About Kits

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.

We supply high-quality replacement oil tank hardware crafted to the same dimensional standards as the original Porsche components. Manufactured from durable, corrosion-resistant materials, these washers are designed to withstand continuous exposure to oil, heat, and pressure—making them ideal for classic Porsche maintenance and restorations.

What Does the Oil Tank Mounting Kit Do?

Each component in this kit works together to secure the oil tank and maintain stable dry-sump operation.

Core Functions:

  • Provides secure mounting and vibration resistance for the oil tank.
  • Ensures even load distribution across mounting points.
  • Maintains tank alignment for correct oil line routing.
  • Prevents leaks by keeping the tank firmly compressed against mounting surfaces.
  • Supports lubrication stability during high-performance driving.

These hardware components are crucial for maintaining the stability and efficiency of Porsche’s iconic dry-sump system.

Why Do Oil Tank Mounting Components Fail?

Over decades of use—especially in classic Porsches—mounting hardware faces extreme conditions including heat, vibration, oil exposure, and corrosion.

Product Information
Product Information
Inlet / Intake Manifold Gasket, SET OF 6.
Flat intake manifold gasket it used between the intake manifold runners and the cylinder head on Porsche flat-six engines. Each gasket seals one intake port pair; a complete engine typically uses six of them.

Fits:
Porsche 911 1974 - 1983  - 6pcs required


Diagram ref no 7.

This set of six intake manifold gaskets provides a complete gas-tight seal between the intake manifold and cylinder heads, ensuring that all air entering the engine follows the correct metered path through the CIS or fuel-injection system. By eliminating air leaks at the manifold flanges, these gaskets help maintain proper air–fuel mixture, support smooth idle and drivability, and prevent lean conditions that can raise combustion temperatures.

Over time, manifold gaskets naturally harden, shrink or crack from heat cycles, fuel vapour exposure and age. When this happens, the engine may draw in unmetered air, resulting in rough idle, poor cold running, lean mixture symptoms, hesitation or flat spots during acceleration. Vacuum leaks also make tuning more difficult and can lead to increased fuel consumption. Replacing old gaskets with a fresh set of six restores full sealing integrity, stabilises idle and mixture control, and helps the engine operate as intended.

When to replace
You should replace the full set of inlet manifold gaskets if:
 You are rebuilding or refreshing the top end of the engine.
 There are suspected vacuum leaks around the intake manifold.
 The engine shows rough idle, hunting, or lean-related symptoms not traced to other components.
 The existing gaskets are cracked, brittle, or oil/fuel soaked.
 You are upgrading, servicing or adjusting the CIS / intake system on a classic 911 or 930.

Front & Rear Shock Absorbers package, SET OF 4.
This OE Match full suspension package provides all four replacement shock absorbers for PASM-equipped cars, featuring built-in cancellation resistors to prevent dashboard errors.  Replacement for adaptive damping system on Porsche 991.1 Turbo / Turbo S (2014–2016), Not suitable for GT2 models.

The kit includes two front replacement PASM shocks (OE ref no: 991343045A5) and two rear replacement PASM shocks (OE ref no: 99133305326)  These replacement shock absorbers are compatible with PASM-equipped cars and include built-in cancellation resistors to eliminate dashboard errors. They effectively bypass the Active Suspension Management system, allowing the vehicle to function as though it has standard suspension installed.

Fits:
Porsche 991.1 Turbo / Turbo S 2014 - 2016
Replacement for cars with option codes:
475 - "PASM" Electronic Damper Control
352 - Electronic Damper Control For PASM And PDCC

Diagram ref no 1

  • These shock absorbers are not PASM dampers and do not offer PASM-adjustable damping.
  • They are designed as standard replacement units with built-in electronics to cancel PASM fault warnings.
  • For correct functionality and proper vehicle handling, they must be installed as a full set of four (2 × front shock absorbers + 2 × rear shock absorbers
  • Mixing PASM units with OEMatch replacement units is not permitted and may result in suspension imbalance or fault messages.       

