They are overdriven on a P2 chassis car if installed. On P3 AWD cars, the ratios are equal between axles.Didn't know P3 angle gears were overdriven ratio. Too bad none came with an M66.
I just spent an hour or so looking I do not believe any US cars with the newer style angle gear came with an M66, the early ones all had a TF80. I'm going to double check VIDA. But point being, if there was already a collar sleeve out there to adapt M66 to new style angle gear it would be cool to play around with.They are overdriven on a P2 chassis car if installed.

There are many P3 chassis cars with M66 transmission. US market didn’t get any?
Right but if you look at what the C30 guys have done, some of them can manually control the haldex with an Arduino or whatever and theyve gotten some really good results. Also what contrast was saying is that P3 angle gears are a different ratio so if installed in a P2 car and the haldex is fully locked, the rear wheels would be spinning faster than the front wheels. This is the same strategy in the new Ford focus rs and how they're able to achieve the drift mode. Not that that would be my goal but this would be to possibly overcome the front drive bias of the car. You could play around with the haldex lock up, maybe like 70-80 percent would induce power on slight oversteer but not necessarily be as extreme as a "drift mode."I mean, you're never going to be able to reduce the power output to the front wheels to make the system rear biased. The front axle is mechanically connected to the engine, whereas the rear relies on a pump to control the level of slip, right?
Yeah something like that, I've done a ton of digging on that subject but the people who have sucessfully done it are keeping quiet about it and there's some that got close but didn't iron out all the details. And yeah I think you're right. I think even in it's current form having it locked for track use would be worth experimenting with. I've also heard that even full lock is not truly full lock. I think actually fully locked is sort of harsh. I may be remembering that from a VW haldex video.Ah I think I get it now.
I'd wonder what adjusting it in the R would do. I'm assuming they're using an arduino to intercept and modify the signal. Again, I'm not 100% sure, but I think the R was a bit unique in that throttle demand and input from 4C could cause the haldex to lock up more. I could see the overdrive setup, that contrast mentioned, could cause problems, too.
But maybe not.
I feel that my R could be a bit better, but with IPD sways and KWs, it's got a fairly neutral balance on the whole over/understeer side of things. Off throttle, it'll understeer, but on throttle the back end feels like it wants to come out. But I suppose I have more weight in the back than you do.
What I'm interested is in a beefier angle gear as I need to change mine soon (still works but the splines are thin). Both the one you mentioned and the one for TF80SC are better than mine but could not find any definitive answer if there is a collar sleeve for M66 to work with the TF80SC one. I can get the parts from Eu but only if they actually fit. Do you know?09 V70 D5 from Europe came with an M66 and AWD.

Angle Gear: 36002479
Collar Sleeve: 31325358
Same same angle gear was used in US Market 2007-2011 S80, 2009-2011 XC60, 2008-2011 XC70, 2008-2009 V70, and 2011-2012A S60 according to VIDA.
If I ever see one I would buy it and at least compare ratios and maybe see if it even fits. Would probably need a new driveshaft to the rear. Probably just a pipe dream but that would be pretty sweet to have Focus RS - like AWD.
Nice haha yeah I was turning onto an onramp the other day and came in a little hot and had to lift off the throttle and the whole rear end swung out it was pretty fun! Would love to get that on throttle but I bought the wrong car for that.Yeah, it comes out effortlessly in the snow(duh) and can come out fairly easily in the rain.
There's even an offramp near me that I'd even get some oversteer on with my snows. Scared me the first couple of times I hit it. Not a dangerous amount, but when you're used to no oversteer whatsoever, it was a bit of a shock.
For what it's worth, I'm around -2.4* of rear camber and have my toe set to 0 on both sides.
I don't think there is one. I don't know for sure but from what I've read no one found one.What I'm interested is in a beefier angle gear as I need to change mine soon (still works but the splines are thin).
