1969 Lotus Super Seven 'Series 3' Spec Twin Cam Race Car

Offered here at Race Retro 2026 is this very well-presented example of the Series 3 Lotus Super Seven Twin Cam, uprated for competition and, in the right hands, a proven and highly competitive race car. It benefits from a fully uprated and strengthened chassis fitted with an FIA-specification roll bar, powder-coated and re-panelled by renowned specialists Arch Motors. The car is dated June 1969 and recorded as a Series 3 on the V5 but it originally began life as a Series 2 competition car in 1966 and was subsequently subject to a significant, professional restoration and uprating by Arch Motors. As part of this work, the car was rebuilt to full Series 3 specification, incorporating the correct Series 3 components including engine, gearbox, rear axle, instrumentation and other Series 3 and specialist race parts. Importantly, it retains its original 1966 Series 2 chassis plate, numbered SB2153. The cockpit is correctly set up for competition with a GRP race seat, in-date Willans six-point harness, and period-style instrumentation including a Smiths chronometric tachometer and Rollcentre lap timer. Handling is carefully sorted with relatively recent Nitron race suspension, rose-jointed where appropriate and fitted with uprated bushes.

Power comes from a full-race, steel 1.6-litre Lotus Twin Cam engine producing around 175bhp, originally built by respected Lotus engine builder Craig Beck. More recently the engine has been refreshed by Stuart Rolt and has seen just 25 minutes of running since. Breathing through a competition stainless steel exhaust, it is supported by a Varley racing battery and cooled via an oil cooler and upgraded cooling system with an electric fan. Fuel is supplied from a lightweight aluminium tank by a Facet Red Top electronic fuel pump and Malpassi fuel pressure regulator. For safety, the car is equipped with a recently serviced SPA FireSense plumbed-in fire suppression system.

Drive is transmitted via a Ford 4-speed, three-rail ‘bullet’ gearbox fitted with Quaife close-ratio straight-cut gears and all iron casings, including the bellhousing, gearcase, remote gear change and tail housing, have been replaced with lightweight alloy components. A competition clutch is fitted and the car is currently running a limited-slip differential with 4.1 ratio, and comes with a spare standard 3.9 ratio. It sits on Superlite 6x13 alloy wheels shod with almost new Yokohama A048 semi-slick tyres, with just one 25-minute race session completed.

We are informed the Lotus has been extremely well maintained and, being road registered, it is accompanied by its V5C registration document along with a small spares package including items required to return the car to road use, such as a handbrake, horn and number plate lamp.

LKH has enjoyed a highly successful competition career across the UK and Europe, racing at circuits including Spa-Francorchamps, Zandvoort and Croix-en-Ternois with organisations such as the HSCC, CSCC, 750MC, and as part of the successful Chapmans Chariots Lotus Seven Birkett Team. It boasts numerous outright and class victories, most recently taking overall honours in the Colin Chapman Trophy and a class win in the 2025 Walter Hayes Allcomers race in November 2025.

There is no doubt this is a well-developed, proven and highly competitive Lotus Seven. Fresh, on the button and ready for its next chapter, it is offered at a realistic estimate and needs little more than fuel and talent to add further trophies to the cabinet.
