A box with a car part arrived today, usually this is a happy occasion, and that held true today.

The inner box with the MFactory logo gave a clue to the contents.

Designed for the Audi B5 S4, a helical limited slip differential.

I am impressed by the apparent value of the MFactory product.

In a later post I’ll get into the details that led to my decision to purchase the MFactory Helical LSD.

I don’t plan to install the LSD right away.

For now I’ll just admire the craftsmanship.
