Cusco RS 1.5, Quaife or OSG!?
Guess ill just get whichever I can get cheapest, they all seem to be pretty highly rated.

I was reading this thread and did some further research. Of the three:
OSGI (Shipping & Returns)
Cusco (HOME - Cusco LSD)
Quaife (Quaife Limited Slip Differential)

Only the Quaife offers any warranty at all. (limited lifetime)

Still your call, but something to consider.

Hmm yeah that is something that makes it stand out from the crowd. But which one puts power to the ground the best for TT, and also is comfortable to drive daily?

I would go with whatever is cheapest and easiest to get serviced in your area. They all make a big improvement in mechanical grip. They real deal as mentioned in the thread about on braking is the tires or tyres you choose to run.

I went with the CUSCO 1.5 RS from Revzone who set it up and installed it for me. It is clunky and loud doing parking maneuvers but fine everywhere else and is great on the track.

Yeah RevZone are the guys who offered the Cusco to me.

Anyone have the Kaaz Super Q? The clutch plates are WPC treated so it is supposed to be super smooth and super quiet

Driftomodachi · 09-08-2017, 02:00 PM

Reason OS Giken is so bad *** is because it has MORE CLUTCH PLATES than Cusco so it runs smoother and lasts longer. Reason I like Kaaz super q is because it is like a Cusco but the plates are WPC COATED and have very low friction surface so it is QUIET and also lasts longer. It is also about $400 less than the OS Giken. Quaife will suck on ice or if the car gets airborne because it is dependent on ONE wheel slipping so it won't be good for drifting only road racing.

shadow85 · 09-08-2017, 05:45 PM

Ok. So im regards to the quaife, alot of the roads around where I travel are not 100% flat, some areas can feel bumpy. So when I drive hard on these roads I can sometimes feel my Z going slightly airborne, maybe only very briefly.

Would that situation be bad for a quaife LSD? I don't want to be gunning it hard and then lose control over a small hump or dip on the road.

jchammond · 09-08-2017, 08:50 PM

Probably isn't many, that would still have traction while airborne.

gomer_110 · 09-09-2017, 09:23 PM

The Cusco 1.5 way is definitely loud and clunky. Definitely would not recommend it for a street driven car. For a track toy/competition car it is great option though.

Interesting, but some others claim it not to be too loud.

The Quaife is fine,,,unless you're going off road or turning at bad angles (up & down)...you got to really get it in an awkward position to "teeter" up one rear wheel.
I need to jack up one side of mine to confirm it...but there was only one instance when i drove off a steep angle from concrete to grass that it appeared to not be pulling w/both rear wheels.
Other than that-i have perfectly even rear tire wear.

I was going to get the Cusco 1.5. Daelen at MA Motorsports talked me out of it, and into the OS Giken. Said the OS Giken is quieter then the Cusco and a little better on the street. That plus he gave me a great price on the OS Giken.

Pretty much exactly what I've heard. At this point though I'm not changing the LSD out again. Given the car rarely sees street duty these days and primarily sees autox events its streetability isn't high on my list of concerns.

BobbyLight · 09-22-2017, 11:58 AM

So when you say the clutch types are clunky on super tight stuff, does that depend on speed or just the angle of the turn itself?

For example, on something like the tail of the dragon would you get clunk with the cusco or OSG?
