The big brakes are fine for the street, Wilwood or Sierra. I use the soft Hawk pads -- they do fine for the street, and work better the warmer you get them. I don't have the "pop, click" noise, but they will squeal a bit when cold. If you want to see some nice pad graphs for temps, click here: Pad Friction Graphs

Thanks Patrick. The ERA guys sure are on top of things - especially for a small company. I checked out the graphs in the link. Am I interpreting this incorrectly, or does it look like Polymatrix A has a higher coefficient of friction across all temps (100-1300F), versus all of the others, and should be the better choice, unless the wear is significantly worse? But those pads are intended for racing only, and not street use.

Be careful about those graphs as you can drive yourself crazy with information overload on things like initial bite , coefficient of friction etc . Just call Wilwood ( if that`s who you go with ) and tell them type of driving , car weight , rotor material etc and ask for a pad recommendation . I use Hawk pads for the street , called them and used what they recommended . In my experience , stay away from racing pads for the street . Racing pads generally need a higher temp to really come into their own and are more aggressive on the rotors . On mine , it takes about one lap for the pads and rotors to really start working . On the Hawk street pads , they work from the beginning with ok pedal pressure on the street .
