I can recommend this DIY body-shaker kit.

You'll need a spare sound card output and a few leads. Also a way to attach the shaker to the underside of what you sit on which is an office chair in my case. Attach it with some spacers to provide a bit of a gap between the chair and the face of the shaker.
I was using it on one channel only but to get around this you could either use 2 shakers or, like I've just done, merge the 2 stereo feeds into one with a few resistors - http://www.rane.com/note109.html Figure 2 for your average sound card output.
Feels really good with the bike ticking over and going over kerbs etc. Will also work with any other game or music, BF4 is amazing
