I am sure they are slightly cheaper material, but in all honesty they should be okay. Think of them as the cheapy autozone pads on your car, you wont be able to track em for sure.... But you can't really pass up the deal.

The front pads are super super easy the rear pads when i changed mine I had to remove my muffler because I couldn't fit the tools in there :P

 

you can test pilot them and if they work out then we know a really good deal brakepad!
