Does anyone understand the differences between the Cusco LSDs?

RS - applied in same direction of initial torque through coil spring - lower torque rating for comfort and smoothness
MZ - applied in opposite direction through cone spring - high torque rating - immediate lockup

RS for daily driving (smooth)
MZ for special driving circumstances (harsh)

(I know nothing about LSD technology but that's what I am able to simplify for you in your decision)

If I was planning to drive the car daily, I'd probably buy the RS model (given the information provided on their website)

Thank you mate! And between 1 and 1.5 way?

By their description - i'd probably just go with the 1 way if you don't have issues with torque steer - it states that 1.5 is more for those who have significant torque steer issues.

1 way, 1.5 way and 2 way are how the different behaviors of LSDs are categorized.

1 way, the locking mechanism attempts to lock the differential under acceleration, but when decelerating it doesn't, so the differential essentially becomes open on deceleration.

2 way, the locking mechanism attempts to lock the differential under acceleration and under deceleration with the same amount of force.

1.5 way is sort of in between, the locking mechanism attempts to lock the differential under acceleration, and it attempts to lock the differential under deceleration but not with the same amount of force, maybe only like 30-50% of the force used while accelerating.

so probably the 1.5 way is the best option, right? what do you think? For the P10 only 1 and 1.5 way are available

I think you need to find out if this is for RS5F32A or RS5F32V gearbox.

Good call my friend

Helical LSD are in the works from MFactory. Similar to Quaife, but cheaper. They have been around for nine years and have lots and lots of proven records from a lot of High HP and high dollar Honda builds.

The UK Cusco dealer confirmed that they only sell lsd to replace the oem one, they don have lsd for the 32A box…what a pity

Mfactory is trying to make one for BOTH the VLSD and the open diff. gearboxes right now.

Here is a nifty Cuso guide from the manufacturers website.

I'll be running a 1 way RS set to 70% lock. The RS is the better of the 2 versions as it's smoother, and requires less maintenance.
From my research these are the best settings for a FWD motor, and you shouldn't get much clunking either.

For a 32a the Quaife unit is probably your best option.

I need one of these too.
