How to swap oem LSD from E30/E36 into E46 Non M Differential

As you all know BMW closed option for Limited slip differential in all non M models after year 2000. So if you have E46 for example, you don't have option for factory LSD unit if it is not an M3. This is very limitation factor of this car as there are quite powerful models such as 330i and 330d which would be much more fun to drive if they had Limited slip differential.

Aftermarket solutions are quite expensive, especially if you count in installation costs, new bearings, etc. Therefore we are well known among E46 owners for our affordable solution - Progressive LSD conversion set.

The Progressive LSD conversion kit is excellent option for street drivers who wish a bit more from their car, especially in snow. But what about those who wish more performance, but don't want to pay around $2000 for aftermarket LSD unit such as Kaaz, OS giken, Drexler...
