I have run my C4 ZR-1 with both the early and late front suspension
geometries. The 88 and later zero scrup uses a longer lower control arm and
has more camber gain which I believe to be an advantage. Other's experience
to the contrary may be due to dialing in too much static negative camber
instead of using the camber gain. The change to zero scrub makes for less
kickback in the steering wheel when under full ABS in front which is
probably the reason the factory went to it in the first place.

Good summary, Adam. Wanted to add that major
revisions were made to the C4 chassis in '88; the rear
suspension geometry was reworked for a lower roll
center, and the front for "zero scrub radius" (in
practice, this was achieved by increasing king pin
inclination to something ugly like 15 degrees).
Which is faster in autox is probably an open question.
The new rear geometry produces less jacking and may
have greater cornering capability (on pre-'88s you can
watch the outside rear jack up in hard corners). I
have talked to SS folks who do not like the '88-up
front...they say the new geometry kills low-speed
turning response. In practice it does not seem to
have hurt Scotty White's car ('89?) :)
Has anyone ever tried _back_dating the front
suspension on a late C4?
