Fire Extinguishers

After watching a bud's car burn at the track (not a mustang, got stuck in the mud after spinning off and the hot exhaust caught the grass clippings on fire under the car), I may be in the market for a fire extinguisher.

Any recommendations for something for a near-stock S550 interior? (i.e. no rollbars to bolt to)

A-B-C rated dry chem or foam system.

This is what I use:

It will limit the seat from travelling to the forward most position. And I had to modify some of the plastic around the seat base to make it fit.

I use the SpeedTactics mount and Halguard 2.5lb extinguisher.
