The JRM RR23 is a track-focused, road-legal supercar produced by JRM Group in commemoration of its World Championship win with the Nissan GT-R Nismo GT1. Only twenty-three units of this special edition will be produced, and it inherits over ten years’ worth of motorsport DNA from operating at the highest level of GT3 racing. The vehicle features highly engineered components and systems designed and built entirely in house by JRM in Northamptonshire and showcases British engineering in simulation and analysis, lightweighting, precision machining and 3d metal additive manufacture.
