Big Brake Kits

StopTech big brake kits are designed for each vehicle with optimum front-to-rear brake torque balance, resulting in the shortest possible stopping distance of any aftermarket brake upgrade and total compatibility with ABS and electronic stability control.  The fixed-mount, multi-piston calipers produce a firmer pedal feel and quicker reaction time than stock brakes in panic stops.  Every StopTech application is thoroughly track tested and fine-tuned as part of the development process.  See: Track testing write-up

StopTech big brake kits are available with red or black calipers standard.  Silver, gold, blue or yellow calipers are available and add 30 days to the delivery date.  Silver is a no-cost upgrade.  Blue, yellow or gold add $200 per caliper pair.  Slotted rotors standard.  Drilled rotors available for $100/pair.  Drilled rotors are recommended for the street, while slotted rotors may be used for street or racing.

New!  StopTech's ultra-high end Trophy Sport and Trophy Race brake systems are now available.  20% lighter calipers and extreme heat resistant natural anodized finish for heavy racing applications.  Click here for our Trophy brakes announcement in our latest magazine ad.

Under development!  We will be an exclusive dealer for StopTech's new Carbon Ceramic Brake System (CCBS).  Significantly lighter than cast iron, these shave up to 60 pounds of rotating weight from your brakes, dramatically improving handling, acceleration and ride.  Better heat capacity, resistance to cracking and oxidation, and responsiveness in heavy rain than existing OEM ceramic options, such as Porsche's PCCB system.  Not delicate, like C6 Corvette ZR1 brakes.  We've been conducting durability and usability testing for over 2 years, including track, street, and extreme winter conditions.  The system has performed beyond our expectations.  Call for details or check back for availability.

Stainless Steel Braided Brake Lines

Improve pedal feel by replacing stock rubber lines with StopTech stainless steel braided Teflon lines.  Stock lines expand under pressure, contributing to spongy pedal feel.  StopTech lines reduce pedal travel and firm up pedal feel, allowing precise brake modulation.  Useful for drivers who "heel-toe" downshift, providing a more stable platform from which to modulate the throttle to match engine revs to transmission speed.

StopTech lines are covered with stainless steel weave to provide support and protect from abrasion and impact.  The stainless braid is molded inside a layer of clear plastic to protect the lines from the environment and to protect your car's suspension and delicate sensor wires from the "hacksaw effect" possible with uncoated steel braided brake lines.  These lines are DOT compliant and may be legally used on the highway, unlike lines sold for "off-road use only."  StopTech lines have been tested and approved by the TUV for sale in Germany.

100 percent tested!  Every StopTech line is tested at 4,500 psi before it is packed and shipped.  Most manufacturers perform no pressure testing.  Some test random samples from their assembly line or test to lower pressures.  No other company tests every single brake line.

When installing a front big brake kit, Zeckhausen Racing recommends upgrading your rear brake lines.  4-wheel big brake kits come with front and rear steel braided lines, so no additional purchase is necessary.

Each brake line kit includes parts for both sides of your vehicle.  To order, click here: and locate your vehicle along the left side of the store page.  Or, feel free to call us at (800)222-8893 x1 for help selecting the proper parts.

Save your expensive rotors!

Factory Audi front brake pads have metal retaining pins embedded in the friction material.  In theory, these pins are supposed to be soft enough to wear with the pads.  In fact, they dig into your expensive Audi rotors and can ruin them, even if your pads are only 50% worn and BEFORE your pad wear sensor is triggered.

Stock Audi RS4 Pads - 50% Worn

The stock pads only start out with about 11mm of thickness (not including the metal backing plate).  It doesn't take many miles for the rivets to become exposed and your front rotors to start looking like a phonograph record.

In order to preserve your stock rotors and dramatically reduce the brake dust turning your wheels black, Zeckhausen Racing recommends Centric Posi Quiet brake pads. 

Centric pads are direct replacements and require no modifications, unlike other aftermarket pads for the Audi.  These pads include electronic wear sensors and factory compatible harness.

For higher performance applications, when dust isn't a primary concern, we recommend the new StopTech Street Performance pads.

StopTech Street Performance brake pads are StopTech's newest formulation, offering an unusual combination of good bite, low noise, and extremely wide temperature range, making them ideal as "dual use" street to medium track pads. These are the standard pads included with StopTech big brakes and are now available for many OEM applications.  These are Zeckhausen Racing's preferred high performance street pads.

Ferodo DS2500 Club Race pads can be used on the street and for light to medium track duty.  Good cold bite, but can be noisy.  Proper bedding can help reduce this noise.  Less compressible than other pads, giving it excellent pedal feel and good modulation.  The average friction level of about 0.50 remains constant at any speed and at temperatures up to 1,000 degrees F, after which it falls off slowly.  Frequently used in the rear in conjunction with Ferodo DS3000 in front.

F-$185

63-360-1029

Two sets required

Ferodo DS3000 Race pads have very high coefficient of friction of about 0.62, a flat torque output over its operating temperature range and very good modulation characteristics.  Frequently used in the front of front engine cars in conjunction with Ferodo DS2500 in the rear.  Not recommended for street use.

Hawk DTC-60 is a member of the "Dynamic Torque Control" race pad family with similar characteristics to DTC-70, but less initial bite, slightly lower friction and an optimal temperature range starting 100 degrees F lower.  An ideal rear pad, when used with DTC-70 in front, for racers who prefer split friction levels.  May be used in front on lower horsepower cars or on cold days when DTC-70 can't be heated sufficiently.  Relatively low rotor and pad wear.

F-$368

63-470-1029

Hawk DTC-70 is the most serious member of the "Dynamic Torque Control" race pad family, with an average level of friction among the highest available and an incredibly linear pressure to torque relationship. The result gives the driver an unparalleled ability to modulate brake torque at the limit of tire adhesion, while keeping pedal effort low.  Relatively low rotor and pad wear for such an aggressive pad.

F-$392

63-480-1029

Porterfield R4 Full Race pads are extremely rotor friendly, with consistent modulation throughout their temperature range.  The Carbon Kevlar material warms up quickly, making them good for short events and cold weather.  Excellent for novice through advanced intermediate drivers.  Not for street use.

Performance, All-Season, and Winter Tires

Besides brakes, tires are the most important component in determining stopping distance.  It's literally where the rubber meets the road.  Selecting the right tire for your driving conditions can make a tremendous difference.  For example, if you live in Florida or southern California and are driving on all-season tires, you are leaving huge performance gains on the table!  A good set of summer-only performance tires can literally transform the handling and braking capabilities of your car.  In fact, if your goal is to minimize stopping distance, you're better off going to Tire Rack's web site and buying tires first, before spending any money here on better brakes!

For the best selection and prices, we recommend Tire Rack.  From Maximum Performance tires to All Season tires to Snow Tires, Tire Rack has it all.  Tire Rack also offers wheel and tire packages and can even tell you which wheels will clear your StopTech big brake upgrade.  Click the Tire Rack icon below for your best deal on wheels and tires.
