What Design 911 does
Design 911 (legally trading as Sideline Design Ltd) is a UK-based independent specialist in Porsche parts and accessories, operating since approximately 2000 and headquartered at 51 Tallon Road, Brentwood, Essex, with a registered office in London (NW11 8SR). The business holds more than 500,000 Porsche parts in stock across two strategically located distribution centres — in Brentwood, UK, and the Netherlands — and ships to over 180 countries worldwide. Its catalog spans the full Porsche model range from classic air-cooled vehicles (356, early 911) through modern water-cooled models to the electric Taycan and Macan-e, covering brakes, chassis and bodywork, electrical components, exhausts, wheels and tyres, suspension, performance tuning software, accessories, and a lifestyle/clothing line.
The company runs a dual-channel go-to-market model. The retail channel is a direct-to-consumer e-commerce platform (design911.com) targeting individual Porsche owners and enthusiasts, offering self-serve purchasing with basket saving, order tracking, free UK delivery over £200, and global DAP shipping. The trade channel is the Design911 Trade Partners Programme, a dedicated B2B portal serving garages, workshops, body shops, and resellers with exclusive wholesale pricing, account management from a named trade sales manager, and preferential delivery terms. An own-brand aftermarket line, OE Match, supplies replacement components positioned to meet or exceed factory standards at lower price points than OEM.
Design 911 is structured as an employee-owned company, with 75% of the business held by staff following a transfer of ownership from the founder. The business claims to be the largest independent Porsche parts specialist serving trade customers in the UK, supported by 110,000+ lifetime customers and positive Trustpilot reviews. Revenue is generated entirely through unit-priced, pay-as-you-go transactions on parts and accessories across both retail and trade tiers, with no subscription, recurring licensing, or contractual enterprise revenue disclosed.

Design 911 competitors and assessment
Company assessmentDirect peers
- Pelican Parts: US-based specialist in Porsche and Mercedes-Benz parts with deep technical content, part finder tools, and a customer base of enthusiast owners. Closest direct analog to Design911 in terms of brand-specialist focus, content-led marketing, and DTC e-commerce model.
- Stoddard (Stoddard NCS): Long-established US Porsche parts specialist and restoration house, selling new, used, and rebuilt parts across classic and modern Porsche models. Comparable as a marque-specialist with deep inventory and a hybrid retail/service model.
- Suncoast Porsche Parts: US distributor of genuine and aftermarket Porsche parts with strong catalog depth and a B2C e-commerce presence. Closely comparable in catalog breadth and enthusiast-targeted DTC motion.
- FCP Euro: US/European online specialist for European car parts (BMW, Audi, Mercedes, VW, Volvo, Porsche) with a strong DTC e-commerce platform and lifetime replacement program. Comparable business model in marque-focused premium aftermarket parts, though broader across European brands.
- Turner Motorsport: US BMW specialist offering parts, performance upgrades, and racing services. Comparable in operating a single-marque specialist parts business with both retail and trade channels and motorsport heritage.
- Bimmerworld: BMW performance parts specialist with deep catalog, brand-specific expertise, and dual consumer/trade motions. Operationally analogous to Design911 but focused on BMW.
- Moss Motors: Long-running US/UK specialist in classic British and European sports car parts (MG, Triumph, Mini, plus Porsche-adjacent). Comparable in operating a niche classic-car parts catalog with strong enthusiast community.
Broad incumbents
- Porsche Classic: Porsche AG's own classic parts and restoration division, supplying genuine and reproduction parts for older Porsche models. As the OEM-owned incumbent, it competes directly with Design911 on classic car parts and represents the most strategically threatening peer.
- RockAuto: Large US online catalog of aftermarket auto parts across all makes and models. Comparable as a multi-brand parts e-commerce platform competing on price and SKU breadth, though without marque-specialist depth.
- Euro Car Parts: UK-based large distributor of European car parts serving trade and retail. Provides geographic and channel overlap as a UK-headquartered European parts distributor, though not Porsche-specialist.
