Limiting front suspension travel (EXT) can cause problems with Caltrac cars. Calvert asks for a minimum of 5" I believe, which may necessitate the cutting down of bump stops. Basically we're asking the suspension to move in a range they were never designed for

No issue cutting the bump stop. Travel and shock dampening are two seperate tuning windows. You can still use tight shock settings with a lot of travel. A car that is real nose heavy and or a very long wheelbase may like a lot of travel. For what it's worth. On my 64 Belvedere I tested removing the bump stops. It was only worth 1/2" increase in travel at the wheel.

The red Cuda with the camber change: lengthen the upper arms (Jack Arnew was the guy on that back in the day) and/or adding bump stop height.
He did the front end on my Duster back in its SS days in the '70s. Basically widened them to move the spindle to a more vertical orientation.
Side effect is I can get over 7 degrees + caster. Car goes straight as a string & no issues when the tires come back down to earth.

Mine are as well. I actually have some low profile poly ones in there but they just barely touch the arm at full droop, I should probably just take them out and save the lbs.

The AMX I race used to have the front tire wobble, but since I rebuilt the front end, installed heim joints on the strut rods, and did a alignment is has been good.

Also remember Caster is relative to frame angle. A 2 degree rake with 3 degrees of caster will be 5 degrees when the car is at speed and level. Mine runs 2 1/2 degree of caster with 2 degrees of rake. Drives perfect at 150

Make sure you have no worm out, bent or broken pieces up front, I doubt you will find anything but check for sure. But looks like typical bumpsteer to me. Lots of ways to fix it..

Did a quick search and this is a decent explanation of what it is and does. It can easily be measured on your car and then can be addressed a few ways, may not be able to TOTALLY get it out but can be made better.
