Hi Brian, the car looks great, except for the tires and wheels.
Personally, if I built another Cobra, I'd make it a lot different. One, the engine would be a small block with twin turbos, still with a 6 speed for drag and road racing. A round frame, not rectangle. A quick change center section to make gear changing quick & simple IRS system.
Two roll bars with links going down to the frame. Narrow the front and rear frame and suspension to house much wider wheels and tires. Much larger brake rotors and calipers, 6 front and back.
Lower the front & rear in the weeds with a valve to raise and lower like air bags, the car. But electric jacks like CART and F-! use in the pits and my shop.
etc,.etc.
