[message]Wavetrac Europe is now stocking Wavetrac ATB LSD equipped axles! Wavetrac is the most technologically advanced ATB LSD available on the market, with the patent-protected features its design delivers performance and longevity like no other.
Most BMW axles from 07 onwards were manufactured with a friction welded ring gear and open differential. This can cause some headaches for installation concerning vehicle downtime while the factory differential/ring gear is separated by precisely machining the parts away.
Please Note:
*For the LSD Installation and Re-build (Stock Differential Needed*) option, you will be required to send us the entire differential casting which will then be rebuilt and returned to you
**If you cannot send us your differential, you may purchase the Wavetrac LSD Deposit which will be returned after inspection when you send us your non-damaged differential pumpkin. Please choose the Complete Rebuilt LSD (Deposit Required*) option at checkout and also add the deposit to your cart.
- Wavetrac ATB LSD
- ARP Ring Gear Bolts
- New, Genuine BMW Axle Seals
- Backlash Setup to OE Tolerances
- Precisely Machined Ring Gear
PLEASE NOTE
You will need to spec oil, for this application we advise for Motul Competition 75w140.
- If you lift a wheel, all gear diffs except Wavetrac®, will NOT power the other wheel.
- During the transition from accel to decel, all gear diffs except Wavetrac®, do nothing.
- The patented Wave hub improves driveability and performance during performance driving.
- The pinions in the Wavetrac run on patented Carbon Fibre bias plates in the housing. Whereas all other designs run the pinons directly on the steel housing. Overtime, with the metal on metal contact with other ATB designs friction can reduce and with this performance reduces. The carbon fibre bias plates in the Wavetrac create a consistent friction surface for the life of the differential for consistent performance.
- Its gear tooth forms are optimised for strength and improved oil film retention over competitive designs.
- gear package is smaller, reducing overall mass, yet is more durable since particular attention was paid to the tooth strength - optimised for high torque conditions.
- The internal gears are made from high strength 9310 alloy steel.
- The diff bodies are machined from case-hardened steel billet.
- Every Wavetrac® differential is built exclusively using high quality, high strength fasteners from ARP®, the world leader in fastener technology
- Direct comparison between Wavetrac & Quaife:
- Wavetrac maintains function throughout the corner
- Quaife performs like an open diff throughout the corner, sending power to the inside wheel and slowing momentum (you can see on the dash in that youtube video wheel speed increases but the vehicle speed does not)
- Wavetrac has a Lifetime, transferable warranty in all use cases including road, track, professional Motorsport, drag strip, rally etc
Here is an overview of the Advantages of a Wavetrac over plate LSDs
- Wavetrac requires zero maintenance. Plate LSDs require frequent servicing to maintain performance. As they are used the friction plates wear and performance drops off.
- Wavetrac does not increase Noise Vibration or Harshness. Noise Vibration & Harshness is comparatively higher and much more noticeable on a plate LSD.
- Wavetrac allows for chassis stiffness to be setup comparatively softer vs. a plate style LSD as you are not overcoming an locked axle on turn-in. This improves overall mechanical grip, allowing for more setup variation.
- Wavetrac never locks harshly, improving longevity of driveline components i.e. driveshafts.
- Wavetrac has a Lifetime, transferable warranty in all use cases including road, track, professional Motorsport, drag strip, rally etc whereas plate differentials typically come with no warranty or a very limited warranty
