The Automobile Club de l’Ouest (ACO) have today announced that Japanese chassis builder Dome will take the fifth and final spot for LMP3 chassis supply.

Dome will join the four chassis constructors already homologated by the ACO; Ginetta, Onroak Automotive, Riley Technologies and Adess AG.

The ACO hopes that by limiting the chassis to five it will bring stability to the ELMS series as well as offering a viable and profitable economic model to the constructors, and enabling the entrants to take advantage of the price cap.

Dome, founded in 1978 in Kyoto, has supplied 18 chassis to Le Mans 24 Hours participants, and it has also taken part in all the major branches of the sport, GT 500, GT 300, FIA F4, etc. It is a leading constructor in Asia and the ACO hopes that a ‘local’ manufacturer will help boost participation in the Asian Le Mans Series.

The Spec Nissan/NISMO normally-aspirated 420 bhp V8 engine supplied and maintained by ORECA remains for all chassis and all will use the X-Trac gearbox and Magnetti Marelli electronics.

At present 7 LMP3s are entered for the European Le Mans Series, with the season finale taking place at Estoril in Portugal on Sunday 18 October, and three for the Asian Le Mans Series.
