If speedway built Mildenhall and greyhounds gave it its name, it is stock car and banger racing that fills much of its modern calendar. The shale oval is one of the regular East Anglian homes of British short-oval motorsport, run by a promoter whose name is woven through the whole sport.
Spedeworth: the promoter
The stock car racing at Mildenhall is promoted by Spedeworth International Ltd (Spedeworth Motorsports), described as one of the leading short-oval racing promoters in Europe and active since the 1960s. Spedeworth is led by Deane Wood, who bought the company in 2004 and went on to buy Mildenhall Stadium itself in 2016, from the previous owner, RDC Promotions. Spedeworth runs a network of oval venues — Mildenhall alongside tracks such as Foxhall Stadium in Ipswich — and it is the stadium's landlord as well as its stock car operator.
What short-oval racing is
Short-oval racing is raced anti-clockwise around a compact oval, and in most classes deliberate contact is not just tolerated but central — "the contact is the game". The categories at Mildenhall span the full range, from precision-built racing machines to gloriously expendable scrap:
- BriSCA F2 Stock Cars — purpose-built, roll-caged single-seaters on a 2-litre Ford engine; a mainstay class and full contact.
- BriSCA F1 Stock Cars — the heavyweight tier of the sport, racing at Mildenhall since 1987.
- National Saloon Stock Cars — saloon-bodied contact racers with a strong following across the UK and the Netherlands.
- National Bangers and other banger classes — production road cars stripped of glass, fitted with roll cages and reinforced doors, then raced with heavy contact.
- V8 Hotstox, Reliant Robins, Junior Micra Stock Cars and Historic Stock Cars — a rotating cast of supporting and novelty formulas.
Not every class is a contact class: Hot Rods, for example, are decided purely on driving and lap speed. But it is the contact racing — and the spectacle of the bangers in particular — that draws the biggest crowds.
The shale oval
Stock cars and bangers share the stadium's tight shale oval of roughly 260 metres, ringed by Armco and steel-plated fencing rebuilt after the 2024 fire. It is the same circuit the Fen Tigers race on, and a separate track from the 325-metre sand circuit used by the greyhounds. The short layout keeps the action tight and the contact constant.
World finals at West Row
Mildenhall is a championship venue, not just a club track. The Spedeworth calendar has scheduled a string of finals at West Row, including the BriSCA F2 World Championship Semi-Finals, the Ladies Bangers World Championship, the Reliant Robins World Championship and the National Bangers 2-litre ORCi World Championship. When the stadium reopened on 22 March 2025 after the fire, it did so in fitting style — with the National Bangers Unlimited Supreme Championship, a meeting of more than a hundred cars.
A wider scene
The racing at Mildenhall plugs into a European short-oval network. The Dutch F2 Stockcar Supercup, for instance, runs the same style of F2 cars on shale in the Netherlands — the continental cousin of the BriSCA F2 racing seen at West Row, and a reminder that this is a sport with deep roots on both sides of the North Sea.
