750 Formula Car - SDAR/24


The 750 Formula is the oldest continually running racing formula in the world. Names such as Arthur Mallock, Colin Chapman, Eric Broadley, Mike Costin and Gordon Murray, to name a few started with the 750 Formula. The current regulations result in a variety of cars that have to use the same Fiat 1108cc ‘Fire’ engine with limitations on the modifications. This leads to close racing within a ‘slicks and wings’  format.


The car on sale is a unique creation by Dave Robson based on his many years racing cars to his own designs in 750 Formula. His cars have won races, claimed fastest laps and claimed two championships. This car is modelled in CAD and benefits from the use of laser cut components and 3D printed parts. It has a new chassis and engine and is ready for the 2024 season following a successful shake down at Donington. It is based on the SDAR/17 car that has been developed over a number of years and proved to be successful yielding 2nd and 3rd positions. The full list of features is given below but the key elements are its semi-monocoque chassis, carbon bodywork, 15 channel AIM logger, alloy cased Quaife dog box, .…. and much more

This is a race winning car in the right hands.
