FYI just thought you guys would be interested, I'm going to have a crack at installing some tactile transducers under my chair so I can feel the rumble, gear change thump etc.  Apparently it goes very well for a VR setup. I thought I would document the install and parts list if it benefits anyone else.

I've gone the cheaper DIY option rather than forking out for the buttkicker, and the below setup is going to be alot easier to expand if I want to.

I just ordered
- 2 x Dayton Audio BST-1 bass shaker transducers ($180 for 2 delivered)
- 1 x 24V/10A power supply ($29 delivered)
- 2 x 100W Mono channel TPA3116D2 amplifier boards ($26 delivered)
- 4 x 40mm x 40mm Female/female isolation bobbins for my sim chair  ($42 delivered)

When I get it I'll make a little box up, so should be able to do the whole install for <$300, and that will be 2 x transducers.

Will update when I get the parts / start the install.

Should be good Scott, price is right .

Nice, I just set mine up. Stereo channel amp for individual channels for front/rear (pedals/seat). I have a Fosi audio TPA3116 100w x2 amp, 1 Dayton BST-1 and 1 Aura AST-2B-4. Both are 50w shakers and feel pretty much identical so it won't matter which you get. Once dialed in it adds some great immersion and an extra level of feedback that you don't get from your screen, headphones and even the wheel.

Cool!  I'm going for a left/right under the seat setup, because I assume that I will end up really liking it putting some smaller transducers/pucks around the pedals for some front effects to get a full four corner setup.  That's another reason why I went with individual mono amp boards, because they are cheap if they fail, and I can easily expand the system by just adding another amp board (the power supply will be big enough to run quite a number of them).

I bought a licence for simhub this morning, seems the most practical solution other than forking out a heap of money for SRS or Simvibe.

Ok so I'm pretty much done, still a bit of tweaking and tidying up to do.

Was it worth the effort?  I think so, certainly added a level of immersion that wasn't there before.  Would I fork out big $$ for buttkickers, I can't say that I would, although I only have a home made rig so I think the bass shaker setup is comparative of the whole rig really.  Considering I did a 4 x transducer rig for about the same price of 1 x buttkicker I'm pretty happy with the end result.

Final Parts list was
- 2 x Dayton Audio BST-1 bass shaker transducers ($180 for 2 delivered) - 1 under the chair, 1 on the back of the chair
- 2 x Dayton Audio TT25-8 puck transducers ($62 total) - both under my pedals for left and right hand wheels
- 1 x 24V/10A power supply ($29 delivered)
- 4 x 100W Mono channel TPA3116D2 amplifier boards ($52 delivered) - 1 amplifier for each channel
- 4 x 40mm x 40mm Female/female isolation bobbins for my sim chair  ($42 delivered)
- 2 x clipsal 3.5mm wallplate jacks and a wallplate ($15) (to go on the side of the my chair)
- 1 x IEC320 C14 AC inlet with switch ($12) (just to go on the side of my chair)
- 2 x 3.5mm leads to run from computer to side of chair $20

Total $412.

I attached a photo of where I placed the transducers on my chairs, including the isolation rubbers.    Also attached a photo of the amplifier board I made up, that mounts in the box under my seat (you don't see it at all).  The amps do not run hot at all, it is quite surprising how much grunt they have for such a little board.

I didn't take any photos of the puck transducers mounted under my pedals, if anyone was interested I can post a photo. 

Also if anyone is interested I'm happy to share my simhub settings that I'm using, still tweaking it a bit but I'm pretty happy with the results so far.  It is awesome to actually feel when your wheel is locking up, quite handy for adjusting the brake bias.
