Nothing is wrong with leaf springs. Mike Maier is a well known mustang guy for the racing scene that makes custom fabricated parts for classic mustangs. He has several race cars that he's built using leaf springs that easily keep up with and even beat cars with full coilovers. Plus, to anyone who has ever tried putting coilovers on a classic mustang, they know that there is not a ton of room around the rear axle to do so. This is actually why Mike Maier makes a kit of his own design which coverts the rear suspension to a pushrod coilover setup moving the coils into the trunk. That kit is geared specifically for classic mustangs that are sitting much lower than normal. In common stock or lowered applications, leaf springs work just fine.
I guess you're unaware of how legendary the Halibrand wheels are to the Shelby name when Cobra 427s were being produced back in the 1960s. These replicas are keeping in tune with that vintage 60s look but with modern rubber due to being available in 17 and 18 inch versions nowadays.
You think they would of used a carbon fiber drive shaft and the real question is can it beat the 2018 mustang and it's still a Ford fixed or repaired daily already have problems trying to get it to start
