Kind of cool from figures I've seen in the past of forum members claiming their 67/68 FE Mustang's weighing in under 3,300. Supposedly the GT350 "R" model gets the carbon fiber wheels & rotors.....and delete of rear seat, A/C, audio sys, spare tire, aux gauges and floor mats.
Quote: "Ford has at long last revealed a key Mustang Shelby GT350 specification: the lightweight, hard-core R model’s weight. The automaker’s just-revealed 3650-pound weight claim for its latest super-Mustang is promising, especially paired with the coupe’s 526-hp special flat-plane-crankshaft 5.2-liter V-8."
