For competition type driving we strongly recommend our full engine and transmission mount kit, but for more moderate use you may change the transmission mounts only. The purpose of these mounts is to reduce transmission/gearshift pattern movement and minimize the chance of selecting the wrong gear.

Korman 50% and 75% Limited Slip Differential Conversions

If you race, autocross, rally, do BMW driving schools, or otherwise tend to push your car to the limit, let us convert your 25% limited slip differential to 50% or 75%  limited slip. Wheel spin is reduced or eliminated, improving track times significantly. Additionally, the reduction in internal slippage lowers lubricant temperatures, helping prolong bearing life. The conversion requires special machining at our facility, making it necessary for you to ship your differential to us for modification.  Your salesperson can help you decide which percentage is right for you.

Quaife Automatic Torque-Biasing Limited Slip Units

Already used in Formula 1, IMSA, SCCA and Pro Rally applications, Quaife Automatic Torque Biasing Limited Slip Units are now available for your BMW. Quaife units utilize a gear driven mechanical process to direct power at an infinitely variable rate (as opposed to a fixed 25%, 40% or 75% rate) to the wheel with the most traction. Unlike the more complicated and fragile Torsen design and the BMW OEM clutch pack limited slip units which tend to transfer power abruptly, the Quaife units are simple and rugged in design and provide a very smooth power transfer between the two driven wheels. Quaife units have proven to make as much a one second per mile difference in lap times on road courses. We can provide you with the unit for your own installation, or install it here in our facility. (These units are sold on an outright basis making them an ideal option for cars which did not come equipped with a limited slip differential from the factory)
