If it's about the same as the other SRT models, it should be 5-6 inches before it contacts anything.
A normal driveway is fine, what gets most people is the parking stops. My SRT8 Charger had a couple
marks underneath, but were not visible unless you got on the ground, I haven't seen a Charger or
Magnum (SRT) yet that didn't have a couple of marks.
