Ultimate Kit | Holden VT - VZ

Product Code: BK-ULT-VT

Available Options

Look no further than our "Ultimate" kit to satisfy the demands of serious street and track enthusiasts.

Our 2-piece rotor and caliper design pushes the boundaries of extreme braking to achieve world class performance, with independently tested 100-0 km/h stopping distance less than 35 m. Our 2-piece rotors with aluminium hat on the front, reduces un-sprung weight while also offering better heat dissipation over a standard single piece cast iron rotor assembly.

The Ultimate Kit exceeds the V8 Supercar specifications in several parameters of overall braking capacity and maintains perfect braking balance under all driving conditions.

Front Calipers: 6 Piston lightweight aluminium calipers available in selected colours.
Rear Calipers: 4 Piston lightweight aluminium calipers available in selected colours.
Front Rotors: 381 mm x 32 mm  2-Piece, 48 vane directional rotors with 24 radial slots.
Rear Rotors: 355 mm x 28 mm  2-Piece, 36 vane directional rotors with 24 radial slots.

Vehicle Applications:

  • Holden Commodore, VT - VZ, including HSV variants.
  • Pontiac GTO, 2004 - 2006

Why do I need to Upgrade?
  • If you have fitted a wheel/tyre package that has an effective diameter greater than standard, the brake effectiveness is reduced, the force required on the rotor to slow the car increases by approximately 8% per 50 mm increase in effective tyre diameter. This means the driver needs to push harder on the pedal to stop, and results in increased rotor and pad wear.
  • ABS, ESC/DSC or EBD can't help you under brake fade conditions, the OEM brake systems are designed exclusively for road use and tested to comply with ADR 31/01*
  • If you use your car for any track work, you'll be driving at much higher speeds with much less recovery time and braking many more times than the ADR test. The OEM brake system isn't designed to cope with track work
  • If your vehicle has increased power and torque due to other modifications such as a Harrop supercharger, camshaft, intake and or exhaust upgrades; The faster you can accelerate, the less time you will have to decelerate.
  • A minimum of an 19” wheel diameter is required - Caliper sweep template is available above in the download tab to check specific fitments
  • Optional stainless steel braided brake line kit available at extra cost.
  • Calipers available in red, yellow, black.
  • Custom slotting available for rotors at additional cost.
  • Please note that the installation of aftermarket braking components may cause additional brake noises from your vehicle, which can be a characteristic trade-off when fitting a performance brake system or components. Whilst this noise typically originates from the braking components, many external factors like driving application, conditions, and vehicle components such as suspension and chassis can amplify these brake noises. Whilst every effort is made to mitigate and reduce brake noise to the lowest level possible, any additional noise is classed as acceptable and does not substantiate a product fault.
  • Images are for illustration purposes only
*ADR 31/01 Prescribes a fade and recovery test, hot performance where the car is braked from a maximum of 120 to 60 km/h 15 times with 45 seconds between each brake application. The vehicle must then pass an ordinary performance test and achieve 75% of the initial cold test result.
