Presumably an adjustable beam is not allowed but obviously springs and dampers are. Are you allowed to fit anything that was fitted to a production line Cosworth i.e you've got the 3-door hubs. Can you change ARB's, adjust caster/camber etc?
You're right - can't change the beam as the "pick-up points" cannot be changed so arm mounts, beam mounts must be original. I have braced the centre of the beam to stop it flexing and connected it to the roll cage in the floor. Three door hubs are OK, coilovers are OK, compression struts are allowed but not adjustable TCAs, bushes can be standard or poly. I have adjustable top mounts. ARBs are free I think but I use standard Sapph front and back.
At the moment it turns in well but has a bit too much power on oversteer so need to work on the back to try to iron this out - may go lower and softer dampers next time. Also I should lower the front a little bit more.
