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.

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.

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.

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.
