I just came from a local well known custom suspension shop. He's is recommending a bump steer kit when he does the alignment on my car and adding 1/8" wheel spacers to get the rims away from the UCAs. When I asked why regarding the bump steer kit, he said "its just good practice" and will assure no "sloppy, squirrelly" feel in the steering.
I thought this feeling that I have experienced was the nature of a short, light car with power steering.
This is the first time I am hearing this could be bump steer. (Used to modern cars)
I can appreciate the value in the 1/8" wheel spacers but bump steer kit?
Would this actually resolve the feeling in my steering or is this the nature of our platforms?

They're available locally for ~$300 CAD so rather not spend the money needlessly
