Believed to have been used as a development / spare car and not raced during 1993/94, although this has yet to be confirmed.

In 1995, this car together with RT05 went to Australia, where it was driven by Brad Jones in the Australian Super Touring Championship, as well as the non-championship Grand Prix support and Gold Coast events.

At the end of the year, one of the two cars were sold to Czech team Stuard, although it is not if this was RT05 or RT06
