brake pads
I just replaced my front pads & my rear pads still have some life left. Is it all right to run different pads on the front than on the back?

If the pads are correct for the car it is ok. That is I've never come across any caution from Porsche against doing this and I've done it -- often changing just the front pads -- and never had any issues. Seems like every time I buy pads I get a different brand though still the correct pad for the car.

Let's be a bit more specific. You want similar friction properties front and rear. It may not matter (much) if fronts are new and rears are old, if they are the same pads, same manufacturer, same model/coefficient. If they are different, you can upset the braking balance - enabling either front or rear to lock (yes, your abs will partly to mostly save you, but it means compromised braking and some lockup on the track).
Finally, you want more than "some meat" for the track, unless you have track pads. Not only will they war frighteningly fast, but pad material is you insulator, protecting your fluid from boiling.
PCA DE rules are 50% or better. There is some room for interpretation based on pad material, driver level, etc.

Ok, so up front I put new Pagid Black RS 14 pads on and on the back I have my old Cool Carbon Performance pads with 60 % left. I have the rear Pagid pads on my work bench. Just wondering if I could get one more track event out of my old pads but, the last thing I want to do is sacrifice safety.

Unless you want to look up the coefficient of friction vs temperature curves, i would not. Some experienced racers intentionally stagger pads, but they do it (supposedly) knowing what they are doing. I would never mix and match randomly.

But "racing" or high performance or special pads are a different thing altogether.
