Thank you for the advice, unfortunately, I have tried turning off the vehicle's "God" mode to no avail. The only thing that stops almost all of this issue is to lower the vehicle's mass to its default value, but then you can't smash through things. I am not using ENT, instead opting to use Simple Trainer (https://www.gta5-mods.com/scripts/simple-trainer-for-gtav) so that might be something for me to try out and see if there's any issues.

I have tried lowering the center of mass for the Z-axis and while it has some effect, I have the traction turned up so far that it will likely always go up on 2 wheels when cornering while not using Franklin's ability. On that note, however, I have found that increasing the Z-axis for the inertia multiplier helps curtail a very significant amount of that cornering issue.

Thank you again for the advice, I'm going to try out ENT and see what happens there.

Here's the video. It's still being uploaded so if you can't see it, check back in a few minutes.

So here's something I've been trying to figure out (as well as search) for quite some time. I have modded a specific vehicle's top speed, traction, as well as many other factors (including weight because I like smashing through things) and after one of the first updates, my modded vehicle now stops on a dime when at top speed after encountering just about anything - another vehicle, a barricade, a bullet fired by someone, etc. - and I'm trying to find a possible workaround for this.

My thinking is that it's a built-in limitation of the game's engine, but if there's a file - or setting in the handling.meta file - that can be altered to stop this from happening, I'd love to know about it. Thanks in advance!

p.s. I'll try to make a short video of this in action and post it in the comments.

edit: FYI, I've tried modding only the "fMass" and "fInitialDriveMaxFlatVel" values to only increase weight and top speed but I still encounter this problem.
