I've got the R4-S set on my 987s Boxster, have done 1 auto-x and 1 track day and like them over the stock pads.

I've used them before on other track day cars and had to deal with some intermittent noise, but no such issues in the Porsche. Just be aware that their dust is brown, not black. But they do dust less than the stock pads.

The place the Craig recommends for the front pads has some of the best prices for Porterfields, but not as good as the price that Craig has here.

(Sorry Craig, I know I said I was going to get a set of Pagid's but came to the realization that I don't really need that level of grip for my current driving style. Maybe if/when I get more serious I'll go with Pagids).

Thanks
