Haz,
I have an recent aero sketch you could use as some reference. It also uses a Stratos glass & teardrop driver compartment. The base donor was Caparo/Hulme-like open front wheel concept. I've enclosed the front wishbones & rear wheels. The side intakes are maybe too big for good aero-numbers. You could delete the rear wing & add proper wheel covers. The short-tail proportion may work for your purposes. You could use Toyota Celica lights for your front clip.
