1964 Mini Cooper 970 S

K-A2S4/550537roadUnited Kingdom

A 1964 BMC Mini Cooper 970S homologation special, one of only 963 built during its brief ten-month production run, constructed on 14 August 1964 and finished in Tartan Red with a black roof. Originally campaigned on circuits throughout Britain and abroad during the 1960s, it was subsequently stored for nearly three decades before a comprehensive mechanical and cosmetic restoration in the early 2000s. Registered with the Ex-Works and Competition Car Register, it retains its original matching-numbers engine and gearbox.

Maintenance & restoration

  1. 1971
    Maintenance

    Rather than being scrapped when values were very low, the car was placed into dry storage, where it remained for approximately 29 years.

  2. 2000
    Restoration

    Comprehensive mechanical and cosmetic restoration carried out over roughly three years. The original 970cc engine was bored out to 999cc with a new lightened and balanced crankshaft, Cooper S connecting rods, race pistons, a lightened flywheel, duplex timing gears, a hardened and balanced camshaft, and a five-port race cylinder head ported and polished with race valves. The gearbox was fitted with a new straight-cut gear set and bearings. Underbody and suspension components were bead-blasted, powder-coated or replaced, including new brake discs, reconditioned calipers, hubs, driveshafts and new Armstrong adjustable racing dampers. Interior fitted with period-style instrumentation, new carpets, roof lining, and a wood-rim steering wheel using as much new-old-stock material as possible.

    Completed by 2003; matching-numbers engine and gearbox retained throughout.

This car's public record is built from its auction and competition history. Register your ownership and privately add your own records to make it a verified Legacy Metrics passport — provenance that backs your car's value at sale and gives your insurer evidence to price against. Roy reviews and verifies every registration personally.

Each chassis record is compiled from public auction archives and links to its source material. Ownership, competition and maintenance entries are extracted from those catalogue listings by an LLM, which can make mistakes — please contact us with any corrections. The summary is Legacy Metrics’ own writing; we do not reproduce catalogue text.

“Full” and “partial” documentation labels indicate how well each entry is corroborated in the underlying sources, not an audit of the car’s physical paperwork. Names of recent or living owners are withheld for privacy.
