Swiper.js - CMS Slider Headache!

I ended up getting Swiper implemented. If you are pretty familiar with it I could probably still use help, but if not no worries. I have a free form slider that I have set to shrink a little on mousedown via css. My problem is it scales the swiper wrapper and container I think because of how the slider is programmed to be dynamically sized. Do you know if there is any way to shrink just the wrapper that holds the items? I would like for the container (the mask) to stay 100% wide but just the contents to shrink.

Here is an example, down the page a bit in the “fid your fit” section
