ex vaux - ignore the salesman - in the wet run in the second green, almost in the orange (although you should always fully open the diff for parking and I run like that when it's dry) and you can adjust it as you drive along if you want i.e lock it up some under braking, open it out as you apex/exit - have fun with it - it won't break.The only thing the subaru instructions say is don't adjust it in mid air....)[/QUOTE]

is it meant to clunk when fully locked?[/QUOTE]

Yes, thats perfectly normal, also you will notice some resistance in the steering too.

 

Can I join in, and complicate matters, by extending this debate to DCCD-A? If not, then no worries

I've always left mine in Auto, and I'm incredibly impressed at how it seems to maximise traction in all circumstances (well, all circumstances that I have experienced so far). And it does clunk at low speed/sharp turns, FYI.

But am I missing out on an improved experience, on the track say, by setting it manually? Or is it a case of "computers know best"? How do the DCCD experts think "A" mode compares to a manually configured setting?

 

Tim go away this is DCCD only ok!! lol :-) just kidding

 

Well, the automatic setting does exactly that, vary the locking capability automatically!

That means it will try to maximise stability by changing the lock depending on certain circumstances, which will make the car more efficient at covering ground with the minimum of fuss, but may not make it more fun to you, as the driver!

As a general rule, the car will go more sideways the less lock there is, so set it low and give it a try!

Just take it easy until you get a feel for it....

 

DCCD A - what he said above Track days are for fun - experiment, build up speed slowly and try it in lots of different settings - somewhere like Bedford where there's nothing to hit.

When I had the old viscous diff in my P1 I would mess about on track, swapping tyres in the wet - If I wanted to go fastish I'd use decent tyres - the late lamented Bridgestones PP, for instance. If I wanted a laugh/scare a newbie witless, I'd put the OEM Pirelli P Zeros on and get ready to do a lot of looking out of the side windows - they really were hopeless in the wet. Paddock Hill at Brands was a particular favourite as you can sit sideways all the way from the apex to the bottom of the dip at a fair lick
Ex vaux - clunking on full lock and as you approach full lock is normal - it sounds horrible, but it won't do any harm. You basically don't ever really need full lock though anyway unless you're drag racing ( for the start) or if you get a diff controller like the Neetronic and start messing about with locking under braking, etc. DCCDA does the same thing, but better.
You can see the effect of the lock if you find a big carpark start driving in a slow circle and then gradually wind the dccd lock on - the car will slow as it locks (and start making the clunking noises) wind it back again or lift teh handbrake until teh handbrake light comes on (as that will set the diff to open) and it will speed up again.

If your car is still too loose for you at say 1 triangle into the green in the dry and just into the orange in the wet, then I'd look at the state/quality of your tyres/ geometry set up as it shouldn't be that scary.
