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 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.

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:

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.

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.

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.

PFC
01 Race pads have very high
average torque output, rising over its operating
temperature range, and a MOT of 2000 degrees F. Excellent bite, low
rotor wear, and average pad wear. Novice drivers may find this pad
challenging to modulate. Pad of choice for top race teams and our
favorite due to overwhelming positive feedback and few complaints of judder. Frequently used in the front of front engine
cars with PFC 97 in the rear.

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.

Replacement Brake Pad Wear Sensors |
|
BMW uses brake pad wear sensors to
monitor the condition of your brake pads. Although your BMW has eight
brake pads, on most models, only two pads are monitored for wear - the driver's side
front inboard pad and the passenger's side rear inboard pad.
Thus, you should only order one front and one rear
sensor. When a monitored pad has worn below 2mm, the rotor chews through a plastic bump on
the sensor and slices a wire. This causes an open circuit,
triggering a warning on your dash, either an idiot light or "CHECK BRAKE
LININGS" message. Once a warning has appeared, the sensor has
been destroyed and must be replaced.
Each Centric brand replacement sensor comes
with a wire and connector that clips into your BMW's main wiring harness.
The other end (shown below in the enlarged gray box) clips into a slot at
the top of your brake pad, with the plastic bump facing TOWARD the
rotor.
E46 M3 sensor shown - your BMW model's
sensor may have a different appearance
After replacing pads and sensors,
the dash warning will still be illuminated. However, you do not need
to go to your BMW dealer to have the warning message reset. To reset
the warning on most models, turn the ignition key to the run position, but do not
start the car. After about one minute, the brake pad warning will
reset.

Problems shifting your BMW Z4 M Roadster or
Coupe smoothly?
Many models of BMWs with
5-speed or 6-speed manual transmissions have a Clutch Delay Valve (CDV)
installed by the factory. This valve is the culprit behind the jerky
shifting that makes your BMW hard to drive, even if you have been driving a
standard transmission all your life. When replaced with the Zeckhausen
Racing modified CDV, your clutch is suddenly transformed into the smooth, easy
to modulate clutch that should have been delivered from the factory as standard.
Extend the life of your clutch and increase the enjoyment of your BMW driving
experience today!
For
full details of this modification, including history, theory of operation,
installation instructions, and a free CDV exchange service by mail,

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.
