About Nitron Automotive Range

Nitron Automotive Range

The Nitron Automotive Range at Design911 brings proven motorsport suspension technology to Porsche models, with kits designed to give precise, repeatable damping control for fast-road, track-day and competition use. Drawing on Nitron’s experience across championships worldwide, these systems are engineered to provide a focused, highly adjustable chassis setup while remaining usable on the road when configured sensibly.

Why do Nitron Automotive Range upgrades matter?

Nitron suspension is chosen by Porsche owners who want more control and adjustability than standard dampers typically provide. The combination of carefully specified spring rates and precision‑built dampers allows the car’s balance to be tuned for different circuits, tyres and driving styles while maintaining composure over demanding surfaces. Because the hardware is designed as a complete system, it offers a coherent platform for setup work, from baseline fast‑road settings through to more aggressive track configurations as your confidence and experience grow.

  • Give your Porsche a more tied‑down, confidence‑inspiring feel when driven quickly
  • Allow meaningful adjustment of damping to suit different roads, circuits and tyres
  • Support detailed chassis tuning alongside geometry and corner‑weighting
  • Provide durable, serviceable hardware suitable for repeated track-day use

Common options & kits

Individual replacement parts

Specific Nitron components such as dampers or ancillary hardware to refresh or repair an existing Nitron installation without replacing a complete kit.

  • Ideal when maintaining an already‑installed Nitron setup
  • Lets you address wear or damage on a single component
  • Helps keep overall upgrade costs under control

Matched sets or pairs

Front or rear pairs of dampers and related components supplied together so that both sides of an axle are renewed or upgraded at the same time.

  • Keeps left and right response consistent across the axle
  • Helps avoid uneven behaviour from mixed components
  • A sensible choice when carrying out staged suspension upgrades

Complete kits

Full Nitron suspension kits for Porsche models, typically combining height‑adjustable dampers with matched springs and supporting hardware, ready for installation and setup.

  • Everything specified together as a complete, balanced package
  • Reduces time spent sourcing compatible components individually
  • Ideal when moving to a fully engineered fast‑road or track‑focused setup for your Porsche

Brands available in this category

Nitron – Nitron has built its reputation over more than two decades of competition, with race wins, class victories and lap records in series around the world. All Porsche Nitron dampers are engineered, designed and manufactured in the UK, at the company’s headquarters in Oxfordshire. Each component is precision‑machined and subject to rigorous development and quality control, resulting in high‑quality, repeatable damping characteristics suited to serious fast‑road and track use.

When should you review or replace your Porsche Nitron Automotive Range setup?

Because Nitron systems are usually fitted to Porsches that see enthusiastic driving and regular track days, it is worth reviewing both condition and setup periodically. As mileage and use build up, oil and seals in the dampers can age, external adjusters may require cleaning and lubrication, and changes in tyres or alignment can justify a fresh baseline setup session.

  • The ride has become noticeably harsher or less controlled despite sensible settings
  • You hear knocking or clunking that may relate to top mounts, preload or worn components
  • Tyre wear has become uneven after lowering or geometry changes
  • The car feels nervous or inconsistent at speed compared with earlier in the kit’s life

If any of these apply, it is a good time to inspect the suspension, consider a service of the Nitron dampers, and have geometry and corner‑weighting checked so your Porsche continues to feel stable, predictable and enjoyable on road or track.
