PRO AIR RC Advice if anyone has used on here?

Anyone run this kit, looks like the same kinda air compressor I wise on my CEN F450 for exhaust smoke. I have done servo suspension in past but been tossing this idea around. Bit pricey though.
Also the second one is by Big Squid

Well that's interesting, but why?

I think the bulk of it would offset any gain from lowering the CG. Just guessing.
