Porsche 911 ST
The 911 ST is the early lightweight's holy grail: the 1970-72 works-and-customer competition 911s — 2.3 to 2.5 litres, Le Mans and Targa class wins — whose loose-run rarity makes authentication the entire market.
History
Porsche's ST designation (1970-72, informally applied to the competition-lightweight 911s the factory and customers campaigned) armed the early era's GT racing: the 2.2-then-2.3-through-2.5-litre evolution of the racing flat-six, lightweight body construction (thin-gauge panels, the era's aluminium-and-glass-fibre economies) and the campaigns the type's ledger records — Le Mans class wins, Targa Florio class honours, the Tour de France's road-race chapters, and the customer GT racing worldwide that made the ST the 911 competition lineage's founding lightweight before the Carrera RSL/RSR institutionalised the formula.
The loose-run reality defines the market: STs were built in configurations rather than a numbered series (works cars, customer competition orders, the era's specification fluidity), making the population's scholarship — which cars carry genuine ST specification and history — the authentication battleground the type's values demand.
The collection present prices the founding status: genuine STs at early-lightweight summit stakes, the recreation economy (ST-specification builds on period bases, honestly declared in the market's better half) serving the driving demand, and blue-riband historic eligibility rewarding the authenticated.
Palmarès
Le Mans and Targa Florio class wins, Tour de France road-race honours and the worldwide customer GT campaigns of 1970-72 — the founding lightweight's ledger before the RSR institution.
What to check before you buy
Authentication is the entire market: the ST's loose-run reality (configurations, not a numbered series) makes per-car scholarship decisive — period competition documentation, factory-records correlation and the marque historians' opinions separating genuine STs from period lookalikes and modern recreations; the value tiers are universes, and the declaration's honesty is the trade's test. Engine-specification correctness (the 2.3-2.5 evolution's details), lightweight-material originality, and campaign provenance structure the authenticated tier. Recreations serve driving honestly at declared stakes; the summit belongs to the documented.
Did you know
- ST was never a catalogue model: the designation's informality being exactly why authentication became the market's whole discipline.
- The founding lightweight preceded the institution — the RSR's formula existing because the ST's configurations proved it.
- Specification fluidity was the era's norm: works and customer STs built to purpose, not brochure — the scholarship's eternal employment.
