SR3 Cup


The Radical Caribbean Cup is the region’s premier one make racing category in which all competitors race in 1500cc SR3's.

The series is administered by Bushy Park Circuit Inc (BPCI), which was appointed sole distributor for Radical Sportscars in the Caribbean at the end of 2017. The Championship, though established at Bushy Park Barbados, visits circuits in Trinidad and Guyana also, with a truly multinational roster of drivers, many of whom dovetail their Caribbean Cup campaigns with outings in Radicals at other international series. BPCI liaises with the Organising Clubs in each of the host countries to ensure a level playing field for all competitors and is responsible for co-ordinating the shipping of cars around the region, along with the technical support team and spares package.

The Radical Caribbean SR3 Cup first ran in 2018, a four-round series contested at head-lining race meetings in Barbados, Guyana and Trinidad & Tobago. The launch of the regional competition followed three successful seasons of the Barbados-based Suzuki Challenge Series (SCS), which also hosted the off-season Radical Carnival for three years, attracting drivers from Europe and the United States.
