Ive been running my Hawk HPS front and rear now for a couple months. Ive taken them on a couple runs during that time in addition to regular street driving. Performance is slightly better than stock once they are heated up. They do tend to squeak a little bit from time to time, but if you get the stock pads hot enough, they do too.

The most compelling reason to buy these pads is because they leave almost no dust on your wheels!! I garage my car at work and at home and am going on about 4 weeks without washing!! This is impossible with the stock pads.

Im not sure how much Street Image sells them for but you can get the front and rear pads at tirerack.com for about $130 shipped.
