Precisely engineered, converging \/ diverging wave profiles are placed on one side gear and its mating preload hub. As the two side gears rotate relative to each other, each wave surface climbs the other, causing them to move apart. This imparts an increased normal force through the side gears, increasing the bias ratio as a function of load. This increase occurs automatically only when conditions find it necessary, and it 'reverts' back to its nominal bias ratio quickly and seamlessly, maintaining optimal drivability and performance at all times. It's like having two differentials in one: you get the benefit of a higher bias ratio when needed without detriment to the car's handling.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/www.vwvortex.com\/artman\/uploads\/picture-2_002.jpg\" alt=\"\" border=\"0\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInterchangeable Friction Plates Provide Controlled Bias\u003c\/strong\u003e\u003cbr\u003e Here's something else you won't find in any other design:\u003cbr\u003e The Wavetrac® differentials behavior can be altered in the field to suit your needs. It comes standard with carbon-fiber bias plates for the best all around performance. Interchangeable plates using materials with different friction coefficients to fine-tune the bias ratio are sold separately.\u003cbr\u003e These friction plates provide a mechanism to tune the response of the differential as a function of applied torque load. The applied torque load manifests itself as an axial load from the differential pinions into the housing. This axial force is then considered a normal force into the friction plate, and as a function of the effective coefficient of friction, will provide a resistive torque to the rotational motion of the differential pinions. The resistive torque will add to the resistance of relative rotation of all components within the differential. The resistive force, however, is non-uniform since it is a function of the axial load from the differential pinions. The unbalance of the resistive torque will manifest as non-uniform energy absorption within the differential causing a bias ratio.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/www.vwvortex.com\/artman\/uploads\/picture-3_002.jpg\" alt=\"\" border=\"0\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSuperior Design, Materials, and Construction\u003c\/strong\u003e\u003cbr\u003e Designed from a clean sheet, the new Wavetrac® Differential brings current gear technology to the market. Internally, its gear tooth forms are optimized for strength and improved oil film retention over competitive designs. Our gear package is smaller, reducing overall mass, yet is more durable. Attention was also paid to the side gear\/axle interface, putting as much material thickness as possible in this critical area - most important when power levels get high.\u003cbr\u003e Each Wavetrac® Differential is crafted from the highest quality materials available. The internal gears are made from high strength 9310 alloy steel. The diff bodies are machined from case hardened steel billet. To complete the package, every Wavetrac® differential is built using high quality, high strength fasteners exclusively from ARP®, the world leader in fastener technology.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e A Note About 20T vs. 25T 02E DSG Transmissions:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe differentials in Volkswagen 02E series dual clutch transmissions (DSG) feature a toothed ring on the body that is engaged by a claw when shifted to \"par,\" acting as the parking trans-brake does in automatic transmissions. There have been two styles of this toothed ring used in the DSG over the years. The early (coarse) ones have 20 teeth, while the late (fine) ones have 25 teeth. Before fitting the Wavetrac differential, verify that it has the matching toothed ring as your original differential. Do not install anything (bearings, ring gear, etc.) on the Wavetrac before checking this!\u003c\/p\u003e\n\u003c\/div\u003e","brand":"034Motorsport","offers":[{"title":"Default Title","offer_id":67804106162480,"sku":"WAV-10.309.188WK","price":1526.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0677\/7582\/4176\/files\/wavetrac-02e-limited-slip-differential-lsd-front-awd-8p-8j-audi-a3-tt-mkv-mkvi-volkswagen-r32-golfr-10-309-188wk.jpg?v=1789665244","url":"https:\/\/es-performance.com\/en-us\/products\/034motorsport-wavetrac-02e-limited-slip-differential-mkv-gti-jetta-8p-8j-audi-a3-tt-awd-s-tronic-dsg-20t-ring","provider":"Eurosport Performance","version":"1.0","type":"link"}
