sounds like a freight train. This should be a TRACK ONLY pad.
i was warned by my mechanic, and warned by some users on forums, i didn't think it would be that bad. but my god. this thing sounds like a freight train crossing mixed between a dying cat. on the freeway it's a lot quieter at 70mph, and stops on a dime, but NO ONE SHOULD BE GUNNING DOWN THE STREET EVERYDAY AT 70MPH. i gave it three stars because the description from manufacturer is a bit misleading saying this is a track pad for street. i would say this is definitely a track pad ONLY.
