Well height alone isn't the factor to consider. Where was it getting close to scraping? Because if it's the bumper, than the longer the distance of bumper from wheel will require higher clearance. Say, if your BMW has 3ft from wheel to front of car, and with 6.25" clearance being enough, if the model S has less clearance, but only has say 2.5ft from wheel to the front of the car, it may still be just fine.
Same applies to if you need the clearance in the middle of the car. If the distance between rear and front wheels is shorter than your BMW, the less clearance you'll need, and vice versa.
Here's an image I took when the person came over to test their M3 RWD Aero wheels. So it's the middle of the car that scrapes since the front wheels are dropping down to street level, the rear is still coming up the driveway ramp. (Also, I feel like I'm intruding on the real post here... not sure the etiquette). I assume this thumbnail will link to the full image.
