4 piston calipers: 2nd gen dimensions vs. 3rd gen??
I have read that the 3rd gen brake caliper dimensions are basically the same as the 2nd gen 4 piston calipers. I have seen pictures and they have some visual differences. I am curious as to if there are any significant dimensional differences such as possibly being slimmer. I ask because I have these for a special fitment and there are some wheel clearance issues. Any information is much appreciated.

^Yep. Just a cosmetic difference, that's it.

The earlier S4/5 caliper was less needful of massage to fit under a 15" wheel I found , the later caliper is fatter (and probably more rigid) and required a bit of file action to fit the same rotor.

Left the wheel alone, nervously filed the caliper. It's going on 20 years ago now, I think it was the outer top edge and lettering - but don't hold me to it now - and you' have to expect wheels will make a big difference.
For some reason, remember the even earlier installation of the S5 calipers clearly, they only needed the transfer port "hump" taken down. Not sure if a stone got caught between the caliper and the wheel, or the wheel flexed enough in use to hit, but it was quite tight and there was a distinct witness mark all the way round on those old mesh wheels.
Subsequently, we got a bit smarter and had dogbones and hats made to make a better installation.
