Interestingly, the PFC-06's I bought recently do have the retaining clips so that will end the rattling. I haven’t used these yet as I still have a couple of track days left on my 01’s. Most people who install race pads for a weekend don’t connect the brake sensors.
My question is why would want to use race pads for the street? I don’t see any big performance advantage that would outweigh the lack of braking with cold brakes. You can’t always keep your brakes at temp on the street and if you need to stop quickly you’ll be at a disadvantage. You’ll get tired of attracting attention with squealing brakes too, though you may get a grin from watching everyone run to the curb with their trash bags.
