3-Series (E90/E91/E92/E93)  (2005-2011)

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.  Fixed-mount, multi-piston calipers produce a firmer pedal feel and quicker reaction time than stock brakes in panic stops.  Every StopTech application is track tested and fine-tuned as part of the development process.  StopTech is the only major big brake kit manufacturer to use application-specific caliper piston sizing.  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 at no additional cost and add about 30 days to the delivery date.  Slotted or drilled rotors are available.  Drilled rotors are recommended for the street, while slotted rotors may be used for street or racing.  For vehicles driven where salt or chemicals are used to melt snow and ice, optional zinc plated rotors are recommended.  Add $100 to the price of any kit for zinc plating.

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.  Click here for our Trophy brakes announcement in our latest magazine ad.

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: 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.

Centric Premium rotors are identical in dimensions 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 for corrosion protection and good looks.  Finally, rotors are computer mill balanced to incredibly tight tolerances.  You won't find better replacement rotors anywhere.  Click here for video with more product details. 

Centric Premium High Carbon rotors utilize an advanced metallurgy that reduces pad squeal. The proprietary Molybdenum and Chromium alloy resists rotor cracking during heavy track use and increases the friction level, improving brake performance and stopping power. Increased Chromium and Carbon content is also more resistant to surface oxidation.  For some applications, directional internal cooling vanes are used for improved cooling over the straight-vane factory rotors.

StopTech Sport rotors offer the advantages of Centric Premium High Carbon rotors, with the addition of slotting and/or drilling for higher bite and friction and more consistent brake pad performance over the pad lifetime.

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:  STORE

Make sure you install your rotors properly.  See: How to Properly Install Plain, Slotted or Drilled Rotors

(Centric Parts is the parent company of StopTech .  StopTech rotors start as Centric High Carbon blanks and are machined in the USA 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.

Problems shifting your new BMW 3-Series?

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, click here.

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.
