I had my local shop EuroPower Houston make a custom bracket to fit my Mclaren 600LT's driver seat in my M6 for track days. It is possible but depends on how much you actually want to spend to get it done. You will need to purchase an extra seat belt as well, I got mine off eBay for $43 shipped and had it rigged to work and pass track inspection. I've been tracking the M6 less and the Mclaren more so I might not need the seat bracket anymore.
Here is the post that inspired me to give it a shot.
