Kits for Porsche
Design911 offers an extensive selection of package deals for Porsche parts, providing an ideal solution for Porsche enthusiasts looking to upgrade, maintain, or personalise their vehicles. These packages are thoughtfully curated to include complementary components, helping with compatibility and overall cost-effectiveness.
A Quick Look at Kits
Kits 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 Kits are listed for Porsche, use the supplied model coverage and OE references to confirm suitability. Check details that commonly affect fitment such as model year, axle or side, and any option codes or connector types where relevant.
- Typical reasons people choose kits include wanting all the right Porsche parts in one order, reducing the risk of missing seals, clips, or one-time-use fixings, and saving workshop time.
- Kits help ensure matched components (for example, brake refresh kits, service kits, or suspension refresh kits) so parts work together as intended.
- Common real-world triggers include repeated failures because a small supporting part was not replaced, mixed part revisions, or mismatched specification between components.
- If problems occur, they are often traced to incorrect vehicle selection, old core components not addressed, or installation shortcuts rather than the kit itself.
- Before you start work, compare the kit contents with the Porsche PET diagram and your job list so you know exactly what is included and what may still be needed.
- Always confirm whether kits are vehicle-specific, and check if bolts, clips, fluids, and other one-time-use hardware are included or need to be added separately.
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.
Brakes — Brake components are renewed to restore stopping performance, address wear or upgrade a Porsche for fast road or track use. Common symptoms include vibration under braking, increased stopping distances, squealing, pulling to one side, warning lights and visible wear to discs and pads.
- Check whether new fitting kits and wear sensors are included or should be added separately.
- Confirm if parts are OE-equivalent replacements or higher-friction performance upgrades before ordering.
Brake Pads Packages — Brake pad packages group matched front and rear sets, making it easier to renew all pads at once for consistent feel and balance across the axle. Worn pads can cause squealing, low pedal feel, longer stopping distances and may score discs if run down to the backing plates.
- Verify whether the package covers front, rear, or both axles and whether it is a standard or performance compound.
- Check the contents list for anti-squeal shims, hardware and any wear sensors you may want to replace at the same time.
Gearbox / Transmission — You change gearbox and transmission parts when you have shifting issues, noise, leaks, or you are refreshing a high-mileage drivetrain. It is also common during clutch upgrades or ratio changes. Typical symptoms include whining in a specific gear, crunching on shifts, or difficulty selecting gears, as well as leaks at seals or casing joints.
- Not all noise or poor shifting means the gearbox itself is failing—mounts, linkage, clutch, and oil condition can produce similar symptoms.
- Using the correct-spec gearbox oil and refreshing it is often a sensible first step before major work.
Service Parts — Service parts are replaced as routine maintenance to keep the engine and systems reliable, efficient, and protected. Doing this on schedule reduces wear, helps prevent breakdowns, and maintains performance—especially on older Porsche models where neglected servicing can quickly lead to costly repairs. Symptoms prompting attention include hard starting, rough idle, reduced fuel economy and poor throttle response.
- Both OEM and reputable aftermarket parts can be suitable—always match the correct specification for your Porsche.
- Keeping a clear service log helps diagnostics later and can support the car’s resale value.
Service Kits — Service kits bundle the correct parts for a routine Porsche service into one package, reducing ordering mistakes and ensuring you can reset the car to a known maintenance baseline. They are ideal when catching up on overdue work or planning regular servicing to a consistent standard. Symptoms leading to a full kit are often general, such as sluggish running, inconsistent idle, poor economy, or increased engine noise from old oil and filters.
- Service kits typically include filters and key consumables, but contents vary—check the list carefully and add any extra items you want to replace while access is good.
- Kits are usually specific to model, year and engine, so confirm these details before ordering.

Complete Water Pump Kit – Water Pump, Thermostat,
Serpentine Belt & Gaskets for a Full Cooling System Refresh
This complete water pump kit includes a new water
pump, thermostat, drive (serpentine) belt and the required gaskets for both the
pump and thermostat housing.
Fits:
- Porsche 991.1 Carrera C2S 3.8L (400Bhp) 2012-16
- Porsche 991.1 Carrera C4S 3.8L (400Bhp) 2012-16
Designed as a comprehensive cooling system service package, it ensures correct coolant circulation, accurate temperature regulation, and reliable accessory belt operation. Ideal for preventative maintenance or full cooling system repair, this kit provides everything needed to restore confidence in your Porsche’s engine cooling performance.
The water pump continuously circulates coolant through the engine and radiators, while the thermostat regulates operating temperature and ensures the engine warms up properly. The serpentine belt drives essential accessories—including the water pump—so replacing all these components together ensures long-term reliability and prevents future breakdowns.
What This Complete Water Pump Kit Does
This cooling system service kit:
- Replaces
the water pump to restore proper coolant flow
- Includes
a new thermostat for accurate temperature control
- Supplies
a fresh serpentine belt to ensure reliable accessory drive operation
- Comes
with all required gaskets to prevent leaks during installation
- Improves
cooling efficiency, reducing the risk of overheating
- Ensures long-term reliability with coordinated component replacement
- Perfect for workshop servicing, DIY maintenance or high-mileage cooling system refreshes.
Why Water Pumps, Thermostats & Belts Fail
Common failure points include:
- Bearing
wear inside the water pump, causing leaks or noise
- Impeller
degradation, reducing coolant flow
- Thermostat
sticking, leading to overheating or overcooling
- Serpentine
belt cracking, glazing or stretching
- Coolant
contamination, accelerating component wear
- Heat cycling, which weakens gaskets and housings
Cooling failures can cause warped cylinder heads, engine misfires or complete engine failure if not addressed promptly.
Why These Components Should Be Replaced Together
Replacing the pump, thermostat and serpentine belt as a set
ensures:
- Restored cooling performance across the entire system
- Correct belt tension and accessory drive function
- Reduced labour costs by avoiding repeat disassembly
- Balanced
longevity, as all components age similarly
- Prevention
of leaks, thanks to new gaskets and seals
- Peace of mind for daily driving, long trips or track use
This kit offers the most reliable and cost-effective approach to cooling system maintenance.

- Perfect for workshop servicing, DIY maintenance or high-mileage cooling system refreshes.
Why Water Pumps, Thermostats & Belts Fail
Common failure points include:
- Bearing
wear inside the water pump, causing leaks or noise
- Impeller
degradation, reducing coolant flow
- Thermostat
sticking, leading to overheating or overcooling
- Serpentine
belt cracking, glazing or stretching
- Coolant
contamination, accelerating component wear
- Heat cycling, which weakens gaskets and housings
Cooling failures can cause warped cylinder heads, engine misfires or complete engine failure if not addressed promptly.
Why These Components Should Be Replaced Together
Replacing the pump, thermostat and serpentine belt as a set
ensures:
- Restored cooling performance across the entire system
- Correct belt tension and accessory drive function
- Reduced labour costs by avoiding repeat disassembly
- Balanced
longevity, as all components age similarly
- Prevention
of leaks, thanks to new gaskets and seals
- Peace of mind for daily driving, long trips or track use
This kit offers the most reliable and cost-effective approach to cooling system maintenance.
