Still have a soft spot for the Sprint and tend to keep an eye on the 33, Sprint, Sud forum. I did hear that its possible to fit GTA 4 pot Brembos to the 33 type suspension
I'm a bit curious, could it have been my brake upgrade you have seen back then?
Or was someone else first?

In late 2006 I first tested my GTA calipers who was taken from a late 147 (330mm) with Fiat Coupe 305x28mm discs on one of my 33 16V on the road. The difference in braking is huge from the original 33. I If someone wounder why I "only" use 305mm discs with the bigger caliper is my answer that I bought the discs before I get the calipers home.
I bought the calipers from an auction at eBay in September 2006. The auction description sad it was the calipers for the 305mm discs. But that was wrong, instead I got the bigger one.
The only said thing about that is that I must use minimum 17inch rims, but then I already got 17inch rims it doesn't really matter.
The bigger pad surface on the smaller discs is not a problem. The pads cover exactly the whole surface on the disc.
I think i am the king of upgraded brakes for Sud/Sprint/33
I am now running a 315x28mm disc with GTA 4-pt Brembo calipers.

I can tell you that you are NOT the only "king" out there
(I don't think this is the requirement for the "King" title?
Your disc may be little bigger than mine but my calipers are just a little bit bigger than yours
Anyway our brakes looks just great but the most important is that the performance are just super!
Once I tested to brake from just a bit over 180km/h to just below 70km/h. It only took a few seconds.
I love to brake late, really late
BTW, I have also tried to find the same type of calipers that Boris is using but my local scrapyard hasn't dismantled that type of car yet.
I want them for my daily 33
You can see the "GTA" brakes fitted on my Sprint in the attached pictures below.
