So far I've found it to be a nice improvement over the standard diff. Most of my driving is motorway based and so the engine is revving slightly higher than standard but nothing major.
I'm running 245 wide rear tyres and the car does feel a lot more planted but it can still brake traction if you want it too.
Overall i'd rate it highly for daily driving
Thanks for that Enda.

Can I ask is it OEM and if so what car it originally came from?
It is OEM. The 3.45 small case diff housing came from an M42 engined 318is I think but never actually saw the car. I bought if from England.
The LSD unit itself Valdas had in stock at the time.
