Thank you. Yes all things considered a sticky throttle at the wrong time could do a lot of harm.
The wheel going back has done most of the damage to the car itself. Thanks.
The thick rear bar was too stiff for the thin factory bar on the front. The car rolled more in the front than in rear. Car felt weird and the overall cornering grip was probably reduced.
Agreed and thanks. Unfortunately nothing could be done about the mechanic, frustratingly the of friend of family member situation made it even more tricky.
