Again...there is no such thing as a "street/track" pad. It doesn't exist. What DOES exist is clever marketing phrases like "A TRUE STREETABLE TRACK PAD" or "SATISFYING LIGHT BEER".

The 309's get somewhat close to being a "track/street" pad...but they fall VERY short when used for track. You'll be compromising quite a bit on that end as compared to a real track pad. They're prone to some crumbling when pushed past their temp (they're organic) and they're not entirely stable for track temps when using the stock braking system. I sure AF wouldn't use them on anything faster than a stock S2000 on 300TW on a track.

On the street, they feel like factory pads in terms of bite. But they're very gentle on rotors and the dust washes off super easy.

The PMU is geared more toward track use, but you'll be giving up rotor life and the dust will potentially stain everything you hold close.

Either one WILL need a proper bedding procedure before you can use them without fear of death.

PST = less aggressive compound
PSA = More aggressive compound

I've used both for track days and both have great street manors as well. They both dust quite a bit though....gotta have a trade off somewhere. My front PST's are still going after ~10 track days last year w/ front brake ducts. Had to replace the rears after the whole season though.

It may be my only track day come January next year for another 6 months or so. I don't think I wanna hit said track with my EBC fronts on about 20 percent life left... especially after what you said. Perhaps the 309 set will hold up for my first run and as you said are quite streetable. Who knows if I'll even get up to 1400 F the first time...
I'd like a little more bite than factory on street,,, or would I. Will the 309's inspire more confidence on the street than factory?

Which rotors will resist the PMu or similar semi-metallic pads?

What bedding procedure did you follow?

Thanks.

Rotors are rotors. Maybe a high carbon rotor would resist abrasion? But the cost outweighs any benefit.

Just buy heaps of cheap rotors. I certainly do. There's no real benefit in spending $$ on rotors, if you're tracking this car. Centric makes a reliable, cheap rotor. Its not like the PMU will wear them out every day or something. They will just wear significantly faster than normal.

Bedding procedures are on/in the box, usually. Should just be successive aggressive stops followed by 15-20mins of cooling.
