Ma7da Championship

Introduced in 2019, the Yokohama Ma7da Championship is an offshoot of the eternally popular Locost Championship for kit cars designed to the original Ron Champion ‘Build Your Own Sports Car’ book dimensions. Ma7da offers the same ultra-close slipstreaming race action, but with increased power for those drivers looking for a step up in performance.

Granted Motorsport UK Championship status for the 2021 season onwards, Ma7da accommodates drivers having stepped up from Locost, or newcomers looking for a formula that offers great racing with a tightly-controlled Seven-esque car platform, yet with the value and unbeatable entry costs offered as a 750 Motor Club package.


Utilising a high-quality package from KitSpares, a typical Locost can be ugraded by a DiY racer to use a reliable and affordable 1.8-litre VVT Mazda MX-5 'Mk2.5' engine and gearbox for little more than £4000 including all parts and a secondhand engine and gearbox. 

‘Control’ Package Parts

The Ma7da Championship will typically run at six events per season, with a mixture of double or triple-header events to maximise value for money.


As an approximate guide; 750 Motor Club membership is £25 for 12 months, season registration is £135, and race entry fees typically range from £250 - £350 depending on the circuit (for a double-header race event).
