Subaru (R160 diff) Rear Locker project

Great to hear Taza!
As to the heavier centre LSD, I understand that these can have an adverse effect on ABS, for those of us who have it. :/
 
You can do it Taza!
PS I have a heavy duty cable to donate to your cause.
I guess you could call it an engagement present. Getit?
 
I'm not sure how the centre diff would affect ABS- worth some thought. I hear with a 20kg centre diff you can no longer do handbrake turns. But with an 11kg one I would have thought it would in itself reduce if anything the locking of wheels. Only car I've driven with an 11kg centre diff was a purpose built rally car which had no ABS anyway, so I cannot be sure.

From memory I think you might be right. 11kg is ok, but not the 20kg.

Well that is still 3x better than the stock 4kg. That with a lockable rear would allow you to get through some situations that might otherwise cause damage quite easily :)

Absolutely Taza!
I will be talking to the gearbox mob about this when I investigate getting my new low ratio box built.
 
I have the Liberty LSD rear to fit, but haven't done the box yet.
Now that the SubaXtreme sports bar is on the box will be next.
Possibly a heavier clutch as well - anyone have any suggestions on that?
Would be great if anyone local has a front LSD fitted so that I could get a feel for on-road handling. ...

I would love to hear what they say...

Venom in his H6 beast has a torsen (?) front LSD & normal plate rear LSD. When he took me for a spin around the streets of Ballarat all I noticed was heaps of grip! :cool:

Good to know, I have been told that front LSDs can make the steering feel heavy / 'dead' on-road. Would hate to lose the responsiveness of the OE steering.
 
I've got an OBX front helical LSD, makes virtually no difference to the way the car feels on the road even when booting it and if I want I can retain the ABS which you can't with a plated clutch diff.

I'm seriously thinking of selling my DCCD as I don't really use the car off road enough and I can't be bothered sorting the electrics out.
 
I found the factory helical front diff did make the feel of the steering worse. It is worth it though. Plated rear diff made no difference to ABS- nor did helical front diff.
 
barry it would be best to drive a car with a front lsd, I always take "good" and "bad" opinions with a grain of salt. You're welcome to a spin in mine to get a feel for yourself. I love the front lsd. There is no mysterios slidding off the road in the wet I was told might happen, thats bull****. On the road You get more grip before losing traction, and when you do the car is very controllable unlike the factory understeer. Offroad it's as good as a plated lsd. It does not work when one of the wheels leaves the ground, but neither does a plated lsd. There is a synergy with having both that makes the car very, very capable.

Absoulutely get a 1way lsd, don't touch a 1.5 or 2way. They're for the track!

Thanks for that D-Gen,

I have been thinking about the DCCD however, I think the electrics would be even more complicated for me than for you!

I recon that is the point Rally, to some extent everything is a compromise, it is about being clear on the objective in each case, and doing sufficient research to ensure that you don't discover 'unknown unknowns' after $helling out and doing the work. And that is no mean feat for a mechanical dunce like me! :rotfl:

I totally agree about taking a grain of salt with opinions on this type of thing. In the end it comes down to how it feels to the individual.

Thanks for the offer Venom, I'll catch up with you and have a spin it it just to get a feel of what it is like.

Controlability, the synergy thing and improved off-road capability is exactly what I am after.

Also good advice about only getting a 1 way lsd.

Is yours a 'Torsen'? That is one of the options offered by the gearbox manufacturers in Sydney.
 
The wiring for the DCCD is pretty straightforward if using the DCCD-Pro. Going on memory, there are only 2 wires to the DCCD itself. Then there is power- no different to a radio but using a higher rated circuit, an earth, a wire to the handbrake and a wire for the TPS out from the ECU harness. That is the only tricky bit- you need a schematic to know which is the TPS feed wire, and splice into that. Then just colour match the wires for the thumbwheel and auto on/off switch. There is also a sensor that needs to be correctly stuck to the floor- and correctly means facing the right direction, is flat and is glued in place. Even so, I would have thought am 11kg centre might be easier- and cheaper.

yes. Mine has an Exedy FJK7005HD. Supposed to be heavy as hell, and can be ridden forever I am told.

I have something similar except mine is Clutch Pro (Aussie brand). Its heavy duty, had it in for almost 20,000km. I have had the slight smell here and there from it but onthing bad at all, very happy with it and the car seems to be abit quicker taking off with it too :)
