in a word... no 
Lift off oversteer - think of an open flat corner... you go in with healthy amounts of throttle, but lift out of throttle sharply for some reason. That unsettles the car, transfers weight fwd and kicks the rear out.
The oversteer is through power, but trying to work out whats really causing it.
Look at the inside rear wheel

I know the car is oversteering - I maybe should have said that
Inside rear.... does it do anything funny/different

so you see the inside wheel stop yeah?
I did to start with then didnt then thought I imagined it.
Not so much locking up and thats way too deep to be still on brakes, power should be on there.
The oversteer seems to start from there... the inside rear lifted... agressive plate LSD then sends all the power to the outside rear and starts it spinning BUT from pics its seems to be leaving curved 11's. So, unsure if its just the initial loading of the outside right starting it off sideways... or the diff locking the rear axle too readily and 'pushing' the rear of the car straight on whilst the nose is turning.
Too much weight transfer?
Not enough suspension travel (extension)
Too soft on the rear?
Too 'slow' on rebound?
That was with no rear ARB so the wheels would be more inclined to stay on the ground.
Fuck knows....

Definitely locks the wheel but I would say it's when it's on the power? seems odd.

Yes the back wheel stops as the front wheels are keep going round. Had to watch it a few times but yes it does that.

Can't see it.
Can't even see it when you pause/play the video quick all the way through the corner. Should see it clear doing it that way but can't see it.

I think it;s because you're trying too hard to spot it, come back later and just watch the video.

Probably. I did at 1st just watch the video, then came up with that awesome idea of pause/playing it quick (like a slideshow) but still couldn't see it.

Quite tricky tying to pause it, as the front wheels look like they stop aswell.

Adam you had anyone look at the Chassis set up? What about Paul at Zen, didnt they drop builds/servicing to focus on Chassis Tuning (as well as mapping) these days?
Not sure how the Mongs on here are going to help you other then suggesting Maccy D's Trays

AK, just out of interest, do you own a copy of Allan Staniforth's Book called Competition Car Suspension? There is a flow diagram in there for combating exit or mid corner oversteer or understeer. If you dont have it, let me know and I will upload it

its more the vid than the cure.... I cant see it again
We've been fucked around this year by a couple of garages.
Had it corner weighed - they did fuck all in reality, just weighed the car
Another place turned it to shit - we had to sort it out in the wet paddock at Anglesey
We've tried 2 sets suspension, different sptings rates, different pre loads, different ride heights, different ARBs, no arbs... etc...
Still stuff to try but the diff is now out to get double checked (again) as i'm not convinced (suppiler in UK says its fine).
To me the rear is just locking (bpth wheels giving power, diff locked) and pushing on.
The inside lifting is something we can work on.... a bit more (less, anticlockwise) rebound would push the wheel down quicker. Harder compression would make the car sit up a bit more. Need to see it the outside rear is running out of travel too.

Do you have the original video and some decent video editing/playing software Adam?

Rob - that would be good. I've prob read it.... got heaps of info. We've tried loads of different things - I think its just the diff, a bit too aggressive.
