FYI, Stealths and 3000GT's are not DSM's. And really they aren't as heavy as people make them out to be. Most of the fully loaded VR4's were 3700 or less. The 95-96 Stealth RT Turbo's were 3400-3500. Mustangs weigh more than that.
And on DSM's they are not heavy at all. My 93 AWD TSI I had was only 3100 lbs.
