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.

High-Performance Brake Pads for stock brakes

If you want better brake pads for the street, consider Axxis.  Axxis pads are manufactured by Bendix Mintex (FMP Group Pty. Ltd.) in Australia.  Formerly marketed under the brand names PBR and Repco, they are now sold in the United States under the Axxis name.

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.  Stop washing brake dust off your wheels every few days!  These are by far our most popular street 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.  This is Zeckhausen Racing's favorite high performance street pad.

Centric Posi Quiet Semi-Metallic pads offer a high friction level across a wide temperature range. Very low dust, low noise w/OE designed composite shims to reduce pad vibration and squeal.  Easy on rotors.  Better performance than typical low-dust pads.  Give up the dust without giving up the performance.

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, only two of them 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 down below 2mm of remaining friction material, the rotor chews through a small plastic bump on the sensor and slices a wire in half.  This causes an open circuit, triggering a warning on your dash, either an idiot light or a "CHECK BRAKE LININGS" text message.  Once a warning has appeared, the sensor has been destroyed and must be replaced.

Each Centric brand replacement sensor comes with a short wire harness 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 new brake pad, with the small plastic bump facing TOWARD the rotor.

After replacing your pads and wear 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 brake warning, 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 X3 6-Speed?

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, 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.
