Unacheivable Goals

Having read in Allan Staniforth’s book that the bottom arm should incline 10° and the top decline 20-30°, I decided to plot this out.

The drawing below shows, that for a road car, these goals would be totally unacheivable.

The Instantaneous Roll Centre would fall roughly inline with the chassis on the same side. The change in camber with any suspension movement would be incredible.

For these design goals to work, virtually no ground clearance, huge wheels and massive uprights would be needed. In other words a Formula One racing car.
