[QUOTE="ac427cobra, post: 12219908, member: 6247"] There is a clear and concise reason, which nobody can argue, that Cobras cost more than Mustang GTs when they were new. This is the exact same reason that Cobras command higher resale values than Mustang GTs when they are used. They originally came with better engines, better transmissions, better brakes AND, wait for it ................................................................ better suspensions that include the infamous IRS!!! :-D So when you convert your Cobra suspension to a Mustang GT SRA, this makes the car less Cobra and more Mustang GT. It also speaks volumes for resale value that somebody most likely beat the crap out of the car drag racing it. This decreases value, plain and simple. The team of SVT engineers, employed by Ford Motor Company, who by the way are engineering graduates that are specialists in vehicle suspension systems and vehicle dynamics. (they are not weekend warriors like most of us) These guys actually make a living developing cars and drive the top secret camouflaged prototype cars on Ford's proving grounds. They also go to tracks in the Michigan area like Waterford Hills, Grattan Raceway, GingerMan Raceway and Mid-Ohio.
