I’m ok on the front... it’s the middle I was worried about.
Here’s my math... the AMG wheelbase is 109 inches... when the back wheels hit a 36” ramp. 36/109=33% Only 33% of the 5 inch platform will be lifting the back third of the bottom as it approaches the ramp. So 1.65 inches plus my 4 inch clearance (no driver weight) means that section of the car will be 5.65 inches above the ground when the back wheels strike the ramp.
With a 48 inch ramp, 48/109=44% so 2.2 inches on the 4 inch normal clearance provides 6.2 inches from Floor height to bottom of car. Unfortunately my driveway sits 1-2” below my garage floor and the ramps will extend out there. Looks like I should relayer the driveway now.
For entertainment value, “let’s get a lift” morphed into; let’s replace the three garage doors too, might as well get all three high lift with new side mount openers, might as well get an epoxy floor before the lift goes in, now let’s replace the driveway too... 🤦‍♂️
