Consider using these guys -> http://www.discountbrakes.com/
I just got my order for my rear pads and rotors. They were $75 cheaper than a well-known Focus parts supplier, for the same parts! Wish I would have used them for my fronts last month.
Wow great website! I was just thinking about doing my rear breaks yesturday because I did the fronts a couple months ago. I checked out the previous website I used and discount breaks was cheaper! So I just ordered the parts and they should be here sometime this week!
From what-ever $6.39 rotor's to some great powerstop 72.00 rotor's! I was looking for some for the rear of my ST! How long are $6.39 rotor's going to last? WOW! I suppose it's better than metal to metal, thou at least for a little while!
