Lowering the center of gravity by 1" must be corrected for the tread width of suspension so the 5% gets reduced by 1/3rd so at best the roll transfer weight on a tire is improved by much less than 2% [1.7%].

TireRack has some excellant track/slalom/skipad test on lowering and spring/sway/shock changes on BMW and show how little you get for major changes.

Tires create 90-95% of possible handling and suspension adds the rest.

(These guys do alignment by hand, they do the suspension on the RSR drift cars, so I do trust that they actually do the alignment! I am highly suspicious that some places do not ) The rear camber was off pretty badly, and could not be put back into spec w/ stock hardware. By the time I was able to get a rear camber/toe kit installed and another alignment done, the damage was pretty much completed. Rear tires were showing cord in the inside after about 7000 miles. I just got new rear tires, and another alignment. Now I find out my shocks are blown! Haha. My luck just never runs out. So I will be getting new shocks, probably D-Specs, and paying for another alignment. I strongly suggest being cautious even when going with a mild drop, as this scenario could possibly happen to anyone.
