ASR has developed components for adapting big AP Racing 4-piston calipers and APR 299mmx32mm vaned rotors to fit nicely under certain 15x8 wheels for Civic, CRX, & Integra vehicle applications.

The ASR 11.75" Big Brake Kit (BBK) will offer a wide array of benefits, while shaving roughly 8 lbs. of unsprung weight per corner on your Civic or Integra be it for street or racing purposes. 

With an incredible array of inexpensive brake pad options, pads are far larger/thicker than stock pads and will last significantly longer than oem style pads. You'll replace your pads a lot less often, saving money in the long-term.

About the Caliper:
Mitigation of pad knock-back due to 4lb. anti-knock back springs in the calipers. The AP caliper finish  is highly resistant to wear and deterioration under high heat track conditions 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 better than OEM components= less rebuilding and longer service life. No dust boots to burn up under high temp conditions. Simple pad change with one bolt and no spring clips (no tapping out the pins as you would on a Brembo caliper).  Extremely compact package for superior wheel fitment.  Stainless steel pistons that keep heat out of your brake fluid to resist fluid fade during extended track sessions. 

About the Rotor:
High airflow, heavy duty AP Racing J Hook brake discs that weigh 5 lbs less than the OEM units despite their larger size. AP Racing J Hook slot design that gives more pad bite/feel, and distributes heat evenly throughout the disc. Disc metallurgy specifically designed to handle the temps typically seen on track offers a long service life. 

Because of their quality and trusted brand name, AP Racing brake systems hold their value well in the used market, and you will get a considerable amount of money back out of them if you ever decide to part and sell your car.

Wheel Fitment

This brake kit has been designed to fit under a 15" wheel, however not all 15x8 wheels are compatible. 

Test-fit Approved:

  • Most Volk Racing *TE37's 15x8 +35 / +32 / +25
    *TE37 OG/SL 15x8 +35 w/32mm 5x114 requires a 7-8mm spacer for decent spoke to caliper clearancing
    *TE37 OG/SL 15x8 +32 w/32mm 5x114 requires a 5-6mm spacer for decent spoke to caliper clearancing 
  • ALL Gram Lights 57DR 15x8 +35 / +25
  • ALL Gram Lights 57 Transcend 15x8 +35 / +25

Test-fit Non-Approved:

  • Enkei RPF1 15x8 (any offset)
  • FFD EVO1 15x8
  • 949 Racing 6UL 15x8

    4x100 Compatible Vehicle Applications

    • Designed for fitment on 4x100 Honda/Acura knuckle assemblies w/ 10.2" sized brake rotors with or without an ABS brake system
    • Fitment on the smaller 9.2" sized rotor brake system Honda vehicles is not compatible (generally base to mid grade model Civics that come without ABS).
    • Vehicles with factory 9.2" brake knuckle/spindle assemblies will need to be upgraded to an ABS knuckle assembly in order to be compatible with this brake kit.

    Compatible Vehicles:

    • 90-91 Civic EX
    • 89-91 Civic/CRX SiR  (JDM)
    • 93-95 Civic EX w/ABS
    • 94-95 Civic Si HB w/ABS
    • 93-97 Delsol models w/ABS
    • 96-00 Civic EX w/ABS
    • 99-00 Civic Si
    • 90-93 Integra (all models)
    • 94-01 Integra (all models)

    * The included hub spacers are for 4x100 applications only. They are placed onto the face of the wheel hub and get sandwiched behind the rotor hat, effectively re-correcting and centering the AP Racing rotor within the AP Racing caliper. The reason behind these spacers is because of slight hub offset variances between 4x100 and 5x114 wheel hubs - 5x114 hubs have a 3mm wider track than 4x100 hubs thus affecting 4x100 rotor-in-caliper centering alignment.

    5x114 Compatible Vehicle Applications

    • Any 92-00 Civic or 90-01 Integra with a JDM Type-R 5 lug 36mm or 32mm conversion (70.1mm register)
    • 97-01 JDM 98+ Spec Integra Type-R (36mm 5 lug 70.1mm register)
    • 06-11 Civic Si (8th gen civic, 64.1mm register)
    • 12-15 Civic Si (9th gen civic, 64.1mm register)
    • 02-06 RSX Type-S (64.1mm register)

    The listed 5x114 equipped vehicles are automatically compatible with this kit; no hub spacers are required (hub spacers only required for 4x100 application).

    Note: if you have a 4 lug or 5 lug converted Civic or Integra vehicle and are unsure of which brake kit to purchase, measuring the hub register diameter will help narrow things down. Generally 4 lug has a 64.1mm register and Integra Type-R 32mm+36mm hubs have a 70.1mm register.
