Wavetrac Differential BMW M2, M2C F1X M3, M4 F8X M5 F9X 210 e-diff [re-map required]

Wavetrac? diffs are state-of-the-art helical gear differentials designed, developed, and manufactured in the USA by Autotech Driveline. The Wavetrac? Differential is the only torque biasing differential on the market with patented technology that mitigates wheelspin when an unloaded wheel condition arises. During zero axle load conditions, the Wavetrac cam device acts to create internal load, maintaining drive on the gripping wheel instead of acting like an open diff (and going nowhere!). Super strong 9310 alloy steel gears are enclosed in case-hardened steel bodies, held together with ARP? fasteners. All Wavetrac? differentials include a transferable, Limited Lifetime Warranty.

The factory M-Active differential is considered by some as an improvement over the Viscous LSD in the previous E46/E9X M3 models but for those who have experienced a quality aftermarket differential, they know there is a lot of performance and driveability left on the table.?

Wavetrac's LSD for the F8X M2/M3/M4, F1X M5/M6 & F9X M5 solves differential related reliability, driveability and performance problems.?

Common complaints from customers and dealers has always been that the factory differential is unpredictable when it works and once it overheats... just feels like an open differential.?

For those who are looking for a lifetime warrantied upgrade which will eliminate the erratic operation of the factory diff, replacing it with the signature smooth operation of the Wavetrac, allowing you to confidently eek out all of your cars performance...?with performance that is undeniably better than all other ATB LSD designs, the Wavetrac is the perfect solution for fast-road users, track day junkies and even those who use their ///M cars for standing start racing like VMAX.?

As with all other Wavetrac LSDs these are lifetime warrantied, even for pure motorsport use.?
