Fox Struts Needed For B-springs?

I just read another thread where someone mentioned fox springs for a lowered car. I have frpp b-springs with no isolators. I have about a 1.5" gap between the tire and fender.

Ive noticed the strut will bottom out on larger bumps at higher speeds (they do have 106k miles on them as well) Would I benefit from fox struts with my drop?

I should add that I have MM CC plates, but the shop that installed them put the spacers in for stock ride height and not a lowered car. If I get the spacers set up correctly than maybe I wont need the fox struts?

edit: thinking some more... fox struts are 1" shorter so then I could run them and set the spacers up for stock ride height since I wont need the additional 1" from the CC plates.
