All very good answers.

Many lowered cars with rack and pinion steering experience bumpsteer. The tie rod ends were designed to be level or just above angle with the front lower A-arms to remain centered with the wheel hub. In many cases on severe drops the tie rod ends are now at a negative or upward angle below the hub. With this upward angle anytime the suspension travels upward from a bump the wheels go Toe in (cross eyed). No alignment in the world can fix this,.. not even with caster camber plates. Fox body cars tend to suffer from bumpsteer more than SN95 cars do. Bump steer kits relocate the tie rod ends and put them back into the correct geometry they need to be in for the steering to work correctly.

Not all lowered cars need bump steer kits. Much will depend on the extent of the drop and how the car handles after the drop. We had H&R Sport springs on my wifes 96 Cobra with 1/4 coil remove on all 4 springs. The car was low. But never had any bump steer issues and never used a bump steer kit or CC plates. Each car is different. Take it one step at a time. Only purchase what you need to have, unless you have money to blow then knock yourself out.
