Us socal guys will fade pretty much any pad on the market with street tires on at Auto Club Speedway. You spend something like 40+ seconds going 100+mph to cool the brakes, and they'll still fade. Virtually everyone has brake ducts.

It has less to do with pad compound, and more with deficiencies within the S2k's brakes relative to the grip levels available now.

 

Checkout the Kognition wing:

This wing can be made to any width or height you specify. It's carbon fiber not fiberglass wrapped in one layer of carbon fiber like the Voltex and APR. It's also stronger and proven by some of the fastest time attack cars in the world.

 

I've seen their wing in person, and its absolute crap. I would never run it on my car.
