HP plus are always my favorite autocross pads. Predictable, with good initial bite and progressive feel. Make sure you lay them down as recommended and they will give birth. I use these in Wilwood Super Light calipers and if you do the same make sure you order the correct thickness. I learned this the hard way, no problems with regular calipers. If you are concerned about brake dust, these pads may not be for you as their performance is excellent.
