We bought that magnetic bra on Ebay... it hasn't been delivered yet, but when it gets here we'll let you know how it looks and how well it works. We didn't think it looked that great on the red car in the photo, but since ours is black the bra should blend in a little better. Anything looks better than rock chips, though... and the bra does seem to protect the most vulnerable part of the car's nose.
My RX-8 has lots of rock chips and scuffs right in that same area. I wish this product had been available when I first got that car. Out here in So CA it's impossible to leave enough following distance between you and the car in front of you to avoid the crud that gets kicked up... if you leave a big enough gap, some other driver always jumps into the space!
