OS Giken Limited Slip Differential Fluid - 80w-250 - 1 liter
(more info) The OS Giken Super Lock LSD Gear Oil 80W-250 1 Liter FR is the OS Giken's very own special blend of gear oil which does an excellent job of lubricating and protecting your Super Lock LSD from failure. Through use of this high quality liquid, your Super Lock LSD will last much longer if regular oil changes are performed.
OS Giken Limited Slip Differential Unit - E82 135i. E90/E92 335i (LSD)
(more info) A twin-turbo charged BMW such as the 135i or 335i needs traction to put that power to the ground. The stock differential of both the 135i and 335i only put power to one wheel -- this just won't cut it! Upgrading to a limited slip differential means power to BOTH wheels, for better lauch, acceleration, and track handling. We're excited to be carrying the OS Giken LSD unit in our performance catalog, as we've used their products on our own Championship winning E46 race cars.
Video: LSD makes all the diff-erence
With the 135i/335i LSD unit, they have incorporated revolutionary new ideas into the design (4 years in the making!) which uses an unprecedented number of friction plates (up to 28 total!) for better locking force, better engagement/disengagement, and less generated heat. The end result of their efforts is the OS Giken's OS Super Lock LSD which offers incredible durability and reliability on street and track driven BMWs. The use of highest quality materials, precise machining, forged gears and sound engineering makes this LSD durable and reliable enough for road racing performance (which we can personally vouch for!). Zero break-in required. Super smooth and quiet engagement, and 100% progressive locking capability. Professional installation is recommended.

We sell this part in a few different ways: 1) As long as you don't have a welded-in ring gear, TMS can install this unit in your car's original differential - You send us your diff and we install the limited slip unit and send the diff back. Some cars are being built with welded ring gear rather than a bolted-together unit.
2) We can send you a low mileage preowned diff with the limited slip installed - and we charge you a core charge. When you send us back your (non welded ring gear) stock diff we refund the core charge (currently $1600)
*** Please note that on mid year production (mid-'07) and newer 135i/335i's, we have found that the ring and pinion is welded in place, and cannot be unbolted to re-use with our limited slip "chunk". On these 335i's you must buy our LSD unit already installed into a differential (option #2), as your existing diff is not elligible for option #1 .

Rear Lower Link Arm Bushing - Inner - BMW Motorsport Race Rubber - E82, E9X
(more info) BMW Motorsport Group N rubber race bushings to replace the inner lower camber link arm bushings. These are a stiffer rubber version of the stock bushing - eliminating deflection and twist of the spring arm. This will result in a snappier feel and quicker response in the suspension and better handling. These bushings are great for track use - legal for some racing series, including Grand-Am - yet can also be used on a street driven car where extra ride harshness can be tolerated.
Sold as a pair of bushings for both sides of the vehicle.
