From my recollection....
All on road tyres : The Monroe became The Flintstone, and The Uniroyal.
Slicks - BARC/BRSCC Production Saloons which came later. Wasn't that the ESSO as the former championships didn't exist post 1989.
I seem to recall the BRDC ran a series too (when they did things other than rent Silverstone out) though it might have been co-run one with BARC? Was that the Monroe/Flintstone series?
