Are we allowed to do any thing to correct bump steer on an ITB Mustang?

Your best action is to not lower the car so much that bumpsteer is an issue.

Bingo. That and follow the old adage "Any suspension will work as long as you don't let it".
Just asking a question here: Couldn't you consider the steering system on a rack-n-pinion steering system part of the suspension? The tie rod is a link in the suspension and it's connected to the rack which is connected to the K member with bushings. And since suspension bushings are free in IT then couldn't you take it to the point where you can use offset bushing to try to correct bump steer? Dicuss.
I owned and raced a Fox Mustang and know the issues of bump steer. I didn't race it in IT so I was able to correct it using the more common heim joints in lew of tie rod ends method rather then offset rack bushings.

I suspect that is a bit of a tortured interpretation. The GCR defines suspension bushing as:
Suspension Bushing – A hollow cylindrical mounting component which
acts as a bearing, allowing constrained motion, between a suspension
component and attachment point.
The IT bushing language is:
Bushing material, including that used to mount a suspension
subframe to the chassis, is unrestricted. This includes
the use of spherical bearings, so long as no suspension
component is modified to facilitate their installation. Retention
of spherical bearings by use of tack welds is allowed,
as long as the welds serve no other purpose.
And that language is under "Suspension Mounting Points". Steering is not specifically mentioned or called out, but, steering as defined in the GCR is a bit weak and doesn't specifically cite the rack.
There was something going around about that thought process a few months ago. basically, as Ron said, it's a tortured interpretation and I would expect some feedback about it.

I don't know how you came to the conclusion that the tie rod is a link in the suspension, but I disagree. You can leave the tie rod laying on the shop floor and still have fully functional "suspension", as defined in the GCR technical glossary - "A mechanical system of components controlling vertical motion and connecting the axle housing and wheels to the chassis of a car."
IMO, the tie rod does not meet the first of two requirements in that definition.
yes there is a kit out there to correct the issue of bump steering in a lowered mustang. it looks like a spacer between the tie rod end and the steering knuckle.
