DIY: Porsche Brembo Experts Help!

[Cronenberged]

A friend of mine has some Porsche calipers. 425 & 426 fronts from the boxster S, but the other 2 rears I’m not sure if they’ll work and they’re not in Polars DIY.

Update; have a good laugh 🤣 his wife sent him the brakes lines and bracket P/N not the rear calipers.
