The sporting regulations changed to FIA sanctioned Group A specification, and three different classes competed for honours.
TWR expanded their team and ran a trio of Rover Vitesses for
Pete Lovett,
Jeff Allam and
Steve Soper.
Austin Rover would also back
Roger Dowson Engineering who ran Turbo Metros in Class B whilst Ford supported a semi-works
Ford Escort outfit in Class C.
GM/
Opel entered a single Opel Monza for
Tony Lanfranchi. Reigning champion
Win Percy would once again drive for
Toyota, this time at the wheel of a Supra. Meanwhile,
Frank Sytner raced for the works
BMW team. TWR dominated the season, winning all 11 races. The drivers had the races pretty much their own way until Sytner, who had fallen out with Walkinshaw and left TWR the previous season, protested the legality of the Rover cars to the governing body. In response, Walkinshaw protested Sytner's BMW which led to extended legal wrangling which would drag on until long after the season was over. Soper beat his more experienced team mates and won the outright championship, while
Andy Rouse who had taken over the
Alfa Romeo GTV6 run by
Pete Hall won Class B after a season long dice with the Metros. In Class C,
Alan Minshaw took the class honours in his Volkswagen Golf, seeing off the Ford challenge. However, six months after the championship was over, Sytner's protest was heard by a Tribunal of Enquiry, chaired by veteran legal counsel Lord
Hartley Shawcross. The result was the RAC disqualified the Rover team entirely over bodywork irregularities and engine installation issues, handing the title to Rouse. In response, Austin Rover withdrew from the BSCC immediately as a works outfit to concentrate on competing in Europe, and would not return until 2001 under the guise of
MG Rover. ==Teams and drivers==
