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

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.

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.
