Brake pads are NOT included with our system. Racing brake pads are a highly personal choice. Many manufacturers include a set of inexpensive, low quality pads with their brake kits. Rather than artificially inflating the price of our system with a set of pads you probably don't want anyway, we've decided to remove the cost from our system and allow our customers to choose the pads that best suit their needs/wants.
Pad Tension Clips (frequently referred to as anti-rattle clips) are NOT included with our Competition Kits, but we do offer them as an option if you're concerned about NVH. One of the great benefits of the AP Racing calipers in our system is that they are designed to accommodate pads from a wide range of manufacturers. Each manufacturer builds their pads with specifications that are slightly different. As such, pads from different manufacturers, or even from different batches, won't always fit in the calipers in exactly the same manner. Some pads are a snug fit, while others may rattle around and produce noise. The Essex Designed Pad Tension Kit is designed to dramatically reduce pad movement inside the caliper, along with just about all resulting noise.
