clutch plate vs. helical LSD

Any preference and why?

Any preference and why?

It all depends on how you use your vehicle. Generally:

Street
If you’re looking for a differential to help get the power down and prevent one tire fires, a Torsen or helical differential is a great option for street use.

Track
For track use, something more aggressive tends to be a better option, such as a one-way or 1.5-way clutch type LSD.

Drift/Rally
For drifting or rally driving, occasionally a two-way LSD may be the best option, as it’s more desirable in these scenarios for wheel speeds to remain relatively equal.

Most on the n54/e9X are helical but that is because most are driven on the street and not tracked. There is also less maintenance and clutch plates can wear out or can potentially not be able to handle the power.

I've had both. I'm firmly in the clutch plate variety. My car has a 40:10 and power delivery is hugely different than with the helical. I like having a little on decel too.

What kind of speed difference between left and right tires may one expect from a quaife-type differential vs clutch type LSD on power?
