Is this frame a good option for a lightweight build?

Hello all, kind of new to this so apologies if this question is dumb. I've been searching for an inexpensive base on which to build a small lightweight build (maybe foamie). Anywho, came across this on a local selling forum and was wondering if I could modify it to work. My main concern is the apparent lack of suspension. Thoughts? Advertised as being 4x8 in terms of dimensions. Here are some pictures: https://imgur.com/a/LR37RNt
Again, sorry if this is dumb, just trying to make a good choice. For context I have basic welding skills and am not afraid to purchase additional tools. Thank you.
