Interesting, I've never heard of the Strut-plus. From this video,

it just looks like it includes the spring, mount, bumpers, etc...for maybe 230 a piece.
I dont know how these mounts are, but ppl have said KYB mounts are terrible (I dont know if these are better). I'd suggest sticking with OEM on that one. I doubt you want to lower your car since you would be considering these.
These are pretty pricey, so it might be better to get just the struts and see what parts you can 'salvage'. You might need new bumpers, insulators because they are rubber and the ozone in the air kills the rubber. I doubt you need mounts since the roads there aren't too bad, just be sure to re-grease the bearings on the front mounts!!!!
