Hawk has several compounds available.
King Motorsports has recomended the hps
compound for street driving and the 9012 blue
compound for track use.The 9012 blues are very
agressive on rotors if used on the street.9012
needs temp to work properly and on the track is the
only way to get them up to temp driving,on the street
will not do it.Call King and they can discuss the best
compound for your car and driving style.

Hey everyone-

I found the Porterfield R4 to only be aggressive enough for rear pads. We've killed off a set of them in a couple of sessions, sometimes not even one track day. You're experience may not be the same, however.

I use Hawk Blue pads on the front of the S2000 for track events, OEM pads for street- too lazy to find any extra stopping power for the street...

On the other car I use Pagid "reds". We're trying the orange pad soon, the "blue" Pagids are too caustic for the rotors we use. We've had poor luck with the Porterfield R4 pad on the front of this car. We use Porterfield R4 pads on the rear brakes here too.

Performance Friction has recently discontinued their PFC line, hence no recommendations from me.

We've found that good ducting and fresh brake fluid make the biggest difference to the brake system. Good luck on your search for pads...

Annie and I put Porterfield R4 pads all the way around on our car. Contrary to what others have said, they don't really take that long to work well. I say that mostly because even at their cold temps they seem to work as well as the stock pads do when they are hot! They work incredibly well, but the rears eat the rotors big time! We've gone back to putting the stock rears on for the street, but we're leaving the fronts on all the time. The better braking is awesome!

We also have R4S pads on our A4. I haven't been as impressed with them, but I think our problem there is more one of old rotors.

about how much fluid is needed to completely flush the brake system and add a different, new fluid? there is an open-track day coming up so i got the pads. i also wanted to dump some higher temp fluid in the lines. thanks

brianb - That depends on how compulsive you want to be . I usually run 2 16 oz. cans of fluid through the lines when I purge/bleed before track events. It's a good idea to buy some extra to have on hand at the track *just in case*.
