I looked at the Mugen. It's a pretty interesting design as well; however I think the Durango, as Gregg pointed out, is exceptional.
I'm like Gregg. While the changes might mostly be cosmetic, there's something about a well machined piece of metal that screams "quality" and "engineering" to me. It doesn't mean it's better, but to me, it seems to be made to a higher standard.
For example, when I designed the brake caliper brackets for the front brakes on my track car, I could have designed a no-nonsense brake caliper bracket like you find on the (very high quality) StopTech kits:
However, I thought that since I'm having mine custom machined, why not do a little analysis to see where I could lose some weight while keeping an adequate FOS (factor of safety) given certain design criteria. After several prototypes, I ended up with this:
I also did something similar for the rear.
Yeah, I know, the Wilwood calipers aren't as nice as the StopTech's; however the Wilwoods work very very nicely, and the pads are almost 1/2 the price of the pads for the StopTech's ($155 vs $290!). Not to mention that the rotors are cheaper as well ($170 vs $230 each), and I was able to use a thicker rotor with the Wilwood setup (1.25" vs 1.1"). You go through pads and rotors much more quickly than calipers.
