Anyone have the approach/departure angles of the F87? I was able to find a ground clearance spec listed here of 4.8 inches, but did not see approach or departure angles. I am moving to a Cayman GTS that will have 4.4 inches of ground clearance and a 9.7 - 14.3 degree approach/departure angle.

I found I needed to be very cautious about the front fascia / spoiler on my M2 in certain places, and I am just wondering whether the Porsche will be any better or worse. Unfortunately, I can't seem to find the approach angles for the F87. Appreciate if anyone has them handy.

The approach angle isn't all that bad on the M2 given it's relatively short front overhang (assuming no additional lip). It's probably more forgiving than even most non-sporty front wheel drive cars which have longer overhangs. Porsches generally seems to have longer front overhangs, and combined with the lower ground clearance, I imagine you'll have to be more cautious with the Porsche. I know you're talking Cayman, but there is a reason Porsche offers a front axle lift on its 911s.

While I have no info on "approach angles" for the F87 (Frankly, I'm not sure what they are) I "assume" it means the angle that provides the most clearance when approaching a rise?

If so, the clearances at the front between the two cars are likely not comparable, as the Porsche has a greater front overhang than the BMW - which means it'll touch down sooner as it will arrive at the "rise" first. Also, how does one determine the angle of approach from the driver's seat?

The only saving grace, possibly, is that the front lip of the Cayman seems to have a taper or angle to it as it approaches the front wheels, whereas the BMW's did not.

My BMW couldn't handle my in-laws' driveway and even the dip in the road at the intersection of their street (concrete rain "gutter") was problematic to the point I typically had to go around it entirely. Certain parking lots were also no-goes. If the Porsche is even worse I am going to have to be very careful.

Porsche offers front axle lift. At least on 911s.

Bmw has short overhangs which aids clearance but also makes the front end more vertical like a door. Bad for aero.

As for approach just try to hit the incline with the tire first. Like getting a first down but crossing the line with your front tire rather than bumper.
