Great question. Unfortunately, neither I nor anyone else on the forum can really tell you how it would/wouldn't effect your insurance because that's going to depend on your insurance company and their policies regarding vehicle modifications.
By this I mean, just because something has worked for someone else (possibly in a different state since car insurance laws vary from State to state) does not mean that it will work for you with your vehicle with your company in your state.
So maybe the question you need the answer to is more like this - if you have removed your front seat in your modifications to your vehicle, 1) did you tell your insurance company and 2) if you told your insurance company how did that effect your policy, and 3) what insurance company do you use?
Best of luck,
