Subaru (R160 diff) Rear Locker project

ah ok fair enough, so is this a trial for the forester?

Nope, I want to put it in something with a locking centre first as that will properly put it upto the test. See if it can handle it, if anything breaks like CV's or the diff internals or the locker itself. Then put one in an AWD Subie like my car and go from there..

Some lucky person can test it in their car for me as I won't have a locking centre..

I've got a locking centre :twisted:

And I know some choice tracks to test this sick puppy on :twisted: :twisted:

So to clarify, it's going to be a manual locker yeah? :D

This makes me excited, but not in a dirty or big kev way... Time to start saving!

Cheers

:lol: :lol: :lol: How do we explain 'Big Kev' to our mates across the lake?!!!

Before anyone asks ... NOTHING to do with a politician.

I'm on the way for a manual rear difflock that will be operated with air, as soon as it will be installed (in 4-6 months), i'll let you know
 
I'm interested too. Time is just getting away from me on this project, plus not having a computer to properly work on doesn't help with research and designing either :(
 
I met in Valloire (France), which is the biggest 4x4 meet of the year, a guy that transforms Suzukis for trial, and he makes difflocks and other goodies...and he was interested to have a look at my Forester, because he loves those cars that are a bit "different" as the usual big and full equipped ones !

So, last wednesday, I drove 500 km to see his atelier and talk about the project with my "old" rear diff and the 2 axles. He thinks it is very possible to put a Suzuki 413 diff in the rear because there is enough place, but only with a R160 without LSD because the rack and pinion are larger. Mmmmmh, sounds good !

Oh, I forgot to answer Stilson, I already have a Quaife in front but I think about another difflock in the middle, it should go in because I have read here somewhere that they are about the same size, am I right ?

I really don't know I'm sorry, but I sure hope so! Do you have a link to any info on the quaife? What is the principal of operation?
 
The Quaife diff works like a Torsen diff, its made in england, has life warranty and works perfectly as long as both wheels have grip, but doesn't work if one wheel is in the air (no grip at all)

If I put a difflock in front (and rear, of course), I also have to put one in the middle because the central LSD is not strong enough, so my plan is a difflock in the middle and in the rear and keep the Quaife in front, which means at least 3 wheel drive...am I right ?
 
Does feathering the brake cause it to engage?

Does it have any detrimental effects to handling like increasing understeer?

Have you considered a DCCD?
 
I don't know if I understand the 1st question,sorry, but if so, when I brake just a little with my left foot, the torque goes on the wheel with most adherence

I'd say that in a curve, the torque goes on the wheel outside of the curve and makes the car oversteer but it depends the surface

Not yet, because I don't know if the DCCD can be locked 50/50
 
Yeah, you interpreted my first question correctly. Sounds ideal to me. I found them for sale for 600 pounds in the UK but they are only listed for the front in a 6spd STi and rear in impreza. I'll email them.

It is my understanding that the DCCD when in 50/50 lock acts stronger than a 20kg Sti centre but does not lock completely.

Would be very enjoyable in unlocked mode also.
 
The Quaife diff in my forester is for a 1st gen impreza, bought 550 £ in 2005

The company that will do the rear locker is called ERM (etudes et réalisations mécaniques), www.erm4x4.fr , you can have a look ! I have to wait a few months because they move...about 300m in a bigger house ! And because it is a prototype he has to think to make it enter the subaru diff :lildevil:

jf1sf5, you will have LOTS of people on here very interested in the ERM locker :lildevil: Please keep us posted on any updates.

My understanding of the DCCD centre is that the driver dials in whatever ratio he/she wants & the diff sticks to that, whether it is 20/80 or 50/50. I'm not sure if it "locks" the diff though... It is certainly a step up from the standard vLSD centre however. It also seems to be pretty strong going by the high performance engines some hook up to it :twisted:
