Quantum Racing

What Quantum Racing does

Quantum Racing Services Ltd. is a privately held UK manufacturer of custom-built racing shock absorbers and suspension systems, founded in 1989 and headquartered in Pulborough, West Sussex. The company operates with a small team of 8 employees under founder-owner Patrick Murphy, a former number one mechanic for Benetton Formula One, and serves motorsport customers across professional racing, historic/classic car competition, and club-level racing. Its core product platform is the Quantum Zero family of gas-pressurized monotube shock absorbers — comprising Zero (non-adjustable), One.Zero (single adjuster), and Two.Zero (independent two-way compression/rebound adjustment) variants — supplemented by the Atomic twin-tube line for FIA Appendix K-compliant historic racing. Supporting products include 2.25-inch ID coil-over springs (50-2000 lb/inch rates) and in-house servicing options (interim £102, major £191, dyno testing £39-£70).

The business model is built on made-to-order manufacturing with 3-4 week lead times, distributed primarily through direct sales (phone +44 1798 875 199 and email) to UK and international customers. Hardware unit pricing ranges from £318 for a single Zero damper to approximately £4,948 for premium two-way coilover kits. In-house CNC manufacturing from steel bar and tube enables bespoke configurations, remanufacturing of historic F1 suspension components, and custom applications outside motorsport — exemplified by a partnership with Small Robot Company supplying dampers for autonomous agricultural robots. Distribution is direct-to-consumer with selective international shipping; branded merchandise is sold via a small e-commerce storefront. The company has historically supplied teams across Formula 1, Formula 3, Formula Ford, Japanese GT, and various UK club racing categories, with marquee historical results including David Coulthard's 1991 British F3 victory at Donington Park with Paul Stewart Racing.
