Do you mean the indoor series that were run between the DMS & Silverstone clubs? Held for a while at Lings Forum (Northampton) for the Silverstone events & at a Leisure Centre in Watford (different to the still current location) for the DMS meetings - both with Ray Paice at race control
I managed to get some good results with my Mardave Cobra at these events - that car liked flat carpet tracks!
