The car just got through noise in the morning at 104dB

Anyway the car performed really well on track with oodles of grunt and an interesting change to the handling (it seems).
As with most 7esq cars they are nimble and agile in the turns and almost skip and dance through the corners. The Indy now feels more planted and "car" like.. the 65kg that the upgrade has added has helped the traction and after we (Dick and I) dialled in the tyres and damping (car likes 17psi HOT tyre pressure and a stiffer damping than before) it really started to sing and I had great traction out of the corners.
So pleased to report nothing fell off, no dramas and massive smiles were the order of the day. Noise is still closer than I'm comfortable with but moving in the right direction.
Happy days.
