DesignTek Performance Parts for Porsche

DESIGNTEK — PERFORMANCE ENGINEERED
Porsche performance upgrades for road, fast road and track. Explore DesignTek exhaust, suspension, braking, induction, wheel fitment, chassis and driver-focused upgrades for classic and modern Porsche models.
Better sound. Better stance. Better response. Better control.

The DesignTek story

DesignTek is Design911’s Porsche-focused performance brand, created for drivers who want to get more from their car. Its products are selected and developed to enhance the driving experience, whether through a sharper exhaust note, shorter gearshift, more controlled suspension or a purposeful change in stance. With around 500 products, the range has grown to cover straightforward fast-road upgrades alongside more focused track and motorsport components for classic and modern Porsche models.

Why choose DesignTek for your Porsche

DesignTek occupies the quality aftermarket and performance-upgrade tier, providing Porsche-specific alternatives when an owner or workshop wants to go beyond a standard replacement component. The range supports different objectives, from restoring clean airflow and improving driver feel to developing a more focused road, track or competition car. DesignTek is not about modifying a Porsche simply for the sake of it; it is about choosing considered upgrades for the way the car will be driven. Design911 specialists can help customers compare applications, specifications and related components before selecting an upgrade.

  • Porsche-focused applications rather than a predominantly universal range
  • Exhaust, suspension, braking, induction, chassis, wheel-fitment and driver upgrades
  • Coverage extending from classic air-cooled 911 models to modern Porsche applications
  • Options for road, fast-road, track and competition use
  • Direct-fit and adjustable products where specified for the application
  • An accessible route from standard replacement parts to more specialised performance equipment

DesignTek performance ranges

The Design911 DesignTek range covers the principal areas used to change how a Porsche sounds, sits, responds and feels. Always confirm the listed model, year, position, OE reference, connector type and included fittings before ordering.


Performance Exhaust Exhaust is at the heart of the DesignTek range, with individual components and complete performance systems for classic and modern Porsche models.

  • Valvetronic switchable systems, sports silencers, rear boxes, manifolds, headers, downpipes, sports catalytic converters and catalyst-bypass or decat pipes
  • Classic 911 heat exchangers, stainless-steel systems and carbon-fibre or performance exhaust tips
  • Selected listings specify SUS304 or T304 stainless steel, high-flow 200-CPSI or 300-CPSI catalysts, switchable valves and carbon-fibre tailpipes
  • Options address exhaust character, flow, appearance and complete system upgrades; catalyst-bypass products are intended for appropriate track-focused application.


Performance Suspension DesignTek suspension products are intended to strengthen the connection between the driver, chassis and road, with choices spanning road use to competition.

  • DesignTek Performance Springs, lowering spring kits, adjustable ride-height suspension and D220 coilover systems
  • Selected D220 applications include adjustable damping, while the specialist Asphalt Rally range provides greater adjustment for competition use
  • Road-focused springs provide a lower stance and increased control where specified
  • Inspect worn mounts, bushes and adjacent components, and complete the required alignment and torque procedures after installation


Performance Braking DesignTek braking products support Porsche builds requiring replacement components or a more substantial braking upgrade.

  • Carbon-ceramic replacement brake discs and compatible brake pads for specified Porsche applications originally equipped with ceramic systems
  • Performance brake components, GT-style packages, Big Red kits and larger upgrades for selected classic and modern Porsche platforms
  • Check disc size, caliper type, wheel clearance and the complete application before selecting an upgrade


Performance Airflow & Induction DesignTek airflow products range from direct-replacement filters to complete intake systems and supporting components.

  • Cold-air induction kits, high-flow intake systems, intake hoses, selected plenums and associated airflow upgrades
  • Dedicated induction products are offered for selected Boxster and Cayman applications, alongside systems for other Porsche generations
  • Maintain proper sealing, sensor positioning and sensible intake temperatures to avoid unmetered air, poor idle, warning lights, heat soak or inconsistent response
  • Check mounting security and routing after installation to minimise rattles, hot-air ingestion and water exposure


Performance Air Filters DesignTek offers replacement and performance air filters for routine servicing, fast-road use and wider tuning packages.

  • Applications include classic 911, 996, 997, 991 and 992 models, with further coverage across the Porsche range
  • Selected filters use washable, reusable cotton-gauze media designed to balance filtration with increased airflow
  • Clean the airbox and make sure the filter seal is seated evenly; a poor seal can allow dust and debris into the intake
  • Replace filters more frequently in dusty or harsh conditions and avoid over-oiling reusable filters where airflow sensors are fitted


Wheel Fitment & Stance DesignTek wheel-fitment products allow owners to refine wheel position and stance, particularly alongside lowering springs or other suspension changes.

  • Hub-centric wheel spacers, spacer kits, Black Edition spacers, wheel bolts, extended bolts and fitting hardware
  • Selected hub-centric spacers use anodised 6061-T6 aluminium construction
  • Confirm spacer thickness, wheel and tyre clearance, bolt or stud length and the specified tightening procedure


Chassis & Handling Chassis reinforcement can complement upgraded suspension, tyres and brakes by creating a more focused connection between the car and driver.

  • Front and rear strut braces in selected alloy and carbon-fibre designs
  • Applications include classic 911, 964, 993, 996, 997, Boxster and Cayman models
  • Supporting chassis and suspension upgrades should be chosen as part of a balanced package for the intended road or track use


Driver & Track Driver-focused products change the points of interaction used every time the Porsche is driven.

  • Short-shift kits, performance gearshift components, alloy pedal and footrest kits, motorsport harnesses and selected competition equipment
  • Short-throw shifters are offered for selected 986, 987, 996 and 997 applications
  • The range includes a six-point FIA-approved race and rally harness option
  • Confirm installation requirements and compatibility with seats, mounting points and other safety equipment


Engine Tuning DesignTek engine-tuning components support improved drivability, throttle response and power delivery, or complement compatible intake, exhaust and airflow changes.

  • Resolve mechanical faults before tuning rather than masking hesitation, flat spots, rough running, warning lights or inconsistent boost with new hardware or calibration
  • Check compression, fuel delivery, sensor data, oil and coolant temperatures, and boost or vacuum leaks before tuning work
  • Review supporting hardware and use a calibration appropriate to the complete engine specification


Performance Service Parts DesignTek service products support scheduled maintenance and can combine routine replacement work with selected performance-filter options.

  • Use the correct specifications for filters, plugs, fluids, belts and related service components, and keep a clear replacement record
  • Shorten service intervals where a Porsche is regularly used for short journeys, in harsh conditions or under sustained hard use
  • Investigate leaks, knocks, worn mounts, poor ride control, restricted intake noise, intermittent operation, reduced fuel economy and warning lights rather than replacing unrelated parts
  • Inspect adjacent components and confirm whether seals, fittings and hardware are included to reduce repeat labour


Explore the DesignTek range

Choose how you want your Porsche to feel: more sound, a lower and more purposeful stance, sharper handling, greater confidence under braking, cleaner airflow or a more involving connection between driver and car.

Exhaust catalytic converter.

Fits:

Our cat is made up of the following components:

  • Ceramic monolith of a honeycomb design to allow free air flow and maximum surface area, coated with precious metals to enable the conversion of gasses that pass through it
  • Interam matting to hold the monolith in place. The matting expands when exposed to heat to supply the pressure needed to keep the monolith secure
  • A grade 409 stainless steel can (or housing) to provide protection and enable the cat to be built into the exhaust system. 409 grade can contain upto 90% iron and will be prone to rust. It still has higher rust-resistant properties than mild steel.