Each damper is manufactured to be a direct-fit replacement shocks for PASM vehicles, complete with integrated cancellation resistors so you can upgrade with zero dashboard errors or warning lights, ensuring seamless communication with the PASM control module. 

This set is ideal for high-mileage cars, leaking or weakened PASM dampers, or anyone seeking to restore the driving precision, comfort, and stability of the 991 Turbo platform.

As PASM dampers wear, internal valves weaken, seals leak and electronic reaction time slows - reducing the system’s ability to adjust damping. This results in instability, harsh ride quality, reduced grip and unpredictable handling. Replacing all four shocks direct-fit replacement shocks for PASM vehicles, complete with integrated cancellation resistors so you can upgrade with zero dashboard errors or warning lights.

When to replace:
 PASM warning messages or inconsistent adaptive damping
 Excessive body movement, squat, dive or rolling
 Harsh, bouncy or unstable ride on bumps
 Fluid leakage from any shock absorber
 Rear instability or poor steering precision
 Uneven or accelerated tyre wear
 High-mileage suspension (>60k miles) or full chassis refresh

Product Information
Product Information
Original FRONT and REAR shock absorbers PACKAGE, SET OF 4.
These replacement shock absorbers are compatible with PASM-equipped cars. 

Fits:
Porsche 958.1 Cayenne (92A) 2011 - 2014
Replacement for cars with Suspension/Dampers, Standard 2 PASM (option code: 1BH)
Replacement for cars with Comfort Suspension/Damping, PASM (option code: 1BZ)

This package includes:
1 ×  958413031 - OE Front Left Shock Absorber
1 ×  958413032 - OE Front Right Shock Absorber
2 ×  958513029C - OE Rear Shock Absorbers (left + right)

  Suspension Position: Full-axle coverage - replaces both front shock absorbers and both rear shock absorbers.
  • They are designed as standard replacement units.
  • For correct functionality and proper vehicle handling, they must be installed as a full set of four (2 × front shock absorbers + 2 × rear shock absorbers)      

  Function of the set: The shock absorber set works together to smooth out bumps and road imperfections, keeping the tyres firmly in contact with the surface for consistent grip. By controlling body roll, pitch and dive during braking, acceleration and cornering, the dampers help maintain stability and predictable handling. As a complete set, they restore the vehicle’s original ride comfort, balance and suspension geometry.

Replace the shock absorbers when the ride becomes noticeably bouncy, harsh, or unstable, or when the vehicle no longer absorbs bumps as smoothly as it once did. You should also install new dampers if the car shows excessive body movement during braking or cornering, or if tyre wear and alignment issues begin to appear. High-mileage vehicles, or those undergoing broader suspension work, will also benefit from replacing all four shocks at the same time.  

Why replacement matters:
  Restores proper damping control and improves overall handling
  Ensures stable tyre contact for better grip and braking performance
  Reduces body roll, pitch and dive for safer, more predictable dynamics
  Prevents uneven tyre wear caused by weak or failed shocks
  Enhances driving comfort, stability and long-term suspension health.

What’s Included:

• 2x 99134104306/3 – OE Match Front Control Arms
These front lower control arms (wishbones) are manufactured to OE match specification, ensuring the same geometry, fit and performance as the original Porsche part. They provide stability, absorb road forces and help maintain accurate wheel alignment.

• 2x 99134105306/3 – OE Match Front “Coffin Arms”
Named for their distinctive shape, these arms are critical for controlling camber, caster and steering behaviour. Worn coffin arm bushes are a common cause of knocks, vibration and vague steering response — replacing them restores crisp, precise front-end dynamics.

Genuine Porsche Fitting Kit (bolts and nuts) A complete set of new Porsche fasteners for correct installation. Suspension bolts and lock nuts should not be reused, as they are torque-to-yield and essential for maintaining clamping force and safety.

