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.
