Thats really not a fair comparison. Sure they make similar power, but the Mustang is a pony car. This means it was made for drag racing and stop light warriors.
The Corvette is a sports car and the Z06 is close to be considered a Supercar, at least that what R&T says. Thats a totally different class.
In addition, Ford made a conscious decision to go with a live rear axle due to the type of customer they routinely see. I would have loved if the car had IRS but research showed that many people were not interested in it.
Anyway, its a sweet car and I would love to get one, strip it down and run some 9’s.
