Wavetrac – Smooth is Fast

Wavetrac is the only gear-type limited-slip differential on the market that does not lose traction even if one driveshaft lightens or loses its load. Such situations arise, for example, in aggressive driving, track driving in corners, or on very slippery surfaces. They occur much more often than many might realize.

At this stage, we will not delve into torque distribution ratios or how torque-distributing differentials technically work. Let's focus on how Wavetrac affects car performance.

How does Wavetrac improve performance?

Imagine a situation with a traditional gear-type differential, such as OEM, Quaife, MF, OBX, Truetrac, or Torsen. You are driving on a track day, and in a corner, the car's inside wheel hits a curb and momentarily lightens. This is completely normal in track driving.

The problem arises because, during that brief moment, the load on the inner wheel disappears. In this case, the other wheel does not receive drive – the engine's power is not effectively transferred to the road.

Gear-type differentials require load on both drive shafts to function. As a result, on the track or during aggressive driving, a standard gear-type limited-slip differential can only intermittently transmit power to the gripping wheel whenever the other wheel lightens.

With Wavetrac, the situation is different.

Wavetrac's patented cam mechanism prevents loss of drive in situations where the inner wheel lightens. The mechanism can create a load within the differential that replaces the lost load precisely when it occurs. This load can then be directed to the gripping wheel.

The result is a smoother and more consistent power transfer throughout the corner. The car behaves more predictably and is faster overall.

Other Benefits

• Patented Carbon Fibre Bias Plate design for satellite gears
  In other gear-type LSD differentials, the satellite gears operate directly against the housing. As a result, friction characteristics change with use, which can impair the differential's operation and efficiency during its lifespan. Wavetrac's patented carbon fiber Bias Plate design allows for consistent and smooth performance throughout its lifespan.
• Patented Wave Profile design
  Eliminates drivability issues related to zero and very low load situations that occur in other gear-type ATB differentials.
• ARP bolts throughout
  High-quality ARP bolts ensure excellent strength and reliability even in demanding performance use.
• 9310 steel gears
  High-strength 9310 steel gears operate in a machined or forged steel housing, providing exceptional durability for the structure.
• Designed and manufactured in the USA

Wavetrac – Smooth is Fast

Wavetrac is an ideal solution for powerful street cars that are also driven on the track. It is extremely durable but remains practically unnoticed in normal street driving by both the driver and the car's traction control and stability systems.

On the track or during spirited street driving, Wavetrac effectively transfers power to both wheels without the drivability issues caused by traditional clutch-type differentials. Wavetrac does not have a tendency to cause the car to push or increase understeer, as traditional clutch-based limited-slip differentials can.

Wavetrac outperforms other gear-type differentials precisely in what is its key strength: it does not lose traction in situations where one driveshaft lightens or loses its load – and such situations occur much more often in real driving than one might imagine.

One of Wavetrac's most underrated advantages is its extremely smooth and controlled power transfer at the limit of grip.

The patented design allows for predictable and smooth power addition precisely when it is most needed – in situations where the car's performance is at the absolute limit of grip. For example, in the middle of a corner, when the car is at the limit of grip and balance is maintained with the throttle, or in a situation where a corner has been entered a little too fast and the throttle can be quickly reapplied to maintain exit speed.

These situations are partly subjectively experienced by the driver, but the advantage offered by Wavetrac is clearly felt behind the wheel.

Wavetrac makes the car faster because it allows for more confident and trustworthy driving.
