So today I was at JKM for part of the day...
Initial thoughts: They stop the car. They stop the car
very well. I didn't go hard on (so to speak) as I'm still bedding them in, but they are indeed a mighty stopping force for the Golf; certainly good enough for my purposes (not a track day fiend with the Golf, not anymore). They do haul in the speed with great aplomb. Dunno 'bout fade, but I imagine they're far superior over the tiny stock items.
I'm very happy with them. Takes a bit of recalibration with my foot, but the pedal is firmer and offers more feel (I think). They haul in the car very well, certainly well enough for my needs, and they look good under the arch. Can't ask for much more!
Big thumbs up from me - definitely worth the money.
