Yes, the Mintex (semi-metallic) pads I got come with holes for the wear sensor. I heard some racing pads don't come with those sensor holes. You should be fine.
I bought these Mintex pads off ebay 2 years ago. Never was able to figure out what this "red box" thing meant. Dont know if these are the red box pads. Anyway, they did not have the holes for the sensors so I drilled them.
Hey Toolpants,
Yup--did the same thing....drilled those holes. IMHO, for the price, they have been decent pads for me so far. BTW, do you still use the Mintex brand or have you found something else that works better for you??
