Pyramid of upgrades


Suprisingly one of the least effective upgrades (within a reasonable budget) is power. What? That’s correct. Sure if you have an unlimited budget and can turn that wheezing 6 cylinder into a 1000 HP monster you’ll pick up some significant time (and a few pairs of soiled underpants) but for the rest of us without a money tree there are more effective upgrades. 

Now read that list again. I’ve listed it in order of effectiveness. You’ll notice that YOU are at the top of that list. Remember you’re the first round draft pick for your own track team, so invest your money in yourself first! 

So lets get to it:

No More Fade

No more fade = short, repeatable stops, turn after turn.

Rotor Metallurgy

Braking converts the energy of the moving car (kinetic energy) to slow the Audi vehicle down. The rotor must have the ability to absorb these large amounts of heat and be able to transfer the heat to the air moving through the vanes separating the disc surfaces. The rotors are made from deep core castings with high carbon and copper content, from a casting much larger than the finished rotor. The casting is then machined to a smaller size where the material composition deep inside the casting is consistent and homogenous. The combination of the casting process and unique alloy composition results in better heat absorption and conduction.

Vane Design

STaSIS brakes use either 48 or 252 vanes, depending on application, to draw air from the center of the rotor outward. These vanes work like a pump to move cool air through the center of the rotor, taking the heat away from the rotor and cooling it before the next heavy braking zone.

Combining the highly advanced iron alloy with the efficient aerofoil vane design allows the rotor to absorb large amounts of energy (heat), then eliminate heat quickly so that it is not transferred to the calipers, pads, and brake fluid, providing consistent stoping power over multiple applications for your Audi vehicle.

No Warping

Properly designed two-piece floating rotors = quiet, warp-free performance.

Benefit of Two-Piece Floating Rotors

When brakes are applied and the moving energy (kinetic energy) is converted into heat, the rotor expands radially and axially (diameter and thickness). STaSIS uses a floating rotor that can thermally grow separate from the hat. This design is superior to a one-piece rotor—when a one-piece rotor is overheated, it gets much hotter than the hat and they expand at different rates, causing warpage or cracking.

STaSIS Floating Rotor Construction

Racers have long used floating rotor technology, but the rotors found on racecars move freely on the floating pin drive connecting the hat to the rotor, causing noise. To eliminate the rattling race rotor for our luxury Audi street car customers, we have engineered a unique noise-reducing methodology that eliminates noise but still allows for thermal expansion without running out of "float."

Quicker Reaction Time

Lowered caliper and line flex + small piston retraction = short, consistent pedal travel.

Caliper Design

STaSIS calipers are cast from one piece of aluminum. This single casting design with the cross bridges cast in place creates a very stiff unit and very little compliance during braking. Less compliance means less pedal travel because the brake fluid is only applying force to the pistons, not bending the caliper. The STaSIS design applies the maximum amount of force to the brake pads in the Audi vehicle.

Caliper Piston Seals

STaSIS brakes use ultra-high-resilience piston seals, with proprietary retraction angle shape, minimizing piston travel distance for less dead pedal travel and resulting in better pedal feel in the Audi vehicle.

Caliper Weather Seals

STaSIS brakes use long-life weather seals captured in a proprietary internal piston bore groove to provide consistent performance when moving between street applications and track applications for your Audi vehicle. The ability to retain (rather than burn off) the weather seals is unique in the industry. STaSIS brake systems are the only brakes to use weather seals in professional competition, providing longer life in full-time race duty.

Stainless Steel Braided Brake Lines

Braided lines reduce the amount of flexure in the line when the brake fluid is pressurized. Like minimizing compliance in the caliper, doing so with the brake lines provides for a firm pedal again and again. The maximum force is applied to the brake pads, not to flexing the lines.

Improved Pedal Feel

Improved pedal feel = superior driver confidence.

Minimize Compliance, Fade and Pedal Travel

Many of the benefits described above apply to improving pedal feel. Low compliance in the caliper and brake lines ensures a firm pedal. Reduced fade and ultra-high-resilience piston seals promote short and repeatable pedal travel, turn after turn.

Segmented Crescent Slots

Crescent slots provide gas relief and pad cleaning while minimizing the pedal pulsations normally associated with straight-slotted rotors or cracking issues common with cross-drilled rotors.

Less Weight

Less weight = shorter stopping distance, quicker acceleration, improved steering feel and handling

The combination of aluminum monobloc calipers, small annulus iron rotors mated to lightweight aluminum hats, and lightweight, high-strength hardware results in a STaSIS brake system weighing much less than the stock brakes in your Audi vehicle.

