Hi guys

Does anyone know what type of LSD the rear diff from a V5 type r is?

On the track I have the problem that when the inner rear wheel is lifted, it is spinning and no power is transmitted.

Can I do anything to solve this? (other LSD?)

Thanks.

Its a plated R180 diff, who makes it I dont know but that sounds normal, wheel off the ground, no power to it, thats what they are meant to do.

On the contrary Tony, a plated diff ought [ ought ] to drive with one wheel lifted. A viscous will slip. lt sounds like the plated has lost its tension after many road miles [ and corners ] and needs resetting. Unfortunately with the diff being in Switzerland there is limited [ sorry ! ] help l can offer.

Of course it may not be the original plated LSD too, there's a thought.

But we rebuild and reset them all the time.

Sorry to hijack guys but does the type r have a centre and front LSD aswell? What about the newage 6 speed running gear?

Well; a type R STI will have dccd in the centre . WRX type R has it as an option rather than original fit.

Front LSD is also an option on 5 speed cars and is usually viscous as Plated needs to be very loose or the car gets very torque-steer-y. Some cars have a helical option fitted and they are generally better.

6 speed parts; front viscous or helical Lsd's will not fit [ easily ] into a 5 speed case. 6 speed have a front viscous [ Suretrack ] up til 2005 and then helical after. They all seem to work well in a 6 speed car, whereas doing the same to a 5 speed seems fraught with complications.

So the 6 speed sti has a front, centre and rear lsd?

Just curious as when i was under a widetrack blobeye when it was up on ramps, you could turn one back wheel and the other side would move with you but this didnt happen with the front.

Are the quaife lsd's a good upgrade?

It's a bit complicated making a statement about front LSD's on 6 speeder,with any certainty.

ALL Dccd type have a front lsd; maybe Suretrack [ viscous-ish ], maybe helical [ after 2005 ] but they all have it.

JDM bugs with viscous centre can have a Suretrack front- maybe its an option?, And some are open.

UK bugs are viscous centre and open front - without any option that I am aware of, to retro fit front LSD when buying or speccing the car. Ditto the early blobeye's pre dccd, open front diff.

That's the data we hold here and if anyone has any real proof of it being different I'd like to know. Not my mates one had it sort of thing....

Quaife ? Some people speak highly of them.

Cheers David, thats what i wanted to hear as DCCD is the only way i'd have one.

LOL another dumb question but what is the difference between a suretrack LSD and a Helical?

Suretrack is where a viscous centre exerts pressure on a set of friction plates. Helical is where a set of helical screw gears exerts pressure on a set of friction plates.

Helical is more positive in its action and less likely to lose pressure through wear and tear.
