I've gathered quite a bit of info on the Seat Sport calipers so thought I'd put it all in one place in case it helps others. Maybe someone can make this a Sticky? The calipers are 4 pot fixed calipers made by AP Racing and supplied direct to...

Thanks for compiling all this info—it’s incredibly helpful for anyone working on these calipers! The details about pad compatibility and the retaining pins are especially useful. I’ve also heard of people running into trouble with seized retaining pins on AP Racing calipers, and your mention of corrosion on the bridge bolts/sleeves makes a lot of sense as a potential culprit.
When I faced similar issues, I found soaking the pins with penetrating oil overnight and applying heat helped free them, but in some cases, cutting them out really was the only option. As for replacements, if the Seat fitting kits seem too pricey, I’d recommend looking at suppliers of
used auto parts—sometimes you can find kits or even spare calipers at a fraction of the cost.
Also, the tip about Ferodo DS2500 pads is a gem—I’ve used them on other setups, and the performance difference is noticeable. Definitely worth considering for anyone looking to upgrade.
Thanks again for putting this together! Making it a sticky would definitely save a lot of people time and frustration.