This complete kit renews the entire lower front control arm assembly, allowing you to:
•  Restore factory steering precision and handling stability
•  Correct alignment issues caused by worn bushes or elongated joints
•  Eliminate knocking, squeaking or vibration from the front suspension
•  Ensure safe and reliable installation using fresh genuine Porsche hardware.

Front control arm bushes and ball joints wear over time due to road impacts, driving style and age. Symptoms include:
• Steering play or “loose” front end feel
 Uneven tyre wear
 Vibration or knocking over bumps
 Poor tracking or pulling to one side
 Instability under braking

Replacing all four arms together ensures even wear, consistent geometry, and the best long-term results, especially when pairing with a fresh alignment.

Product Information
Control arm lower, Rear.
This OE Match suspension set includes two rear lower control arms (2 × 98733104304), providing a complete left-and-right replacement for the rear axle of Porsche 987 Boxster and 987 Cayman models. These arms are engineered to replicate the geometry, strength, and bushing characteristics of the original Porsche components, ensuring precise wheel alignment, stable handling, and predictable chassis behaviour.
SET OF 2 - for left and right side.

Fits:
Porsche 987.1 Boxster 2005 - 2008
Porsche 987.2 Boxster 2009 - 2012
Porsche 987C.1 Cayman 2005 - 2008
Porsche 987C.2 Cayman 2009 - 2012

This set is ideal for vehicles showing rear-end instability, knocking noises, or alignment issues caused by aged or worn control arm bushings.

•  Part Numbers / Cross-References: 98733104304 (current), 98733104302 / 98733104303 (previous numbers)

• Position: Rear lower control arm / lateral link - connects rear axle assembly to chassis/subframe, controlling wheel lateral and longitudinal position under dynamic loading.

 Functions: Maintains correct wheel alignment geometry under load, ensures stable rear-end handling, helps manage camber and toe changes, absorbs suspension loads, supports consistent tyre contact and handling predictability.

The rear lower control arms maintain correct camber and toe alignment during suspension travel. They stabilise the rear axle under dynamic load and help ensure consistent tyre contact and grip. As a matched pair, they work together to deliver the balanced handling and responsiveness expected from a Porsche mid-engine chassis.

Benefits of replacing as a pair:
 Restores identical suspension behaviour on both sides
 Ensures consistent camber and toe alignment
 Eliminates uneven tyre wear caused by mismatched bushings
 Improves high-speed stability and cornering predictability
 Ideal for full rear suspension refresh or alignment correction

With time, the bushings and joints inside these arms deteriorate, causing unwanted movement, clunks, instability and poor alignment. Replacing both arms ensures complete restoration of rear suspension accuracy, improving handling sharpness, road feel and overall safety.

When to Replace:
 Knocking or clunking noises from the rear over bumps
 Excessive play in rear suspension arms during inspection
 Uneven or premature rear tyre wear
 Alignment cannot be maintained (camber/toe constantly shifting)
 Rear-end feels unstable during cornering or acceleration
 Performing a full suspension overhaul

Perfect for eliminating front-end (or rear-end) clunks, correcting wandering steering, or resolving alignment issues caused by aged bushings or worn ball joints, this OE-Match set offers outstanding performance and value.

Benefits of replacing as a pair:
 Ensures equal bushing compliance on both sides
 Restores symmetrical steering feel and chassis response
 Improves straight-line stability and turn-in precision
 Eliminates uneven tyre wear caused by mismatched suspension parts.

As the original control arm bushings age, they soften, crack or shift under load. This leads to vague steering, instability over bumps and difficulty maintaining alignment. Replacing both arms ensures the suspension operates as intended, improving safety, ride quality and cornering confidence.

When to replace:
 Knocking or clunking noise from the front end (rear end)
 Steering feels loose or unstable
 Uneven tyre wear or alignment that won’t hold
 Excessive play detected in ball joints
 Visible bushing deterioration or cracking.
