LSD 617 C15: Precision Engineering for Optimal Performance

The LSD 617 C15 is a high-performance Limited-Slip Differential (LSD) gear designed to enhance your driving experience, especially in motorsport applications. Unlike standard open differentials that are commonly found in everyday vehicles, this advanced LSD system ensures that power is effectively transferred to the road, no matter the conditions. Whether you're navigating tight corners or tackling challenging terrains, the LSD 617 C15 is engineered to keep all driving wheels engaged for maximum traction.

How the LSD 617 C15 Outperforms Factory Components

The LSD 617 C15 significantly improves upon factory components by limiting the free-wheeling of wheels that may be slipping or airborne. This capability is crucial for maintaining power delivery to the ground. With a controlled locking effect on each driving wheel, drivers can experience enhanced grip and stability, leading to improved handling and performance.

Key Features of the LSD 617 C15

  • Consistent Initial Lock Setting: The LSD features a more uniform distribution of friction across the plates compared to traditional systems.
  • Innovative Inner-Coil Spring Design: This design allows for lower initial lock settings while achieving a similar response, enhancing overall performance.
  • Durable Friction Plate Contact: Springs maintain even contact with the friction plates, prolonging their lifespan and preventing surface deformation.
  • Customizable Cam Ramps: Choose between two cam ramps on the pressure plate for tailored tuning options.
  • Adjustable Initial Torque Settings: Easily adjust settings by modifying the positioning and number of coil springs.
  • Consistent Actuation: The vector of force applied by the pressure plate mirrors the initial lock springs, ensuring reliable LSD actuation.
  • Minimized Chattering: The RS Type design reduces plate chattering with consistent pressure across the friction plate surface.

Benefits of the LSD 617 C15

  • Lower maintenance requirements for racing-grade LSD units.
  • Immediate actuation response from the initial lock setting to the maximum preset lock rate.
  • Ideal for lower-powered, compact cars competing in various motorsport events.
  • Perfect for standing-start drag racing and autocross with quick-trigger starts.

Fitment

The LSD 617 C15 is specifically designed for the Suzuki Swift Sport ZC31S, ensuring a perfect fit and optimal performance for this vehicle.

Customer Feedback

Many customers have praised the LSD 617 C15 for its remarkable performance in competitive settings. One user noted, "The difference was night and day! The car felt so much more stable during cornering, and I could feel the power being distributed evenly across the wheels." Another driver shared, "This LSD has transformed my racing experience. The immediate response when I accelerate is fantastic, making it easier to handle tight turns." With such positive feedback, it's clear that the LSD 617 C15 is a game-changer for motorsport enthusiasts.
