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:

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.

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

Axxis Deluxe Advanced street
pads (formerly called Deluxe Plus) are ideal if you are looking for a low dust pad that is quiet and rotor friendly, yet has
enough fade resistance for
performance cars. These ceramic-enhanced organic pads work well up to 716
°F, similar to OEM pads.

Axxis ULT street pads
pads (formerly called Axxis Ultimate) use a Kevlar®
and ceramic formula for enhanced performance. They produce maximum
friction when cold, yet have tremendous fade resistance up to 932 °F. The
coefficient of friction is high enough to produce a noticeable reduction in
pedal effort. Fine for autocross or your first
track event, assuming street tires and a low horsepower car.

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°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.

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.

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.

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.
