RacingBrake Big Brake Kit Advantages

RacingBrake aluminum caliper big brake kits decrease stopping distance, eliminate brake fade, stiffen the brake pedal, and provide better brake modulation. Through our patented two-piece rotor design, we keep the brake system cool and increase braking power, longevity, and performance. Most of our racing customers demand strong and consistent brake torque under "extreme" braking conditions, durable system components, and an affordable price. RacingBrake focuses on these expectations and delivers a system that suits racers' braking needs and includes everything needed for a complete installation.

When researching upgrading to an aluminum caliper big brake kit, consider the following overall costs:

• What will the initial investment and installation cost be?
• Do you need any other hardware that does not come with the kit?
• What will be the operating and maintenance cost to replace brake rotors and pads?

Initial Investment

A major part of a big brake kit is the initial investment. We price our brake kits competitively while maintaining the quality and performance our customers expect. Below are a few examples of how we compare to Stoptech and Brembo.

Rotors

RacingBrake two-piece rotors are directional (different for left and right sides), heat treated for added strength, and use RB's patented center mount design and convergent vane design, which increase airflow and makes the disc cooler. Electrodeposition Paint (EDP) is used to coat the aluminum hat, which is light weight and highly resistant to rust and corrosion. Hardware is a simple 2-piece component design (stud & nut) and is self locking to prevent the use of springs, glue, or clips.

Maintenance: Rotor Rings
RB rotor rings are most well known for their durability – they last event after event without needing replacement. If you need replacement rings, our rotor rings cost only a fraction of the competitions'.

** RacingBrake's surface mount rotors are designed to fit Stoptech and Brembo rotor hats. They are built with our patented convergent vane design for better cooling. The discs are also alloyed and heat treated for extra resistance to warping and cracking. Learn more...

One-piece rotors are on a select few of our big brake kit applications. One piece rotors cost significantly less than two-piece rotors and are perfect for daily driving.

Pads

Our popular 4-piston caliper kits use standard FMSI pad #D647 (same pad as 2006+ Subaru WRX) instead of special, high priced pads.

RB ET Series Brake Pads
From daily driver to dedicated tracking racing enthusiast, our ET-series brake pads provide a selection of various compounds that makes them easy to choose and use at an affordable cost.

• ET500: $89
• ET700: $133
• ET800: $174
• ET900: $186

Calipers

RacingBrake calipers are made from forged aluminum and precisely machined to every detail. They are lightweight, stiff, and coated with liquid paint which is more resistant to chipping or scratching than powder coating. Stock calipers - aluminum (Brembo) or cast iron (06-08 WRX) are mass-produced and are usually made through a casting or extrusion process which is not as dense and strong in structure as forging.

The pistons in the RB4000, RB400 and RB600 calipers are made of stainless steel, versus Brembo and other manufacturers' aluminum pistons. Stainless steel transfers about 1/10 the heat of aluminum, resulting in significantly less heat transfer from the pads to the brake fluid. Stainless steel is also more rigid and higher in strength than aluminum. Being that stainless steel has a comparable melting point (2700°F) to brake pads' steel backing plates, the pistons will never melt to the pad backing plates. Aluminum pistons (1220°F) can melt to brake pad backing plates under extreme high speed braking.

Brake pad pins and banjo connections were designed for easier installation and allows quick replacement of brake pads, as compared to calipers that must be completely removed just to replace brake pads.

RB calipers have double seals – An inner seal for brake fluid and an outer seal for fluid and dust. Stock calipers typically use dust boots (instead of seals), which can be easily torn.

RacingBrake calipers are mounted to the adaptor with two high strength alloy steel bolts in a radial direction (top mount) - from the caliper down to the adaptor. Stock Brembo and cast iron fixed piston calipers are mounted in an axial direction (side mount), from the spindle to caliper. A top mount caliper is more rigid than a side mount caliper.

Adaptors

The adaptors are made out of high-strength 7070-T6 aluminum alloy which minimizes any bending or flexing when the calipers engage.

Fitment

Each of our brake kits has a fitment diagram for you to check to see if our system will fit your wheels. Our kits can have better axial clearance than competitors' kits due to our patented center mount design, which sets the rotor farther inboard. In addition, our kits and don't require you to buy expensive larger wheels, wheel spacers, or longer wheel studs.
