Hi lads, just wandering if anyone is running a kaaz plate lsd, or helical one, wandering wat you think of it and do you rate it, i will be doing track days and i will be doing drag cheers lads.
 
Great unit, keep in mind there is a slight hidden cost with Kaaz as you must use there Diff oil every time you change your fluid or service the gearbox. I would feel very confident installing one of those in my car, the price of the MFactory unit is also very attractive.

Is this going in a B16b box or a box without LSD?
 
which do you have the solid or basic, i know man thats the problem its between the mfactory one of kaaz, i like quite hardcore driving and will always go for performance over comfort lol
 
I run the Spoon, pretty much the same, its hardcore for the road but well worth it, on track its awsome. I use MTF3, some say I could run other stuff to help the clunking & wheel drag but who cares.
 
I ran one of these for a year on road, i liked it very much you can feel it more than the helical one. The lock up when powering down pulls you in to corners really well and you can literally plant the throttle much earlier on corner exit.
Small tight bends is a struggle though and they carpark reverse parking is a pain cos you look like an idiot taking a much larger turning circle.
Maitenance was a pain - you need Kaaz LSD oil and costing around 20 pounds a go it is expensive ****, Motul, REdline and others don;t work cos it's so noisy and impossible to change gears. Cusco fluid is compatible though.

Braking is much more controlled too.

I am back to helical type and more comfortable and maintenance free. If you are a hardcore driver then sure go for the Kaaz.

The general consensus is that if you drive your car on the street at all and/or do Drag Racing, then you are best going for a Helical LSD, especially on a FWD (As Helical LSD's don't "lock", it does not affect your steering response). There is also the fact that they don't need to be maintained, just run your regular transmission fluid.

If, however, you car spends most of its life on a circuit, then the Plate LSD is the way to go. Be warned though, it takes time to learn how to drive your car properly with the Plate LSD. Even semi-experienced drivers who have never driven with a Plate LSD before will sometimes find beginners who are running a Helical LSD faster than them ;)

I think it really depends on where you are living too. In Hong Kong where temperatures seldom if EVER drop before 10deg C - you can get away with KAAZ fluids. In other parts of the world that get colder - UK, some parts of North America, I found the KAAZ fluid to be horrible in the cold.

Redline MT90/MTL with a bottle of Ford Friction modifier works great in that sense. Torco is good too. If you're mainly in the streets and insist on the plate diff - you get can also get away with using Honda MTF and some friction modifier too.

Some LSDs have a very high initial lock and they will click and pop no matter what fluids are used. Cusco/ OS Giken do not require a high initial lock to attain the level of performance expected from a plate LSD. This is due to their clever designs.... our plate diff does not require a high initial lock either... :secret::p

Cant make up my mind lol, im a pretty agressive driver, you think the plate wont be anygood for drag.
 
plate is perfectly fine for drag. :)

I went 13.4x @ 102mph with a plate diff :secret:
 
did you say the mf are more of just as aggressive as the solid kaaz diffs, ps love the new logo lol
 
You can use the Plate LSD for drag, as long as you don't make mega power as the plates are not designed to withstand extreme torque.

What about ATS metal LSD? are they high or low initial lock type?
is it true that if the LSD has higher total effective frictional area/coefficient (via more plates/groove/large size plate/surface treatment/etc) they can get away with lower initial lock for smoother engagement without sacrificing lock response/performance?
is this high/low initial lock mechanism set via the cam angle?

The D20 metal LSD from ATS has a pretty aggressive lock from what I have been told. I have no personal experience with ATS diffs and have only used their clutches.

what most drivers tend to desire is an aggressive initial lock so it responds quickly and immediately to their inputs. OS Giken, Cusco and we use springs to initiate the immediacy of the initial lock under load but when one is merely navigating around the pits or parking, it doesn't engage abruptly.

The cam angle is responsible for setting the initial lock. There are normally two settings 45degrees and 35degrees, the latter being more aggressive and is not normally used for road courses - only for gymkhana/autocross but this is of course dependent on the driver/setting of the car.

High initial lock can also cause stress on other components such as the axles, wheel bearings/hubs. The most common symptom of high initial lock are torn axle boots and in some extreme cases, broken axles or even a broken diff housing.
