I much rather love the B+M plate style, actually; have had it in my 924 for ages. A number of guys use 'em in the DSRs, in fact. Much cheaper and more robust than the uber-expensive Mocals etc.

In the 924, it's a similar location as the RX8, sounds like - up front, corner, in front of the front left wheel. It's been in a number of tire walls and gravel traps, thanks to the new/current driver (oh, yeah, and me once or twice too). It still works great, just have to poke out all the gravel on occasion.

Excellent cooling too, IMO - car works great in 95 deg heat. With the 924, it's the 8.5x11" size... YMMV...
