I have an 04' and I have a gutter out in front of my house and the car has no problem forward or backward straight on. And my driveway is angled up slightly, so I would imagine you could make it. I think I have read that the SRT is 5.1" off the ground.
I'm pretty sure that if my Honda S2000 scrapes, that the Viper will!
If it has a regular subdivision curb like mine does the best way to get in and out with no scraping sound is to back up the driveway. I tried pulling in at a 45 degree angle but backing in was the solution for me.
I don't know why some owners lower their Viper even more. These things are low enough already.
