AP Racing Radi-CAL 9668/372mm Competition Front Brake Kit by Essex - Tesla Model 3

Complete front Essex Designed AP Racing Radi-CAL Competition Brake Kit for the Tesla Model 3

• Features AP Racing CP9668 Radi-CAL Pro5000R six piston calipers
• 372x34mm, 84 vane AP Racing disc
• Saves roughly 2 unsprung lbs. from nose vs. OEM brakes, despite being considerably larger
• Every component designed to resist the heat of extended track sessions
• Pistons sized properly to allow for seamless integration with OEM master cylinder and ABS system
• Designed to work with OEM rear brakes or our Essex/AP Racing rear BBK

• One pair AP Racing CP9668 Radi-CAL Pro5000R six piston calipers
• One pair 372x34mm AP Racing CP6084, 84 vane, J Hook racing discs, with fully floating 6061 hard anodized aluminum hats, and attachment hardware
• One pair caliper mounting brackets and hardware
• One pair Spiegler Stainless Steel Brake Lines with abrasion resistant coating
• Detailed installation instructions
• 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. When purchasing our kit, you are able to choose one set of front pads at a substantial discount vs. the retail price. 

“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. Since their inception in 2007, these revolutionary calipers have amassed a lengthy string of race victories at all levels of professional motorsport, while redefining brake performance expectations. For more details on the design concept and what these calipers have achieved in professional racing, please visit our blog and read The AP Racing Radi-CAL Story.

The key benefits of the Radi-CAL design:

• Massive Stiffness Increase- A 30+ % increase in both static and dynamic stiffness vs. conventional calipers allows for far less deflection under load, which means superior pedal feel & modulation, more even pad wear, and longer caliper service life.
• Considerable Mass Reduction- Removing all extraneous caliper mass lowers the caliper weight, despite the huge stiffness increases.
• Optimized Airflow- Air moves around and through the caliper more efficiently, providing superior heat evacuation and cooling.
• Efficient Packaging- The asymmetric caliper profile and internal fluid porting allows the caliper to fit into tighter spaces.

Advantages Over OEM Brake System

Our CP9668/372mm Radi-CAL Competition Brake Kit offers our customers the following advantages over the OEM brake system:

• Approximately 2 lbs. of unsprung weight reduction, despite a considerable size increase over stock
• 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
• 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
• No dust boots to burn up
• Simple pad change with two bolts or quick-change spring clip, no caliper removal required
• Lifetime professional caliper rebuilding support by Essex (at a fee)- pull off your calipers, send them to us, we clean, inspect, and rebuild them
• Available disc burnishing service ensures that your kit arrives ready to be installed and driven hard immediately
• 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
• Replacement iron disc rings available at an extremely competitive replacement price
• 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
