    Sure it's not to do with stability control? If this wasn't a modern car you could be sideways in a hedge or something

    got thinking about this again this morning. could it be suspension bushes - hard braking causing them to move around on the front end?
    not that i'm dismissing your LSD thought, i just dont have any real experience with them

    I have so far only had this on roads, on my 8 trackdays so far this year it has not been an issue I remember, so better surface on track and the brakes would be fully warmed up compared to poor surface/camber with cool/cold brakes.

    I can see where you're coming from. In practice it'd be road surface imperfections or cambers making bushes on one side flex more than the other.

    The effect of those imperfections compressing the wheels and changing the toe/camber slightly, giving one tyre a bit more grip for a few milliseconds, and briefly pulling the weight of the car to one side would (IMO) have much greater effect on the car than the suspension bushes moving a couple of millimetres.

    On a track the surface is grippier but almost always braking hard in a straight line, very few roads are smooth, flat and straight.

    That is pretty much what I was saying.

    It's most likely undulations on the road surface which is made worse by aggressive geometry, such as when you're pulled around on a motorway in the lorry ridges.