The weight reduction in rotating unsprung mass measures up to 14 pounds per corner, and can be felt and measured in acceleration and deceleration performance. Removing unsprung mass is the holy grail in performance. Every 1 pound reduction in unsprung mass (wheels, tires, moving suspension parts) is equivalent to 1.5 pounds in sprung mass (car chassis/body, passengers, etc).

Lower Long-Term Maintenance Costs

Cutting-edge design = durable, low-cost systems.

Longer Lasting Rotors

STaSIS brake systems cost more up front, but over time, lower replacement costs means lower long term cost over the life of the Audi vehicle.  Because our rotors can run cooler due to better heat transfer, and because they can resist warping and cracking due to floating disc design, our rotors last considerably longer than factory rotors. We have seen rotors last up to five times as long as an factory rotor after being put through heavy track use.

Advanced Rotor Metallurgy

STaSIS rotors are comprised of a proprietary alloy offering stellar performance and great longevity. This advanced metallurgy allows for uniform heat distribution, structural integrity at high thermal loads, and greater resistance to thermal shock.

Advanced Piston Seal Technology

The internal weather seal design of STaSIS calipers protects the seal from the high heat generated from high-performance braking. This design coupled with the ultra-high-resilience material ensures long-term use and protects the pistons from dirt and grime.

Differential Piston Design Promotes Even Pad Wear

STaSIS monobloc calipers are designed with four or six differential pistons. Differential piston sizing compensates for mechanical end loading by applying greater force to the trailing edge of the pad. Even pressure applied to the pad protects from tapered wear and lengthens the life of the pad. Under aggressive braking, factory calipers can flex, causing pad taper that dramatically reduces the life of the pad. The STaSIS system eliminates pad taper due to caliper flex.

Compatibility and Ease of Installation

Excellent design = compatibility with Audi factory equipment and easy installation

STaSIS brake kits are complete bolt-on systems, no fabrication required. 

Engineered Design

STaSIS meticulously evaluates every Audi vehicle to determine the proper piston and rotor sizing to provide the driver maximum control under braking conditions. The Audi stock braking system applies a larger force to the front brakes relative to the rear brakes because the front wheels do a larger amount of work during braking. The difference in front to rear braking force is called bias. STaSIS brake kits maintain brake bias close to the Audi factory components so that optimum braking is achieved and the anti-lock braking system (ABS) and traction control system continue to function properly.

Complete Kits

STaSIS brake kits are complete with all brackets, lines and mounting hardware so that your kit can be installed quickly and easily into your Audi vehicle.

Track Use

STaSIS brakes are built for use on the street. Use on the track requires an appropriate supply of fresh brake pads and brake fluid designed for track use and other maintenance. STaSIS recommends that any driver considering track use become familiar with competition brake maintenance procedures.

Turbulator or non-turbulator?

Looking to identify if you have Turbulator or Non-Turbulator rotors?  Here's how!

IMPORTANT - To identify if these are the Turbulator or Non turbulator style rotor, measure the air-gap between the rotor surfaces and the metal disc thickness.

There were TWO versions of this rotor size.  Please verify which one you are ordering.

The Non-Turbulator DIV2175X535C48 - 14mm Air Gap - 9mm surface thickness 19mm Air Gap - 6.5mm - 7mm surface thickness.
The Turbulator DIV2202X602C48 - 19mm Air Gap - 6.5mm - 7mm surface thickness

These discs are direct replacements for your Stasis/Alcon BBK.  They will bolt on and are directional so you must order a Left and a Right. We also suggest replacing your brake pads andhardware when buying new rings.  Replacing the pads at this times guarantees better rotor life and better break-in than using old pads.

Advantage Extreme discs have been engineered to produce optimum bite, thermal stability and durability in an exceptionally high strength to low weight design.  This hasbeen achieved by combining a special Alcon developed iron alloy disc with an aerospace specification alloy bell.

Identifying your STaSIS hardware kit

When replacing your STaSIS(tm)/Alcon rotors, you should also replace the hardware at the same time.  Stasis had several versions of the hardware so you will need to identify which hardware you have in order to order the correct kit.  Hardware replacement is generally good practice for any brake system, street and especially track.  However, in the case of the STaSIS assemblies, the disc springs have a tendency to flatten with age.  The fine threads in the nut & bolt are often compromised upon removal due to corrosion

Rotor directional vanes.

Rotors/Discs may be unidirectional but for high performance many have directional vanes and slots.  Alcon rotors/discs will come with a Left and Right designation.  If you cannot find that or are using a different rotor, his should help you correctly install the disc on your car.

Internal vanes should lean towards the rear of the car.  This helps pump more cooling air through the disc.  Slots should lean towards the front of the car however the internal vanes take precedence and should drive the direction of the disc, even if that means the slots are not optimal.
