• Budget for professional alignment (and, where relevant, corner weighting) after changes, and start with a clear goal so the car ends up riding and handling as intended.
