Buyer beware carbotech pads, I ordered the 1521 pad set from them for 227.00. They don't tell you it's for the front pads only. I called when they arrived and they said if you read the small print you would have known that. How deceptive is that. 227.00 for street pads for one axle is ridiculous.
Pick up a mechanics stethoscope from Auto Zone for about 15 bucks. You'll wonder how you got through life without it. You can go to to shop and put your finger on noise maker for them. The reason they don't have them in the shop is because the mechanics steel them and take them home. LOL
