Tesla Model 3 AP Racing Competition Brake Kit (Front 9668/372mm) Designed by Essex

AP Racing CP9668 Radi-CAL Pro5000R Six Piston Calipers: “Radi-CAL” is a blanket term used to describe AP Racing’s patented asymmetrical brake caliper design. Radi-Cal technology is grounded in Computer Aided Design (CAD) and Finite Element Analysis (FEA), and allows for organic, alien-looking designs that are a radical departure from conventional caliper designs of the past. Radi-CAL's are widely considered the pinnacle of current brake caliper technology. These Pro5000R calipers are direct descendants of the current crop of F1 and Sprint Cup calipers. They don't look ordinary, because they're not ordinary. They're the epitome of pure racing design: elegant, sparse, and brutally effective. And while they embody and employ the Radi-CAL design philosophy of the past, they also add some outstanding new features that enhance their practicality, convenience, and appeal. Quite simply, they are the lightest, stiffest, and most technologically advanced brake calipers that have ever been within the average enthusiast's grasp.

Essex Caliper Brackets & Hardware: Caliper brackets for our kit are machined from heat-treated 6061 T6 billet aluminum, and hard anodized, ensuring strength and durability. All included hardware is of aircraft quality, and identical to what we use in professional racing. The brackets also typically include helpful tips for install, such as which direction should be facing the disc.

AP Racing J Hook Discs: AP Racing J Hook discs have achieved near-legendary status in both professional and amateur racing for their durability and crack resistance. They have been proven time and again, winning many races and championships (ALMS, Rolex, Grand Am, etc. While the discs we're employing in our Road Kits have an impeccable racing pedigree, we've also added some features that will keep them composed and well-mannered on the street).

Spiegler Stainless Steel Brake Lines: Our Competition Kits include a set of the highest quality stainless steel brake lines available. Spiegler lines have a wide range of features not available in competitive offerings: A stress-free torsion fitting system, abrasion resistant coating, Du Pont Teflon lining, and heavy gauge tightly woven stainelss steel braids.


  • AP Racing Radi-CAL calipers are the stiffest, lightest, and most technologically advanced calipers available at any price
  • CP9668 calipers use a 25mm thick, commonly available brake pad shape
  • Simple pad change with two bolts or quick-change spring clip, no caliper removal required
  • Championship winning, 84 vane, fully floating, AP Racing J Hook racing discs with 12 attachment points to hat
  • Anti-knockback/anti-rattle disc attachment hardware
  • Disc metallurgy specifically designed to handle the temps typically seen on track offer a long service life
  • Highest quality, Spiegler stainless steel brake line with clear sheath that reduces compliance over OEM rubber design
  • Designed to work with OEM rear brakes or our Essex/AP Racing rear BBK


  • Approximately 2 lbs. of unsprung weight reduction, despite a considerable size increase over stock
  • Ventilated, domed back, stainless steel pistons keep heat out of the brake fluid and provide an ultra-firm pedal
  • Mitigation of pad knockback via anti-knockback springs behind the caliper pistons
  • Anodized caliper finish that is resistant to wear and deterioration at elevated temperatures
  • Stainless steel caliper hardware for a long caliper service life under frequent pad change conditions
  • High temperature, low drag seals that will hold up to track temps= less rebuilding and longer service life

Please Note: Brake pads are NOT included with this 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 they want.
