Presenting my GT3 pack for Simhub/Dashstudio.
Mclaren 650S GT3 (copy of in-game display):
Mercedes AMG GT3 taken from photo of the real car https://i.pinimg.com/originals/9b/5a/46/9b5a467b47cde24ca502b5e93e5b2994.jpg:
Lamborghini Huracan GT3 (can also be used for the R8 as they run the same software by the looks of it) based on this photo: http://image.superstreetonline.com/...2016-lamborghini-huracan-gt3-digital-dash.jpg and a video I found with a similar layout.
Porsche 911 GT3 R (Replica of in-game screen from AC):
The thing with these GT3 cars, is the display screens are very configurable, so you can pretty much have whatever information you want presented to you with varying layouts, as I have seen from many different videos (for the huracan), so there isn't a right or wrong version.
The Huracan/R8 one I put a bit more effort in, the TC & ABS will change to white when not at 0 and display 'off' as above when set to 0. Also they will flash up blue when the TC/ABS is in use (although assetto corsa does not support that property) - I've seen this on one of the onboard videos. Also the message "brake and clutch to start" will show when computed rpm % = 0.
I could add more cars dashboards if they are requested. The Ferrari has a very wide display screen so would be difficult to replicate on the aspects of screen we tend to use on small screens for Simhub.
