How many drivers does a buggy have?
So let's just say I'm drivin' this buggy...
and if you fix your attitude you can ride along with me.

Yes, that's it. Thanks. Post #13 on that thread by @Beeatnik. That's what got me wondering but I've been unable to confirm.
My experience -
1. I have the Red badged Record calipers from 2015 and have just bought the latest Chorus calipers for additional clearance on my 65.1 for extra clearance on the front (rear was OK)
2. The Potenza calipers also have more the same additional clearance to the latest Chorus calipers - I've bought these for my Helium SL as needed extra clearance on the back
3.The extra clearance is approx 3-4mm height!
4. I also found the my 2015 Records were too low when opened up for my Bora Ones (wide outer of 24mm) basically, the extra width required meant the arms were lower in height on the centre of the caliper and subsequently to low!
5. On the rear the old Single pivot Record caliper allowed an extra 1-2mm height clearance but nothing like the later Chorus calipers. Besides I wanted dual pivot F&R
I don't believe the latest Record/S Record calipers have been updated for the extra clearance. Someone please let me know if I'm wrong, as its a slight irritaion that I've had to 'downgrade' my Record Groupset to run 25mm and wider wheels!
Hope this helps
PS - Agree with previous poster, the bearing Records have a smoother snappier feel at the lever...maybe marginal if set up well though!
@sleepless: Your pic is great, but without a similar pic of the SR caliper on the exact same setup, I can't tell anything from it on a comparative basis. Even then, the clearance difference, if it does exist, may be very small but a small amount is all I really need. If there truly is 3-4mm difference as @roadhog44 is suggesting, then I need to pick up a set.
You'll notice the later brakes have more pronounced smoother scalloping out around the R/H pivot bolt. This realisation now means I can now fit Crudracers and 25mm tyres on my Caad9 for winter too! I wonder how many Campag brake clearance issues are blamed on brake bridge/fork issues, when actually...they could be solved with Chorus or Potenza calipers!
Note - Chorus calipers come with the same Record pad retention clip on the holder and the Potenza now has a Shimano style screw, and subsequently different pads like Shimano fitment now.
Yes -100% I've easily got another 3mm extra height clearance now with the Chorus calipers, plus better general clearance around the outer width of the entire tyre too! There is a definite difference in the look of the later calipers too. These early ones http://www.wigglestatic.com/images/campag-cpb910-11-zoom.jpg are completely different around the R/H pivot bolt!
Also, the later ones have a screw in brake adjuster as opposed to the old one the was dependant on the adjusting nut for movement.

what is the difference in brake feel?
I've got athena skellys with bxps right now and want a sr/record/chorus to match the rest of my groupset.

Thanks @Sleepless, but at this point the only way I am going to satisfy myself is to compare the two in my own scenario. A set of new Chorus calipers is on its way. I will report back with two pics of same bike, same tire and wheel, same exact adjustment, same camera angle. One showing Chorus. One showing Super Record. Maybe by the weekend if they get here by then. Certainly by early next week at the latest.
