Just wondering if anybody could list calipers in order of size. For example are stoptechs bigger then spoon calipers? If so does anybody have any idea how much bigger? (Dimensions)

Here is my wild guess,

Narrow: Wilwood 4 pot
Wilwood 6 pot
Brembo Gt
Spoon Monobloc
Stoptech
Endless
Bigger: Project Mu

But just a guess and I have no clue about others like AP Racing. Thanks

 

I'm pretty sure Stoptechs are bigger than both Brembo and Spoon. Not positive though. That doesn't mean they are better, just bigger. I think your list looks pretty good... Nothing a novice like me can correct anyway.
