The 2002tii BMW 3.91 slip differential LSD is a high-performance upgrade for your 1981-1983 BMW E21 3 Series, specifically for the 320i and 320is models. This differential is not only a replacement for your stock unit but also an upgrade, offering enhanced traction, improved handling, and smoother power delivery.
The 3.91 ratio of this LSD (Limited Slip Differential) ensures optimal power distribution between the drive wheels, reducing wheel spin and improving acceleration under various driving conditions. This is particularly beneficial during high-speed cornering or when launching from a standstill, ensuring your vehicle maintains a consistent and stable grip on the road.
The slip differential feature of this LSD allows for some wheel slip during cornering, helping the vehicle to turn more aggressively and with less understeer. This is achieved through a set of clutches that engage and disengage as required, distributing torque between the wheels based on their traction levels.
The LSD unit is designed to be a direct replacement for your existing differential, requiring no modifications to your vehicle's drivetrain. It is manufactured using high-quality materials and precision engineering, ensuring long-lasting durability and reliability.
Installing this LSD differential in your 2002 BMW E21 3 Series can significantly enhance your driving experience, providing improved performance and handling, as well as increased safety on the road.
