Just in from breaking them in and here's my impressions.
1st, believe the hype! They make a noticeable difference in braking over stock. When I pulled off the original brakes (and by original I mean that the brakes have never been done before... gotta love a manual tranny) they were in great shape still! Pads were about 1/4 to 1/3 of material left and the calipers were all working normally too. I made 10 high speed stops from 100 km/h to about 10 - 20 km/h. The first 3 or 4 stops had me smiling from ear to ear as the 4Runner stopped almost instantly with the rest of the stops getting longer and longer due to fade but man what a difference! 2nd, as is often reported, application of the brakes is a little later than normal meaning that it takes a little more pedal travel to start to feel the brakes apply. I quickly got used to this and it's not a big deal at all.
Highly recommended!
