Why Upgrade your Brakes?

Big brakes give your car greater resistance to fade by absorbing and shedding heat more efficiently.  Racers upgrade because stock brakes were designed for a single stop from high speed, not repeated slow-downs with little time in between to cool off.  For fade resistance, size really does matter.  On the street, fixed-mount, multi-piston calipers give a firmer pedal and quicker reaction time in panic stops.  As little as 0.2 second reduction in reaction time can translate into 21 feet of stopping distance at 70 mph.  Reaction time is not as important to racers who can compensate by braking earlier.  But on the street, in an unexpected stop, quicker reaction time can save your life.  You don't need to be a racer to benefit from brake upgrades.

If you track or autocross your car regularly, your stock brakes are probably not up to the task.  You can start off with better brake fluid, more aggressive brake pads, cooling ducts, and stainless braided brake lines.  But as you progress from novice to intermediate skill level and beyond, carrying more speed into the braking zones, your track events will become characterized by boiling brake fluid, sinking brake pedal, and pad fade.  Losing confidence in your brakes takes the fun out of a track event.  Big brake upgrades allow you to dive deeper into the braking zone and brake harder than you ever thought possible.

 

Big Brake Kits

StopTech big brake kits are designed to maintain optimum front to rear brake torque balance, resulting in the shortest possible stopping distance and total compatibility with ABS and modern electronic stability control systems.  The fixed-mount, multi-piston calipers yield a firmer pedal feel and quicker reaction time in panic stops.  Every StopTech application is thoroughly track tested as part of the development process.  [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 and gold add $200 per caliper pair.  Slotted rotors are standard.  Drilled rotors may be substituted for $100/pair.  Drilled rotors are for street use and not appropriate for the race track.

Under development!  We are an exclusive dealer for StopTech's new Carbon Ceramic Brake System (CCBS).  Most StopTech 4-wheel brake kits may be optionally equipped with these exotic lightweight carbon ceramic rotors.  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 almost 2 years, including track, street, and extreme winter conditions.  The system has performed beyond our expectations.  Call for details and availability.

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.

Premium

SportStop

 

Better than stock rotors!  Centric Premium rotors are identical in dimensions and internal vane design to the factory originals.  During assembly, rotors are straddle cut for the most accurate machining, then double disc ground for optimum parallelism, minimal runout, and near zero thickness variation.  A non-directional finish is applied for better initial pad bedding.  All surfaces, including the hat, are machined and non-swept surfaces are electrostatically coated with a durable, black finish (unless noted otherwise below) for corrosion protection and good looks.  Finally, all rotors are computer mill balanced to incredibly tight tolerances.  You won't find a better replacement rotor anywhere.  Click here for more details. 

Power Slot rotors are available for most applications, offering the advantages of Centric Premium rotors, with the addition of slotting for higher bite and friction.

StopTech SportStop rotors are available for many applications, offering the advantages of Centric Premium rotors, with the addition of slotting and/or drilling for higher bite and friction.

How to choose between them?  Slotted rotors provide additional bite and maintain consistent friction level over the life of your pads.  These are ideal for aggressive street and even road racing applications.  Slotted and drilled rotors offer even more bite and stunning looks, but should be used on the street and not for racing.  If you want slotted or slotted and drilled rotors and there is no pricing listed below, send an inquiry to orders@zeckhausen.com and we can let you know if they are available.  Or check our on-line store, which has many more vehicle listings:  STORE

Make sure you install your rotors properly.  See: How to Properly Install Plain, Slotted or Drilled Rotors

(Centric Parts is the parent company of Power Slot and StopTech .  Power Slot and StopTech rotors start as Centric blanks and are machined in the USA by Centric Parts on computer controlled milling machines.)

To obtain information about any rotor, click on the part number (if a link is present) for details, including rotor drawings, replacement thickness, critical dimensions, and weight.  The term "floating" does not mean two-piece, floating rotor.  It is Centric's terminology for a rotor that can be removed without also removing the vehicle's wheel bearings or hubs.

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 TÜV 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.

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 °F, after which it falls off slowly.  Frequently used in the rear in conjunction with Ferodo DS3000 in front.

R-$95

63-360-0340

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.

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.
