Mustang at Grand Am races
 

I got interested after they start winning the races. What kind of mustang at Grand Am races:

--- Does the rear axle is still solid-one-pice or is it independent from left to right?

--- What engine is there?: N/A V6 or V8, Turbo V6?

Thank you. And How good are the new mustangs if you want to modify it for the track? Compared towards BMWsm 350Z...
