Thanks Steve, I was unsure how much detail to include, technical detail is not riveting to everyone.

Yes, the wheels were centre locks to their own design. Pattern making and casting alloy for race cars (and other applications) was one of Lyncar's specialties.

The front wing, and a rear wing (but not the one in the photo which is alloy) were delta shaped and female moulded using a technique I developed. I laid up a wafer thin fibreglass skin in the mould then poured 2 pot foam into the cavity which made an accurate, rigid and incredibly light wing section. The front wing was adjustable for angle while the 'glass rear one was a two piece with both sections adjustable.
