The Quaife ATB Helical LSD Differential is a limited-slip differential designed for the Ford Focus MK2 ST with the M66 manual transmission.The LSD (Limited Slip Differential) is a device that helps distribute torque between the two drive wheels of a vehicle. In the case of the Quaife ATB Helical LSD, it uses a helical gear design to provide torque biasing, which means it can transfer torque to the wheel with more traction during cornering or when one wheel loses grip.
This differential is specifically designed for the Ford Focus MK2 ST with the M66 manual transmission, which is the standard transmission for this model. It is a direct replacement for the factory open differential and does not require any modifications to the transmission or drivetrain.
The Quaife ATB Helical LSD Differential offers improved traction and handling performance, especially in situations where one wheel may lose traction, such as during aggressive cornering or when driving on slippery surfaces. It helps to reduce wheel spin and improve power delivery to the ground, resulting in better acceleration and stability.
Overall, the Quaife ATB Helical LSD Differential is a popular upgrade for Ford Focus MK2 ST owners looking to improve the performance and handling characteristics of their vehicle.

These are my favorite socks
Color: Blue & Green, Size: Medium
Theses socks are so comfortable perfect size and thickness theses were the only socks I took on a 2 week Ireland trip with me.
These are a great value for your money and they look so cute on, I could not find any socks in Ireland that were as soft and have the durability that these have.
I highly recommend! I am a sock lover also and picket about texture.

This item is vibrant in color, but I could tell right away, It wasn’t going to be durable and indestructible like the description said. My dog had it destroyed in less than a minute.
