- Solve wheel spin and rear end instability with the Wavetrac LSD
The Wavetrac LSD solves one of the biggest problems with the otherwise incredible BMW 135i, the standard open differential. The open differential limits traction and grip by sending power to the wheel with the least grip when traction is lost, when this happens the traction control aggressively intervenes and limits power, this slows down acceleration and when traction control is off it makes the rear end very unstable.
With the Wavetrac LSD upgrade fitted power is sent seamlessly to the wheel with the most grip, maximising traction and allowing you to control the car much more easily and consistently, even when you want to powerslide it.
This particular customer is preparing his BMW 135i for track days and chose the Wavetrac LSD over the Quaife thanks to its patented design features which allow it to outperform the Quaife in multiple areas by solving a couple of design flaws.
The first design flaw is that the Quaife, and similarly designed ATB LSDs perform like a standard open differential when axle load is lost, this happens when cornering heavily (suspension unloading), wheel lift or wheel slip. When this happens the Quaife and other ATB LSDs send power to the freely slipping wheel, just like the standard open differential. To solve this the Wavetrac uses a patented "wave hub" assembly which generates internal load which allows it to continue to work in those conditions, improving performance and driveability.
The other problem the Wavetrac solves is a reduction in performance over time. Where the Quaife and other ATB LSDs run the pinons directly on the housings, which over time reduces friction inside the LSD, the Wavetrac uses lifetime warrantied carbon fibre bias plates. These bias plates create a consistent friction surface for the entire life (read lifetime warranty!) of the differential, meaning the Wavetrac will perform just as goon on mile 1 as it will in 100,000 miles!
We have Wavetrac LSDs available for many makes and models, stocked here in the UK and we can ship worldwide or install at our Southampton facility.

I thought this was a demo video to show how much better it is lol
We have plenty of other videos on the channel giving a technical explanation, you can also head to www.wavetrac.eu > Technical to view the technical information.
@@RegalAutosport nice! Thanks
How does compare to the M Performance LSD in terms of quality and reliability? Thanks
Quality & Reliability = Wavetrac has a lifetime transferable warranty which means you can remove it and sell it to someone else and they also get the Wavetrac warranty.
Performance wise the Wavetrac will also be much more consistent as the M Performance LSD is a plate differential which means as the differential is used the plates wear, this reduces the locking potential of the differential and over time it will feel like an open differential unless the LSD is removed and parts replaced.
You used to install plate style LSDs to overcome the problems with a Quaife and other ATB LSDs which is that when axle load is lost, they perform like an open differential. With installing a plate LSD though you also had to accept that performance will drop off over time with use and higher NVH (noise, vibration and harshness). With the Wavetrac, these problems are solved!
Regal Autosport thank you!
No problem, let us know if you have any others ☺️
Do you guys can tell me a price here for a f21?
This is on an AT diff right? From what i understand the MT diffs are welded shut on the 135i
From 07 BMW begun friction welding the axles (apart from E9X M3). There is a small transition period whereby some are bolted and some welded.
The only way to know for sure if your axle is welded or not is to open the cover and look. We do stock a range of exchange axles and keep all of the Wavetrac LSDs in-stock for a fast and efficient customer experience.
