Wavetrac Differential - For 4WD DSG VAG 02E Transmission
- Calculated at Checkout
- Fits: Golf Mk6 R
- Audi A3 / S3 8P
- Octavia Mk2 4x4 / Golf Mk5 R32
The patented Wavetracåâ design automatically improves traction in low-grip conditions. This feature is an innovation and unlike any other torque biasing differential design.
- Superior Materials:
9310 steel gears run in case-hardened forged or billet steel bodies. ARPåâ fastening hardware used throughout.
- Maintenance Free:
The Wavetracåâ differential will perform a lifetime of service with no maintenance or rebuilds.
To best understand how the Wavetracåâ is truly different from the other gear differentials on the market, you first have to understand the primary problem that the Wavetrac solves.
The problem: Loss of drive during zero or near-zero axle-load conditions.
Zero axle-load is a condition that occurs during normal driving, but creates the most noticeable problems when driving in extreme conditions. Zero or near-zero axle-load is the condition that exists when there is "åno-load" applied through the drivetrain, when one drive wheel is nearly or completely lifted (often in aggressive cornering). It also occurs during the transition from engine driving a vehicle to engine braking and back, even with both drive wheels firmly on the ground.
Here"s how that loss of drive hurts you:
1) If you lift a wheel, all gear diffs except Wavetracåâ, will NOT power the other wheel.
2) During the transition from accel to decel, all gear diffs except Wavetracåâ, do nothing.
Why does this happen?
All gear LSDs (including Torsenåâ, Truetracåâ, Quaifeåâ, Peloquin, OBX, etc.) work in basically the same manner: they divide the drive torque between the two axles, applying drive to each side, up to the available grip of each tire. The amount of drive torque one wheel can get over the other is described as the bias ratio, a measure of the torque split across the axle.
Standard, open differentials have a bias ratio of 1:1. They can only apply as much drive torque as there is available traction at one wheel. When one wheel loses grip, the total available drive is lost as well (at a 1:1 ratio). All your power goes out the slipping wheel - along the path of least resistance.
Torque biasing differentials offer increased bias ratios over open differentials. For example, if a diff has a bias ratio of 2.5:1, then it can apply drive torque to the wheel with the most traction (gripping wheel) at 2.5 times the traction limit of the wheel with the least traction (slipping wheel). This is a significant improvement over an open diff most of the time.
The problem is that when one tire has LITTLE or NO grip (zero axle-load), the other wheel gets ZERO DRIVE, because (basic math here): 2.5 x 0 = 0.
Lift a wheel (or substantially unload a wheel) and you get zero axle-load on that side - that means that during the time the wheel is unloaded, the typical diff will NOT power the wheel that"s still on the ground. No matter how high the bias ratio, you get no power to the ground.
During the transition from accel to decel, where you have near zero torque on the axle, even if the wheels are on the ground, the typical diff is unable to begin applying drive torque until AFTER the zero torque condition is over. While this condition is generally short-lived, the fact that most diffs can do nothing during that time means that there will be a delay once the zero torque condition stops - creating a reaction time in the driveline.
Awesome GTI Delivery Information
Do we ship abroad ?
Yes we do, to anywhere in the world though remember the postage is often high when shipping anything bulky. Most bulky items we export will go by UKMail so you can track the package online and could reach america within 48 hours providing its in stock !
There are a few countries we do not ship to, some of these include: Thailand, Malaysia, Indonesia, Yugoslavia, Romania, Croatia, Hungary, Slovakia, Slovenia, Russia, Nigeria, Macedonia, Singapore, Bulgaria, Ukraine, Lebanon and Lithuania.
Why is postage on bulky items to some countries expensive compared to some other companies ?
For both yours and our safety we use well known couriers such as UKMail for shipping, then we know exactly where it is in the world at any time and we know its going to arrive safely. Shipping small items can be cheap, but items such as bodykits are expensive to ship - we have a very small margin on the postage fees merely to cover packaging. We can now ship using standard post on some items, however using all methods you may incur import charges when you receive the goods for which we cant be responsible for.
