I have auto-x and tracked for quite some time...personally for a weekend car that sees a little track use look into either Hawk HPS or HP+...or if you want to go higher end the Porterfield R4S pad is excellent...I have them on my 89 rossa and it is by far the best street/track pad I have ever used
just be sure you bed them in properly or they eat rotors
Those Porterfield R4S pads are pretty damn good. Their customer service is pretty damn good too.
I've ordered a few sets from them at reasonable prices, after originally being recommended by one of my customers that runs some old race cars. He fit them for his QP that had squeaky breaks and it worked great.
