Under the old regs there used to be a base minimum weight of 1000kg including driver with an additional 20kg penalty for EFI and another 40 kgs for multi valve engines to try to give some parity to older cars, certainly not a performance advantage. They have decided with 4 weeks to round one that all cars must be minimum 1040kgs including driver, no reason given.

I think anyone who runs older race engines knows how hard ( and expensive) it is to get decent useable power, but as I built my car to be period correct and to sched K there are plenty of other places to play. My concern is only with the safety issue of the potential of 50 odd kgs of ballast flying around and wondered if indeed there was a precedent or accepted way of adding ballast short of getting real fat. Maybe run a swinger like a sidecar unit?
