Team Sellars Racing (aka TSR Engineering) run by Stuart Sellars, are big players in the world of 750 Motor Club Locost and Sports Specials championships and for clubman racers, they offer a full package from racecar preparation to arrive and drive; from engine tuning to custom-built dampers.

They’ve also recently launched their new TSR Lotus Seven-inspired model for the new for 2020 Ma7da Series, which formerly ran as part of the Locost Championship under the control of the good folk at the 750 Motor Club.

The TSR is built around the Ma7da regulations calling for a Mazda MX-5 Mk2½ model, which has a feisty little 140bhp 1.8-litre VVT four-cylinder engine. This is the relatively un-loved MX-5 model, falling way behind the Mk1 and Mk3 in the popularity stakes, meaning that donors can be bought very inexpensively.

The TSR pictured here was on the 750 Motor Club stand at the recent Race Retro 2020 show and belongs to 21-year old, Oliver Sighe, who may be tender in years but is a relative veteran in motorsport terms.

Oliver won Class M of the MAX5 championship in 2018 in his Mk1 MX-5, before graduating to Class B in a similarly liveried (sponsorship opportunities exist for 2020!) Mk3 model, where he was a race winner.

He’s very excited to be joining the Ma7da Series this season and thus far is one of 20 entrants, a number which is sure to grow before the season kicks off for Ma7da at Cadwell Park on May 3.

Young Oliver has a website which can be found at

If you fancy having a go at the Ma7da Series, not only will you be made very welcome but as far as motorsport goes it’s a very competitive and dare I say, affordable series. You have several choices as far as a donor car goes. You can go and buy an old Locost and buy a specific kit of conversion parts from TSR (do it yourself or they’ll do the work for you) and source an Mk2½ MX-5 for not much money.

Do that and you’ll see that there’s plenty of life still left in an old once Ford-based Locost, especially with a 40bhp power hike over the Locost Championship cars. Alternatively, you can contact Stuart and Steve at Boston-based TSR Engineering (by the way that’s ‘Boston’ in Lincolnshire rather than New England in the USA!) and they’ll either sell you a complete kit or supply you with a brand new TSR…

Oh, and good luck to the incredibly affable and enthusiastic Oliver in 2020. We’ll be keeping an eye on how he gets on …
