On the 2007 BMW E90, after I set ride heights in the garage to 11cm on all four sides (with 0 degree camber & toe and equal tire pressures), while stationary in the pits motec i2 pro shows 11.8 cm ride heights on all sides. That's acceptable.. But, when I set them to 10cm in the front and 11cm in the rear, motec shows 10.7 on all sides. 11cm in the front and 10cm in the rear gives 12.0 cm on all four sides in motec. Ride heights are adjustable from 8cm to 13cm with 0.1cm increments for this car, and even though I didn't expect 0.1cm accuracy, I thought that I could get reasonably close to 10cm in the front and 11cm in the rear. What's the deal? This sort of thing happens on the 2007 Chevy Lacetti as well.
