Essex Designed AP Racing Radi-CAL Competition Brake Kit (Rear 9450/365mm)- Toyota GR Supra

"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.

Features

  • 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.

Benefits

  • Approximately 22 lbs. of unsprung weight reduction from the rear of the car
  • AP Racing Radi-CAL calipers are the stiffest, lightest, and most technologically advanced calipers available at any price
  • Calipers use a 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 one bolt, 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, 72 vane, fully floating, AP Racing J Hook racing discs
  • Anti-knockback/anti-rattle disc attachment hardware
  • Replacement iron disc rings available at an extremely competitive replacement price ($375 each).
  • 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
  • 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.

Applications

  • 2020 - 2021 Toyota GR Supra

What's In The Box?

  • One pair AP Racing CP9450 Radi-CAL Pro5000R racing calipers
  • One pair 365x30mm AP Racing CP8972, 72 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.
  • 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.

Warranty

  • No Manufacturer Warranty
