Front disc brake conversion on Demon-Now alignment is way off. Needing help!
....It drives fine with the 1 degree and I really doubt the average street / strip car would notice a difference in 2 degrees of caster either way...
If the front end was setup with the FSM specs, the difference between the feel of the FSM specs and the Skosh is significant. Like you, the chassis on the 73 I tried this on would not give me all of the positive caster I wanted without offset bushings. On one side we could get +4º caster, the other side would only go to +2.5º, IIRC. I settled for +2.5º set for both sides and used the minimum "Max perf street" settings. I made too many changes (BBP DB, 15x7 rims, 205/60-15 tires) at once to be able to say how much of the change in alignment made. Cumulatively, the transformation was metamorphic. Steering turn-in was markedly sharpened, attributed to the alignment change.
72 FSM (Preferred):....Caster.....│Camber ....<all>....Toe-in │
Manual steering.............-.5º.....│Rt. +.50º .......... .125 " .│
Power steering.............+.75º....│Lt. +.25" ........... .125" .│
I figure the reason that the factory didn't go farther was the lack of general acceptance of radial tires in 1972. Radials are much more tolerant of negative camber than bias or even bias belted tires are in terms of tread wear.
