The racing RX-7 is the rotary's working résumé: IMSA's winningest model of its era, Spa 24 Hours victor in 1981, Group B rally oddity and today's drift/club favourite — three generations of competition breadth few platforms match.

## History

Mazda's first-generation RX-7 (SA/FB, 1978) went racing instantly and everywhere: IMSA's GTU class became personal property — over a hundred class wins and a record streak that made 'RX-7' and 'GTU' synonymous — while Tom Walkinshaw's touring campaign stunned Europe by winning the 1981 Spa 24 Hours outright. A Group B rally homologation added gravel eccentricity before the class died.

The FC generation extended IMSA success into GTO with tube-frame silhouettes; the FD (1992) split its competition life between Japanese GTs, one-make series and the tuner world — where its twin-turbo 13B made it time attack and drag royalty — before drifting adopted the chassis wholesale for balance no piston car quite replicates.

Today's market mirrors that breadth: genuine period IMSA/Group B cars are documented collectibles; FD drift and time-attack builds trade on build sheets; club racers run all three generations wherever rotaries are welcomed. The engine is the constant — cheap to rebuild by specialists who know it, ruinous with those who don't — and the reason RX-7 buying wisdom starts with the builder's name.

## Palmarès

Spa 24 Hours outright winner 1981 (TWR, Percy/Lammers-era crews); IMSA GTU championships and 100+ class wins 1980–1987 (the class record run); IMSA GTO titles with FC-based cars; British Touring class honours; JGTC campaigns and one-make RX-7 series in Japan — plus the modern drift/time-attack record the FD accumulated worldwide.

## What to check before you buy

Generation defines the market: period IMSA/TWR cars carry documented histories (verify via series records — tube-frame GTO cars especially), FB/FC club racers trade on preparation, FD builds on power-level honesty. Rotary diligence is non-negotiable: compression readings by rotary specialists (numbers piston logic misreads), rebuild provenance by recognized builders, cooling-system engineering on turbo FDs. Check shell rust (FB/FC) and chassis straightness on ex-drift FDs — assume walls were met and price the repair quality. The rotary community's concentrated expertise is the due-diligence network; use it before money moves.

## Did you know

- The 1981 Spa win made the RX-7 the only rotary car ever to win a major 24-hour race outright — TWR beat the factory-backed establishment with a Japanese coupé.
- IMSA GTU's RX-7 streak ran so long that competitors lobbied for displacement re-ratings — the rotary equivalency argument that never ended.
- Mazda homologated an RX-7 for Group B with the rotary's smoothness pitched as a gravel advantage — the class died before the theory got its full test.
