'TW3' Works as well as it looks.
To create the perfect rotor there needs to be a balance of available friction surface combined with a limited number of slots. Too many slots will leave less friction surface, therefore reducing brake efficiency. This will also cause an excess of pad resin deposits across the friction surface which if left to build-up can lead to 'hot spots'. Resin build-up can become so severe that it can cause brake shudder, pedal pulsation and sever vibration through the steering wheel. It most cases these symptoms are mistaken for rotor runout or a warped disc.
Sparta's engineers have studied the ramifications of pad resin build up on the rotor face and the effects it has on the braking system. These studies led to the creation of our patented TW3 (Thermal Window 3) slot design.
By machining our TW3 slot pattern into the face of the rotor, the pad resin spread becomes more even across the friction surface, reducing the chances of hot spots and pad deposits. To further minimize rotor stress, the TW3 slots start and end over the pillars in our patented DCF96 vent pattern, preventing excessive material thickness variations that can lead to cracking in extreme thermal environments.
'DCF96' The new standard for
Our patented Dynamic Continuous Flow (DCF96) brake disc vane design has proven to be superior to other designs on the market, addressing many weaknesses found in traditional vane designs. Traditional discs feature vane patterns that are either straight or curved. When heat is applied to a traditional disc, the material will expand both radially and linearly. The linear expansion results in the disc's friction surfaces ballooning outwards, which can cause up to a 30% loss of pad contact with the rotor. Another symptom of this linear expansion manifests as a shudder in the steering wheel or pedal under light braking pressure, commonly attributed to disc thickness variation (DTV).
The DCF96 vane design reduces and helps eliminate this linear expansion. The secret is in the vane design, which features 96 strategically placed pillars and posts for advanced heat distribution and DTV minimization. As a disc rotates, ambient air flows through the disc's ventilation channel. The air then circulates around the pillars, helping dissipate the heat and expel it away from the disc. The pockets in the DCF96 design conduct heat away from the friction surface and into the pillars, reducing the disc's linear expansion. The DCF96 vane design is multi-directional, meaning that they can be installed on either side of the vehicle without affecting their cooling efficiency, as opposed to traditional curved vane patterns that lose cooling efficiency if spun in the wrong direction.
