I was wondering why the DC5R has the front calipers close to the door instead of the bumper like the NSX and DC2R. I've noticed BMW, Porshe, Mercedes, and other high performance cars have the calipers in the same location(as the DC5R) and was wondering if it was that much of a significant difference. If so why doesn't the NSX have it that way and the DC5R does?

 

I've often wondered why some cars have the calipers in different locations. I assume cooling and weight distribution are some factors. I think some F1 cars have the calipers hanging at the bottom of the rotor for lower cg.

Edit: Found a pic.

Dang, for some reason I remember Yoshi asking almost the exact same question ~3 years ago. It was at the Rose Bowl parking lot I believe, prior to a little "canyon run"...aaah...good times.

 

I've got to go with the weight distribution idea an possibly the type of suspension as well.

I'd think there would be some cooling benefit as well, since the "back" part of the wheel opening would most likely have better airflow through that area than just behind the rim in the front.
Then again, what would I know?

 

I believe Porsche says they put it at the back so air can flow across the rotor.

What do those cars have in common? Strut type suspension (I'm positive that's the case for BMW, Porsche, and the DC5R, not positive about the Merc I think they use multilink)

But I think it may very well play a role here...
