Well.. The 2013 mustang 5.0 weighs in at 3675 auto tranny. 2013 camaro SS is 3900 lbs. big difference there. No ones asking GM to produce a tin can camaro. But it's not rocket science to cut 300 lbs off of a car that can still withstand a bit more HP or is it?
Life is short, drive it like you stole it!
