Why do you want an OS Giken Super Lock LSD?
Improved acceleration, traction and stability. OS Giken manufactures one of the worlds best Clutch-Type LSDs available. Fully progressive with 100% locking capability, no break-in, extremely long life and nearly completely-silent. This is the ultimate way to put power to the ground for those that have a more aggressive driving style, or who are setting up a competitive car.
Not only do you get the advantages of acceleration, but the clutch type LSDs are available with different locking profiles for different driving styles. This makes them great for the high speeds of road racing and track use.
OS Giken's Super Lock is not just for racing, its also found its way into BMW, Porsche and AMG street cars around the world for its exceptional street mannerisms and quiet performance. All of this extra traction can also have improvements in low grip conditions like snow or rain.
  • Exceptionally long life
  • Maximizes traction and minimizes wheel spin
  • Excellent for drifting, road racing or street driving
  • Super quiet even though it uses clutch plates
  • Made in Japan
  • Used in many high-profile championship wining vehicles of the past decade
What does a Clutch-type Limited Slip differential like an OS Giken do?
Through clutch plates with internal mechanisms, a clutch type LSD applies load to both rear wheels and aids in powering the car forward when the wheels are turning at different rates, or when acceleration off the line. As with powerful cars, taking advantage off all the traction available from a standing start and in the corners is important, however- clutch type LSDs for BMWs are setup with some locking affect on deceleration as well: when entering a corner, this load and balance of traction helps to increase the stability of the car when coming in at high speed improving confidence and safety. This leads to faster cornering potential. This is what Japanese companies refer to as a 1.5 way LSD, and is excellent for everything from daily drivers to all out competition vehicles.

VAC Tips:
-We have run a OS Giken Super Lock HARD in our daily driven and often tracked 135i with absolute success. We have had a stock unit, Wavetrac and Quafe ATB in this car and we all agree that the Super Lock is the unit for the person looking for max performance with no compromises in the NVH dept. Clutch type units really put the power down.
-We have sold dozens of these to other 135i and 335i owners with absolutely NO problems.
-The Super Lock is the best choice for those looking to get a diff that is a bit more serious than the much loved Quaife ATB.
-Additionally we have installed Super Locks in platforms other than E8x/E9x and they always perform flawlessly.
