Wavetrac ATB Limited-Slip Differential (LSD) AUDI 02Q
8J TT 2WD – Front Wheel Drive

Simply put: Wavetrac is the only gear-type limited-slip differential on the market that doesn't lose drive even if one drive axle lightens or loses load. This situation often arises during aggressive driving, when driving over curbs on a track, or on very slippery surfaces – more often than many might think.

How does Wavetrac affect performance?

Let's take an example of a traditional gear-type locker (OEM, Quaife, MF, OBX, Truetrac, Torsen, etc.). You're driving on a track, and in a corner, the inner wheel hits a curb and momentarily lightens. This is normal in track driving. The problem is that during that brief moment, the other wheel doesn't get any drive – the engine's power isn't transferred to the road.

Gear-type lockers require load on both axles to function. Therefore, in a situation where one wheel lightens, the drive to the other wheel is momentarily interrupted. The result is that on a track or during aggressive driving, power is only intermittently transferred to the wheel with traction.

With Wavetrac, the situation is different. Its patented cam mechanism prevents loss of drive, even if one wheel lightens. The mechanism can create the necessary load inside the differential to compensate for the lost traction, allowing power to be directed to the wheel with traction. The result is smoother power delivery in corners, more predictable handling, and overall a faster car.

Other Benefits

• Patented Carbon Fiber Bias Plate for Satellite Gears
  In most gear-type lockers, the satellite gears rotate directly against the housing, causing friction to change with use and the locker's efficiency to decrease. Wavetrac's carbon fiber plates maintain consistent performance throughout their lifespan.

• Patented Wave Profile Design
  Eliminates drive issues at near zero load found in other ATB-type differentials.

• ARP bolts throughout
  Excellent strength and reliability for heavy-duty use.

• 9310 Steel Gears
  Installed in a machined or forged steel case for maximum durability.

• Designed and Manufactured in the USA

Wavetrac – Smooth is Fast

Wavetrac is ideally suited for high-performance street cars that are also used on the track. It is extremely durable, yet virtually unnoticeable to the driver and the car's traction control systems during normal driving.

On the track or during spirited street driving, it transmits power to both wheels without the handling issues caused by traditional clutch-type lockers – for example, the increased understeer or "push" is avoided.

Wavetrac outperforms other gear-type lockers because it does not lose drive when one axle lightens – a situation that happens surprisingly often in reality.

One of Wavetrac's most underrated features is its extremely smooth power delivery at the limit of traction. The patented design makes power transfer predictable and smooth exactly when it's needed most: in the middle of a corner at the traction limit or on exit when maintaining speed with the throttle.

In these situations, the difference is clearly felt by the driver. Wavetrac makes the car faster because it allows you to drive with more confidence.
Smooth is fast.
