Quaife ATB Helical LSD Differential for Honda Civic Type R (FK2 / FK8)

If you are looking for the best racing LSD for FK2 and FK8 Honda Civic Type R models, the Quaife Automatic Torque Biasing (ATB) Helical Limited Slip Differential (QDF20U) is the ultimate performance upgrade. Engineered as a direct drop-in replacement for the OEM factory unit, this differential completely transforms your front-wheel-drive platform by maximizing available traction and eliminating power-robbing wheelspin.

Unlike harsh, high-maintenance plate-style differentials, the gear-operated Quaife ATB never locks up. Instead, it continuously and smoothly biases engine torque away from the slipping inner tire toward the outer wheel with the most grip, allowing you to put down full power earlier out of every corner.

Why is the Quaife ATB Helical LSD the best choice for FK2 & FK8 Type R?

High-horsepower front-wheel-drive vehicles like the K20C1-powered Civic Type R demand a differential that can handle intense shock loads without corrupting steering feel. The Quaife helical gear setup provides distinct performance advantages over standard open or clutch-plate differentials:

Eliminates Torque Steer & Understeer: Reduces steering "snatch" under heavy acceleration, allowing for precise line control during aggressive cornering.
Progressive Torque Transfer: Automatically transfers power seamlessly without harsh engagement or set preload limits.
Maintenance-Free Operation: Uses internal gears instead of wearing friction plates, meaning no clutch discs to replace and no special friction-modifier fluids required.
Faster Acceleration & Lap Times: Drastically improves standing starts, drag strip launch traction, and exit speeds on road courses.
Motorsport-Proven Reliability: CAD-designed and CNC-machined in the UK from high-strength Corus steel billets to ISO 9001 standards.
