@GhostSamFISHER well for a high-power RWD GT2RS, 0.39 biasfront will be palatable if it has enough downforce to take a corner at high speed - though honestly i would at least do over 0.4, but if it drives well enough for you then its one of the rare cases it will be fine.

And yeah I manually simulate tyre width differences thru tractionbiasfront

Well written guide, I can see the passion in this.
Warning about fTractionBiasFront though, this shouldn't necessarily follow your weight distrib as configured with vecCentreofMass; Rather it should just follow the difference in tyre width/quality between the front and rear.

For instance, I configure a car that is supposed to have F53/R47 weight distrib. CoM and suspensionbiasfront were calculated correctly and the result made sense. However if i then set traction bias to .53 then that results in an unrealistic oversteering kart. This car is also RWD and has wider rear tyres. Therefore I would set my traction bias in a rear-biased setting, as I should have more physical grip from the rear anyway.

@ReNNie sure unless its a wannabe suv crossover offroad "coupe"

Most other handling mods left me unsatisfied, so I took it upon myself to create handling mods that make use of other driver/vehicle-oriented scripts, mostly by ikt.

This results in a car that handles as close as it could to its real performance, thanks to custom transmission setups that allowed me to give vehicles their real gearing on top of accurate times.

I also support proper custom granular engine sound mods made for lore-friendly vehicles such as the works of LamboFreak, to further enhance the driving experiences of certain vehicles, where all available vanilla engine sounds just aren't on point.

What's Menyoo for? A while ago, I met a user by the name of nyconing on this site and on Discord, who reviewed my early misguided attempts at handling. After some general tips he also let me in on something no one else seems to have picked up on - By having Menyoo set car-specific Horsepower and Torque multipliers, one can make engine power in this game be a little more fluid and rev-based, as opposed to the highly torque-based vanilla setup. While I mark Menyoo as a required mod, you can still run the handling without it, but performance may vary.

Special thanks to Killatomate's Realistic Driving V mod for laying the benchmarks of how to make vehicles perform in a manner leaning towards realism within the handling.meta file.
