I about gave myself whiplash when I was backing out of the garage & tapped the brakes for the first time.
Huge difference with the new setup vs stock. Much less pedal force & travel required.
I've only had the stock pads on this wrx.
Took it out to a deserted road last night and did the bed in of 7 medium stops, from highway speed, drove another 10 mins, did another 7 medium stops, then did 6 hard stops just at abs activation.
Initial bite feels good, it's not to grabby, but add a little more pedal force they really bite in and hold.
I drove from Denver, up to my place in the mountains. (I'm at 9200')
There are two long downhill sections, like 10-15 minute long. With the stock setup I was really careful not to heat the brakes to much, and still I managed to warp a rotor.
I tested these out much more than I normally would. I couldn't really tell a difference between cold(it was about 50deg outside), or when I had really put some heat into them.
No shudder or squeaking from the pads(so far), and I left the shims out of the front.
I really like them.
Great service from the guys at KNS too-thanks for sending them out so fast.
