Here's a few idea's (in no particular order) that might help some of you looking to put a racing setup together.
Bob Earl Racing Chassis with a
mounted behind the seat.

Buttkicker mounting template.

Warcrime built this one himself...nice!

TreeTopFlyer's setup...simple and clean.

B1GDAD's setup. Again, simple and clean.

Greyfox's setup. Simple and seems to work really well.

Turbo X used a simple folding chair.

My personal favorite is this one designed and created by Uniball.
