Great car overall to fill in the GTE field gap and it is even better with ACfans 488 sound.
I had a little issue going over the crest just after Raidilon at spa where first going up the hill I oversteered a little and the car felt like it lifted a front wheel when going over the curb on the left.
Afterwards I then did about 15 laps or so to try and replicate it but could not so it makes me think it is just small nick with the game engine.
Also an idea for your next project, once this is fully to your liking, could be the URD Aston Martin GTE doing it the other way to this and converting it to GT3 spec.
