I got a Torsen LSD as stock on my other car, which is also FWD, and can't rate them high enough.
As it's a Honda and has poor low range grunt, it's set quite loose, so can get on the power mid-corner with no understeer- but does wheelspin easily in the wet as the pay-off. The Coupe could certainly benefit from a loose set-up diff like that.
However from your description you described sounds like a tighter set-up (similar to torquey FWD turbos such as ST Focus), good for traction, but not so good for torque steer- Focus St owners will deny it, but for sapectators it's funny as hell when Pugs with half the power destroy them on wet trackdays, as the ST spends most of it's going into 1 wheel drive.
Is there any set-up adjustment on OBX option? I realy want a LSD, but more like my ATRs Torsen one, less like the one you described.

Well, apart from:

Thats a week or so a year, where you can't drive fast anyway. It's worth braving that week for the improvement the rest of the time.

The OBX is a torsen differential, so there is no setup per say, unlike a more traditional plate diff where you can mess around with ramp angles, the only thing can play with is the washer pressure in the centre of the diff and there are no instructions as to what that does so you have very little off the shelf.

I'm not sure I fully understand your one wheel drive point. I can't remember what the maximum power split you can get on the OBX diff although I have a figure of 80:20 in my mind but that could be wrong. You always have some power going through both wheels, unless you put a wheel in the air and then it gets very confused.

The overall effect is less understeer but more torque steer.

I haven't tried the car in the snow, but torsen diffs need some traction on each wheel (iirc), if you have no traction (wheel in the air) apparently they don't do so well, so if its really icy it could be a problem.

Sorry to reignite an old subject. I am wondering if this was a V6 or 2.0 as I am struggling to find one for a 2.0
