Well the quote made me gulp a bit but we have decided to really go for it on the car, I will add pics of the spec as it builds up but as a hint we are taking out the bulkhead completely and cutting out the old floor and tunnel right to the place where the back seats would have been, then the boot will be cut for a new fuel cell and the big WRC arches / Turrets and cradle mounts. The bulkhead will be moved back a bit to allow more space in the bay and for the engine to move back a bit.
