The Alpine doesn't have the Ackerman problem because its steering
mechanism operates from behind the front axle, and it's much easier to
set up ackerman correction from that side. When the steering arms are in
front of the axle, the tie rod balljoints have to be located further
outboard than the steering axis in order to get Ackerman correction. The
problem with the Tiger is that, at least with the stock discs and
wheels, you can't get the tie rod balljoint that far out because it
would hit the brake disc. The issue is compounded by having the rack
located far ahead of the tie rod balljoints.
To Bob and Mike Hokanson: Does the front crossmember that you built
locate the rack under the oil pan, and do you then end up using one of
the late model 5.0 (rear sump) oil pans?
