step cont arms or drop spindles....

[vin63]

Yes, a dropped spindle has the engineering done for you. Here's a link to what I was talking about (CPP drop spindle and stock spindle photo side by side). http://www.classicperform.com/Store/...ruck/CP4S1.htm

If you were to move the stock spindle up 2 inches via a stepped lower control arm, the steering arm location would also move up 2 inches. This means the angle of the tie rod attachment to the steering arm would would increase up toward the spindle - this would significantly change the angle of the tie end rod in relation to the lower control arm angle. Even slight changes in steering geometry can have severe affects on handling and bump steer conditions.
