Ma7da Series

Introduced in 2019, the Yokohama Ma7da Series 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.
For the 2020 season the Ma7da Series will run on its own standalone grids to accommodate swelling numbers of drivers looking either to move from Locost, or 750MC newcomers looking for a formula that offers great racing with a tightly-controlled Seven-esque car platform yet the value 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 Mazda MX-5 engine and gearbox for as little as £2000 + VAT including all parts and a secondhand engine and gearbox. 

‘Control’ Package Parts

To be released shortly, the Ma7da Series is expected to run at six events in the 2020 season, all 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 £90, and race entry fees typically range from £250 - £350 depending on the circuit (for a double-header race event).
