Going back to the AP Vs Brembo discussion, if you don't know Brembo purchased AP Racing about 4-5 years ago. And it seems that now it's all down to marketing where you see each of the brands being used!!!

It's all down to brand management now, and from what I have seen on the new Brembo racing equipment, you will begin to see more and more Brembo branded racing products which have historically been in the AP Racing category.

Pratically speaking though, both brands are excellent and between them you will be able to find a product that will suite your purpose.
