I'd heard the same but assumed it was just what the AP fanboys were saying to justify the extra grand they spent instead
I went for the 8 pot 356mm kit, very impressed. Used them on track (Nurburgring and Goodwood so far) and no fade with bluestuff NDXs, even after 15-20mins constant abuse.
The other thing i've been hearing about brembos lately is damaged threads when being removed from the old car - a lot seem to need re-tapping.
