Do you need that aggressive of a pad on both axles? Part of why I like the 2500s so much is that they're good enough for the rear that they don't need to be swapped back and forth.
So that's the thing... I'm not really sure yet until we try something
Pretty sure the stock brake system uses similar compounds front and rear.
Actually looking at the two charts it looks like the ST43 out back may be a pretty decent match to 3.12 fronts... Have to convert deg between them.
Deg C / Deg F / 3.12 mu / ST43 mu
200C / 392F / 0.50 / 0.55
300C / 572F / 0.52 / 0.525ish
400C / 752F / 0.53 / 0.53ish
500C / 932F / 0.54 / 0.535ish
600C / 1112F / 0.54 / 0.535ish
I don't think the ST43s on THE REAR will get much over 300C.
I imagine the fronts are over 700C based strictly on me losing pedal feel... The torque drops off like a rock above 650C on DS2500s, where the 3.12s just keep going flat across not fading.
From the looks of it cold, they'll be a bit grabby but hopefully the electronic brake force distribution will be able to pull pressure from the rear to compensate a bit easier. As a general rule of thumb those systems can lower pressure easier than adding it.
I'll have to get another set of rotors and those pads to try before next time out.
Also need to get some temp paint. Any recommendations?
