For your own sanity, do not also look-up the third version of this car--the Ginetta G55 GT3, which is not in the GT3 category, but instead in GT Open!!

This is what happens when race car manufacturers name their cars for various technical reasons and not for consumer sales/marketing purposes

P.S., it is a very fun car to drive...

 

This is my biggest issue with the game in terms of driving feel and audio - There's this constant scrubbing sound that's extremely present even in a straight line - I can have tire audio down to 30 which seriously mutes the squeals and makes slides, skids and such way harder to hear. However, it barely does anything for the constant Tie Fighter-esque scrubbing that is universally present.

It's extremely annoying and I don't think you should hear even half as much of the tire in a straight line as you do in AMS2.

 

Turn down surface/road noise to fix that

 

This has definitely helped! While I still find the scrubbing noise activates extremely early, this is a definite improvement. Thank you!

 

I already tested this a few weeks ago. (As a setup creator, i always try to find new meats to make the car go quicker)
In the GT3 at spa, i was about 7-8 tenths per lap quicker on 2.0 bar hot pressure compared to running the maximum pressures. You're definitely losing grip in the corners if you go too high on the pressures. It might be different if you go to really high speed circuits like daytona but for the most tracks, i'd say 1.9 - 2.0 bar is probably the ideal range for GT3.

 

Yep, you had clearly less grip in corners earlier as well, but the overinflated tires were giving you so much advantage on straights because less rolling resistance that it seemed to be worth it on some tracks. On some update during this year, Reiza changed the amount of rolling resistance you get to be less on higher speeds, so the difference shouldn't hopefully be as favorable towards clearly overinflated tires that it might you gain more than you lose on corners.

I personally don't notice any clear delay, but it could be also that my brain is somehow used to it. I guess it's also possible that you have some input delay that I don't. I'm generally quite conservative and smooth with my steering inputs, maybe it mitigates this as well. EDIT: have you tried to remove the interpolation filter altogether when playing AMS2? I think it's beneficial with games like iRacing that might not have fast enough refresh rate for the FFB signal from the game. I never ever have thought to use similar filter on my Moza for AMS2.

The GT3 understeer so much on high speed on default setup, that not sure how you can get that swinging pendulum effect with those on faster corners unless you start to lift too much and cause the engine braking to add load to front. Before the changes to the GT3 (including the change to aero loss on yaw), the rear did struggle more on faster speeds and you had more of that rear sliding going in the fast corners.

Just want to be sure, everybody who has issues with the GT3, are you testing with default setup and not some older or TT setups from the past?
