Below are the updated motion profiles for Assetto Corsa Competizione which include: GT3 / General Tuning - use for all GT3s - based on the 2019 McLaren 720S GT3, 2019 Porsche 991 GT3, 2019 Lamborghini Huracan GT3 Evo, 2020 Mercedes AMG GT3 and 2019 Ferrari 488 GT3 GT4 Tuning - use for all GT4s - based on the 2016 McLaren 570S GT4 and 2017 Camaro GT4.R
Tuned on a DOF Reality P6, but will work for all DOF Reality models. For more information on tuning, see the SRS 2.0 Motion Tuning Guide here: https://www.simracingstudio.com/forum/motion-profiles/srs-2-0-motion-tuning-guide
GT3 / General Tuning
Notes: This tuning can be used as a baseline general tuning for Assetto Corsa Competizione, but has been balanced specifically with telemetry gathered from the 2019 McLaren 720S GT3, 2019 Porsche 991 GT3, 2019 Lamborghini Huracan GT3 Evo, 2020 Mercedes AMG GT3, and the 2019 Ferrari 488 GT3 on Spa, Laguna Seca, Suzuka, and Bathurst. All Max Telemetries have been reviewed and manual adjusted based on new telemetry data. Effect sliders increased to utilize new Max Telemetries. Surge Smoothing set to 5 to mitigate harsh gear shifting surge motion. Sway Smoothing set to 20 to mitigate hard jarring motion during fast sway spiking events. Reaction Speed increased to 100. Heave reduced to 1 to increase road feel/telemetry.

GT4 Tuning
Notes: Tuned utilizing telemetry from the 2016 McLaren 570S GT4 and 2017 Camaro GT4.R, this tuning should be utilized for any GT4 vehicles. Sway and Surge Max Telemetries reduced to match performance of GT4s. Traction Loss Max Telemetry slightly increased due to GT4 performance.

jeff, do u have an up to date acc shake kit profile, i can only see the dof settings. acc, gt3 specifically, thanks
I use the Shake Tuning here for all my racing sims. There is very little difference in the shake telemetry between racing sims since its processed entirely through SRS. The key differences between my experience and yours will be 1) the Windows sounds card volume settings on your PC (which could be different than mine) and 2) the placement and strength of the shakers you utilize.
If things don't feel right, I HIGHLY recommend you to utilize the Shake Tuning Guide here to ensure everything is balanced specifically for your setup. :)
