Brake pad question for the track guys
My question is: Do you run the same pad compound both front and rear? Is there any reason not to run a less expensive pad on the rear? I understand that different compounds vary in initial bite, but would this effect front to rear? I was considering using my Porterfield R-4S pads on the rear and Hawk HT-10 up front.
Any input would be greatly appreciated.

Yes I run Hawk Blues on all 4 corners, BUT.....I have an adjustable brake proportioning valve inside the cockpit. Because of this I do not run the factory valve which is on the master cylinder. My valve is a Wilwood. They do not cost much at all.

I have run the Hawks in the past and had problems with the pad compound separating from the backing plate. I currently run Pagid Blacks upfront and Pagid oranges in the rear. I do have the Big Blacks upfromt and Medium Blacks in rear with the alternative bias valve to add more rear braking.

Might as well ask about religion and politics!!
The answer depends on tire selection and size, suspension set up, cooling ducts, and even type of track.

More common to run the same pads front and rear.
As long as the bias / prop. valve is correctly setup for the car, running the same pads front and rear is generally the best way to go.
If needed, you can somewhat change bias tendancy by running different compound pads in the back (but this is less than ideal for various reasons).
If your car's brake bias is already balanced, and you run a cheaper or lower friction pad in the back, you will be giving up a little straight line braking power. It wont be a huge difference on a 944 (which uses mostly front brake), but it will be a subtle decrease in stopping power.
Do you still have the stock 18 prop valve? If so, the car is already front biased, and you can use all the rear pad you can get. If upgraded to the 33 bar or 45 bar, you may want or need to run a lower friction compound in the back (especially with the 45 bar valve, and/or if you tend to do a lot of trail braking in high speed corners).
But with that said, I have run cheaper pads for DEs (both front and/or rear) and put in the high end pads for races.
