as I suppose it's interesting to some
Yes, very interesting as (All IMO pls note) your incident has more data which you have kindly shared than would normally be the available.
Sorry to hear about it Patrick, Neil, & everyone else too.
The background for me is:
Well modified Car, rigid shell, good track day components, tyres, brakes etc
Confident driver inputs, consistent laps, competent wheel man
parcel of oddball scrap in the way ahead but quick enough to be difficult to pass, and a distraction for various reasons - i.e. "this 951 should sit with that thing through here" - but the feeling of the car was otherwise / not there...
semi-proven setup following recent work
the laps feedback were not increasing the drivers confidence in the car - my "feeling" from observing, and the data
Key data is:
at 4min 20/1sec there was a seat of the pants unease with the car's feedback
the G meter was higher and less consistent than previous laps
the throttle position was reduced as a result
(I can relate to all that, it reminds me of a very sad day at Tamburello curve)
What Happened then?
a combination of the higher G intermittently bound the outside rear wheel travel, the trailing throttle acted on the diff unfavourably, the weight transfer was different to other laps, the car did not settle to the bend, the Right rear wheel could not hold on (G & Skid forces), after that it was a choice between what happened or a super drift into the gravel followed by a barrel roll out over the tyre wall & barrier.
If you could make an adjustment pre rerunning that lap, it must be the suspension
Knowing the effort you must have made to build such a car Patrick, the repair is well within your grit.
