NSRA Supernationals 2026
The NSRA Supernationals is the largest hot rod and traditional US car gathering in the UK, organised by the National Street Rod Association on Old Warden Park aerodrome in Bedfordshire. Held annually on the third August weekend, the event draws 1,500+ rods from across the British Isles and continental Europe, with a strong emphasis on pre-1949 traditional builds and 1950s customs.

Exhibitor tips
NSRA judging is heritage-focused: period-correct mods score higher than modern restomods. Traditional flathead V8s, 32-roadsters and Model A coupes dominate the Pre-1949 Top 10. The "Picnic Plot" is the social hub — pre-1965 vehicles can park there alongside their owners' picnic blankets. Excellent place for parts trading.
Models that win at Supernationals
Winning regulars: 1932 Ford Highboy roadster (flathead-powered), 1934 Ford 3-window coupe with full chopped top, 1949 Mercury custom (lead sled style), and 1957 Chevrolet Nomad in resto-mod trim. We've helped import several 1932-1934 Ford rolling chassis for UK builds — see our gallery.
