RT with Track Pack ride height is same as SRT. Driveway is not a problem. Curb or parking stop when you park perpendicular might sometime hit the spolier. You will learn when you should stop. Many owners lower their cars even further than the stock SRT. I myself will lower mine about an inch once Eibach comes out with thier kit for 2012 and later cars equipped with adaptive suspension. That will be kind of the G machine look but not consider slamp down like many imports.
