Performance Gearing: from 0 to amazing, custom-built for performance and power

 

 

Limited Slip Final Drive

BMW offers lots of performance upgrades, but does not offer a limited slip differential. Don't let anyone tell you that traction control is an adequate substitute for the performance that comes from having a limited slip final drive.  Traction control is an electronic override, not a mechanically-engineered solution. Get every last bit of driving performance from your existing horsepower and torque.  Our engineering artists will help create the driving experience you deserve.  We now offer this upgrade for all BMW models.

  • Our limited slip final drive is complete and ready to bolt in with no modifications
  • Performance Gearing stands behind its limited slip differentials with a best-in-the-business 3 year warranty

"the new diff is absolutely magnificent. acceleration is much better , the spacing of 2,3,4 now makes driving a pleasure. especially the 2 to 3, car is flying!! 6th gear turns about 3600 at 90 mph, so highway driving is fine as well. the power on engagement is very smooth. 40-60 deg turns in second are astonishing. a little bit of tire chirp, and the car just explodes out of corners. phenomenal. much better than torque-bias diff, no comparison. power off seems also actually very good. i tried to unsettle the car by stuffing 2 gear at 40 mph, no brakes, and dumping the clutch. tires chirp, but the rear does not come out. thank you for this excellent product, it puts smile on my face every time i drive."
