2 unrelated parts to this question: 1) What is the benefit of horizontally mounted inboard shocks as seen on some race and exotic cars? Apparently they use a lever connected to the wheel to actuate them. Why are they better than vertically mounted directly-actuated shocks? 2) I'm still not clear on the benefits of reducing unsprung weight vs. sprung weight. Why is this important? If you had the choice of removing 20lbs. of sprung weight or 10 lbs. of unsprung weight which would you go for?
