depends on whether the car is lowered or not. if it is, then it depends on just exactly how low it is. also whether you are going to have an aftermarket spoiler on the front or the OEM one. The OEM is a lot more forgiving than some of the others. I have a rather steep driveway also and have to come up it at an angle. I absolutely can't lower my car or put CF front spoiler on if I wanted to due to the certainty of it getting damaged or not even being able to drive up it.
