@ikt Haha the author of Drive Modes recommends your mod and now you are recommending his/hers. I'll give it a shot then.

@Willief23 Thanks for all of the information. I do not know why I spent so long testing handling without using a mod like that. Just tried out ikt's mod but it was crashing. If I can't get that sorted out I will try what you linked.

However, at the moment I will work on writing a simple mod to help me with testing because I cannot find one that does everything I want. Mainly focusing on testing speed and acceleration right now, though I do need to look into how suspension and traction especially affects speed and acceleration.

It is an add-on vehicle. The handling it comes with is quite poor in terms of realism. I want to completely re-configure the handling. I have a base but it needs a lot of tweaking still since the base is from a different vehicle. I am just getting into it; I still have a long way to go to figure out how the individual values affect everything. I hope that by using as much real data as I can to set the values, the physics engine will provide at least semi-realistic handling given the realistic inputs.

Yes, I am trying to adjusting handling. I have not made any changes yet. I decided to ask here before using trial and error to figure things out.

A wiki states a value of 0 sets the centre of gravity at the centre of the vehicle. Is the centre determined by the origin of the vehicle model or by the centre of the extremes of the model? The former makes more sense to me, but what do I know?
