+1 on the logo look... my calipers say FoMoCo on them (but at least you can't see it with the wheels on...)
I believe MSP rears and FD rear calipers are the same... and 626 V6 calipers
I've got 2007 mazda6 rotors/calipers front and back on my car, really i feel like there isn't much of a difference between my "new" brakes and the old ones that came with my protege ES. Of course, that's just me and i might have simply forgotten the feel of my old brakes... the very next day after i ditched them. I'm glad my rotors aren't warped now, the mazda6 rotors don't want to warp as much as the protege's old rotors did...
The width of the pad on the 2007 (and i think that applies to 2006+ as well) mazda6 brake...pads... is almost the same as the width of the old protege pads, but the mazda6 pads are a little longer, and the rotor is of course much larger.
Our mazda3 and mazda5 feel like they have way more stopping power... probably due to the larger rotors and pad surface area. The pads on the 3 and 5 cover the entire rotor surface, the pads on the mazda6 leave you with around a centimeter of rusty unused area that you look at every day before you get into your car and then you look of the other mazdas in an attempt to figure out why the OEM look involves some rust band.
But that's just me... maybe i still just can't tell the difference between the old and new ones. What's the pad size of the FD's brakes compared to the MSP's?
It's almost worth it to have a nice set of calipers that say mazda on them... and not-warped rotors...
