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 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 give you a
firmer pedal feel and a 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 only and are not appropriate for the race track.
New! We are an exclusive dealer
for StopTech's exciting new Carbon Ceramic Brake System (CCBS).
Most StopTech 4-wheel brake kits may be optionally equipped with these exotic and
lightweight carbon ceramic rotors. Significantly lighter than cast
iron, these rotors can shave as much as 80 pounds of rotating weight
from your vehicle, dramatically improving your car's handling, acceleration and
suspension compliance. Better heat capacity, resistance to cracking
and oxidation, and improved response in heavy rain than existing ceramic
brake options, such as the Porsche PCCB system. These rotors also last far longer than anything
else out there. Call us for details. Will

How to Choose the Right StopTech Brake Kit for your 350Z
The 13" front brake kit may be combined with the 12.9" rear to create a 4-wheel big brake upgrade
and both 14" front kits (4-piston or 6-piston) may be combined with either
the 12.9" or the 14" rear kit. With so many choices (three front and five
4-wheel kit combinations) which should you pick? That depends on how
you use the car and what your goals are for the upgrade.
Improvement in street performance at the
lowest possible price
The 13" front kit gets you the advantage of
the widest possible wheel fitment, including many 17" sizes. You get
almost as much improvement in pedal feel as the 14" front kits at a much
lower price. You can always add the 12.9" rear kit later. The
14" 4-piston rear kit is not compatible with the 13" front kit.
Best looking on the street
The 14" 6-piston front kit, combined with the
14" 4-piston rear kit is the most impressive looking, especially behind
fancy wheels with an open spoke design. The ST-60 6-piston calipers
are gigantic and really stand out. For $600 less, you can combine the
14" 4-piston front kit with the 14" 4-piston rear kit. Some people
actually prefer the look of four identical calipers.
Racing, Open Track Events, High-Speed Driving
Schools
At the track, either 14" front kit will keep
rotor temperatures lower than the 13" kit and much lower than the stock
brakes. These lower temperatures reduce pad and rotor wear and help
prevent pad and fluid fade. The 6-piston 14" kit does not offer any
performance advantages over the 4-piston 14" kit, but the much larger pads
in the ST-60 calipers will last longer under race conditions. If
aesthetics are playing a part in this upgrade, then the 6-piston front kit
may be what you want, even if it is overkill.
TThe 12.9"
rear kit is the appropriate choice for racing, since there is a wide selection of
race pads
available for the ST-22 2-piston caliper. The 14" ST-45 rear kit
has limited pad choices. For most
other vehicles, Zeckhausen Racing does not consider a rear big brake kit to
be required for track use. But the postage stamp sized stock
rear pads on the 350Z will burn up in a few sessions, even when using race
friction. This is one platform where a rear kit is necessary for track
use.

Premium Rotors
|
|
SportStop Rotors
|
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.
(Note: Centric is the parent
company of StopTech and PowerSlot. All StopTech SportStop and Power Slot
rotors start as Centric Premium blanks and are machined in-house on computer
controlled milling machines.)
StopTech SportStop rotors are available for
many applications, offering all the advantages of Centric Premium rotors, with
the addition of slotting and/or drilling. 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 prefer 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.
Make sure you install them properly. See:
How to Properly Install Plain,
Slotted or Drilled Rotors
To obtain more information about any rotor, you
may click on the part number (if a link is present) to see more details,
including rotor drawings, recommended replacement thickness, critical
dimensions, and weight. Note: The term "floating" in the rotor
description does not mean two-piece, floating rotor. It is Centric's terminology for a
rotor that can be removed without also removing the car's wheel bearings or hubs.

Stainless Steel Braided Brake Lines |
Improve pedal feel
by replacing stock rubber lines with 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 manipulate the throttle to
match engine revs to transmission speed.
StopTech's 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 other 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.
When installing a front big brake kit,
Zeckhausen Racing strongly 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 enough lines for
both sides of your vehicle. To order, click here:
and then locate your vehicle
along the left side of the on-line store page. Or, feel free to call us at
(800)222-8893 for help selecting the proper parts.

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. This is
Zeckhausen Racing's favorite high performance street pad.

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.

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.

Drivers with competition tires and heavy, powerful cars can experience fluid fade and destruction of
caliper dust boots and piston seals, even after the installation of a big
brake kit.
These titanium inserts are installed behind the pads, dramatically reducing heat transfer
to the calipers. This helps prevent dust boots from vaporizing and
reduces the
temperature of the brake fluid. They are especially effective when the
pads have worn by 50 percent or more, since worn pads provide less thermal insulation between the rotors and calipers.

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, use the Tire Decision Guide
by Tire Rack. Select the appropriate model year, then click the Go
button. You'll be asked a couple of questions which will help narrow down
your tire choices to the select few which most closely match your driving needs.
From Maximum Performance tires to All Season tires to Snow Tires, Tire Rack has
it all. The Tire Decision Guide takes the guesswork out of buying tires
for your car.
