Compared to previous generations of Corvettes, GM definitely took a step forward with the brake design on the C7 Stingray platform. That said, the brake components were still designed primarily with road manners in mind. As you'll see below, there is a considerable amount of room for improvement if you plan to run your car hard on the racetrack.

The OEM Stingray Z51 discs have a few major impediments that prevent them from working optimally on a racetrack:

  • Pillar internal vane design
  • Narrow/partially obstructed air gap
  • Limited airflow to outer disc face
  • Dual-cast construction
  • Relatively low thermal mass given the platform's performance potential

A proper racing disc design differs considerably from the OEM Z51 disc design, and will operate with far more efficiency in a racetrack environment. Despite having the same overall dimensions as the OEM Z51 discs, AP Racing's Heavy Duty J Hook Discs provide superior cooling, less judder, fewer cracks, and an increased service life vs. OEM and competing discs of comparable size. AP Racing J Hook discs are the epitome of endurance racing components, and have been proven time and again in professional racing, winning many races and championships (ALMS, Rolex, Grand Am, etc.). They will certainly stand up to any abuse that you throw at them.

 

Reasonable ReplacementCost

Let's face it, no matter how good a brake disc is, it's still a consumable item. They're no different than brake pads or gasoline. You beat them up until they crack to pieces, then you throw them away. If replacement iron is too expensive, you're always driving in fear, waiting to shell out big bucks for a new set. Despite having the most expansive set of features on the market, our replacement iron rings are completely affordable.

Going to the track is expensive! Event entrance fees, hotels, fuel, and tires all add up. While you obviously want the best product available, you can't afford to pay a small fortune for something you're just going to destroy. You can buy a cheap set of $150 discs for every event, have relentless heat issues, and find yourself constantly swapping them out. When you do the math, the long-term value of the AP J Hook's is tough to beat. You'll enjoy all the benefits without breaking the bank, and you'll spend more time driving and less time wrenching.

Elite level teams choose AP Racing discs because they know the work has been done to provide the best available product at any price level. The AP J Hook is a direct derivative of AP's vast racing experience. You can buy with confidence knowing that you're getting the best product available at any price point. A note of caution however: the J Hook design is often imitated, and there are a number of lesser quality imitations on market. Before purchasing, make sure you are getting an authentic AP Racing J Hook.
