Lsd for C51 gearbox

[thefalls]

So its time to get an LSD for the C51 gearbox that comes in the Corolla Axio GT.
From research i have been able to find out that the Cseries 50/51/52/56 gearboxes share the same LSD. But the C150/151/160 dont share the same LSd as they have different bolt pattern.

So the car is going to be daily driven and occasional spirited driving but not tracked.

What would you guys advise helical or clutch type?

I know that the helical is fit and forget type with zero maintenance whereas the clutch types need regular transmission oil change and at some point the clutch packs will need changing.

In terms of performance which is better ?

And yeah,is this good?
