Thread: Front coil-overs

I got my instruction by reading Carroll Smith's books and as I remember it all came together for me after Tune To Win. I had read many other author's offerings, but they stopped short of really explaining how to design the system. Smith explained how to play with paper dolls to scale (I didn't have the advantage of software as you do). I played with it, re-positioning everything until I had minimum scrub, 3 degrees of camber gain in 4 1/2 inches of bump and zero bump steer through 9 inches of travel. The camber gain was achieved with the angle of the upper control arm while the lower arm was flat. The lower the frame mount end of the upper control arm is, relative to the ball joint end, the more camber gain you will achieve.

By the way, I have seen ball joint extenders for sale that allow more camber gain by angling the upper arm.
