By 1964 Bernard Unett made XRW 302 (opposite) the most successful alpine in club events. Unett decided to enter the Freddie Dixon challenge Trophy, which was then considered to be the the biggest prize in Club racing. Awarded on a points system, Unetts four wins, five seconds and two third and one forth place were enough to win him the trophy. Rootes collegues Peter Coleman and Fred Evans helped Unett develop the car, using special squared topped cam follower lobes to increase power, making it incredibly fast. so fast that it always caused a few comments from motoring journalists as to what was under the bonnet.

In 1965 Unett was racing a Sunbeam Tiger (opposite) gien to him by the new competitions manager and ex - Le Mans driver Marcus Chambers, (registration number ADU 180B). It was one of the two ill prepared Tigers that had embarrassingly short outings at the previous years Le Mans 24 Hour race, being hurriedly put together and over weight with poor breaks and engines. After being modified by unett, he was easily beating the competition and getting glowing press reports.
