I, and I understand from searching the forum, many, have struggled to get a clear description of what is standard ride height. I still don't have a perfect answer but I googled for schematic profiles or elevations of bay windows and found a few images from manuals etc. that give a good reference. Essentially, it seems standard had: - floor height of about 500mm above ground - rear trunk / boot / floor height of about 975mm above ground Also, a good go by seems to also be that the rear wheel wheel arch / guard aligns with about the middle of the side of the wall of the tyre. From the above, I was able to determine my car is about 50mm below stock. I've attached the images for info to help others wondering the same question of what is 'stock'.
