My Raybestos ST43 Experience

Just a data point that might be useful to folks having double-duty cars.
Wendy at Porterfield explained to me that the Porterfield street pads and the Raybestos race pads share some of the same material and recommended I try just doing pad swaps between street/track. Typically I had kept a set of rotors and pads for street and another set of pads/rotors for track because rotor sharing always ended badly with other brands/types.
With the ST43 and the R-4S, I have swapped pads only several times now with no problems.
Yes, on full race cars, I run 47s, but on a double duty car, the 43 has been fantastic.
Maybe this option will work for some of you.

Do you have the OEM brakes with padlets? I also tried ST43s with those brakes back in the day, and the noise drove me crazy! Later, I switched to StopTech BBKs front and back with ST43s, and all was good.
One observation I had was that when it squeaks, it's usually the rears.

One of my instructors is running a stock 2013 zo6 with st43s and dba t2s and no noise what soever

Have you taken a drill with wire brush and really clean the back of the pads where they make contact with the pistons, then brush on Permatex anti squeal to the back of the pads and let it dry before assembly?Also keeps the pads from rattling if they are little undersized in the caliper. I run them at the track, non of the crazy noises like yours BUT around town they will make noise at every stop light

And that dust you see; that's your rotor. The ST43 is NOT a street pad....noise, dust, wear...ditch them and put in normal street pads like you should be running.

Creates a silicon barrier between back of pad and caliper pistons, keeps pads from rattling and reduces screeching. I used to just brush the stuff on wet and assemble, but then the stuff can stick to brake dust boots and the 1st time you drive the piston push the material out of the way. If you let it dry before installing pads it works great
