I've got a fire extinguisher stashed behind the passenger seat, but thought I'd get a more "professional" looking setup.

I think I'm up for the Brey Krause setup.

Looking at the R-9520 quick release and the R-2020 mount and maybe a new halgaurd fire extinguisher.

Anyone have any recommendations for a good place to buy these online ?

Of, if you have something that's better then the Brey Krause setup, I'd love to hear about it.

 

BK is your best bet unless you have a rollbar that can be used for mounting. I think ebay sometimes has it and all performance shops do too. If your car is stock, you probably don't need one though.
