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, 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.

Upgrade

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 £3000 including all parts and a secondhand engine and gearbox.
