*Falls over* Hm... although it feels horribly tacky to end up with 3 pinned threads but... how many would vote for getting this thread pinned too? That and perhaps unpin the "mechanics" thread, idk. What do you guys think?

What do you guys think? Could combine the main posts, and we could merge this and the mechanics thread?

I got a simple question. How exactly does traction bias work? I understand that the bias describes the ratio between the front and rear wheels (e.g. 50/50, 40/60) but what effect does it have?
My guess is that a higher traction to the rear wheels make the car more stable and less likely to reach the point of traction loss. However, I can't seem to guess what improved traction to the front wheels would do. My thought process is this; when I loss traction it's always the rear of the car that spins out so how does better traction to the front wheel affect my driving experience?

My thought process is this; when I loss traction it's always the rear of the car that spins out so how does better traction to the front wheel affect my driving experience? Rear Traction bias causes more stable oversteer, with understeer through faster corners this can best seen on the 811/Dominator with Fujiwara rims. Front traction bias cause better turning and initial grip though tighter corners, but can cause snap oversteer through corners if traction is pushed beyond what the car can do, this is best seen on the Coquette/Velierer with Slideways rims. Hope this helps, this is my understanding of how it works through testing setups for the cars mentioned. Though additionally the effects can also be lessend/exaggerated by raising or lowering the suspension depending on how you want the car to handle. e.g. Slideways on the Coquette can get even more turn in with stock suspension, or be given a bit more leeway with the snap oversteer on competition suspension though it still has more turn in that with rims that give no benefit and competition suspension. EDIT: Anti-roll also effects how the traction bias works as well as Rally Masters do not give anywhere near the level of turn in than slideways for the Coquette, but cause some understeer through higher speed corners

I tried to use Tuner Countersteer wheels + lowest suspension for my fully upgraded Proto X80 and it feels much better traction than before with Offroad Mudslinger + stock suspension. As for me its now more easier to go through corners. Thanks CHILLI for your amazing job. P.S Sorry for bad Engilsh

By the way, Is there any post with optimal tuning for every car? I guess its very hard to find the ideal settings for every cars due to huge amount of variatons.

Apart from max engine/trans + turbo and that max brakes are not always needed, there is no optimal setup that will suit everyone. There have been several cases where world record times have been broken with various different kinds of setups, so it all depends on your driving style and the kind of track at hand. As Hiberg said it's largely down to trial and error when trying to figure out what makes said car easier to control for you. This document is meant to serve as a guide to help tuning cars, but it appears that there is no "best" setup out there. Most parts come with a trade-off of some kind so you have to pick your configuration wisely.

Pin is needed. This is just so good I swear.
Edit: I'm dumb... I didn't notice that it was already pinned... uh...

Chilli, how do you test out the tires for any special effects? Are they in the game code, or do you run them in a particular car/track setup?

Chilli, how do you test out the tires for any special effects? Are they in the game code, or do you run them in a particular car/track setup? The way I test them started by putting said wheel on various cars to look for things to rule out. For example Tuner - Countersteers was the first unique I was asked to look into and was figured out by noticing that the regular Massacro now handled very similarly to the Massacro RC. By comparing the handling data the only real difference between the two was suspension setup, mainly anti-roll being stronger on the RC. That way I came to the conclusion that Countersteers increase anti-roll and then went on to test for anti-roll differences on other cars to verify, and it was consistent across the range of cars I tested. And then with the knowledge of how anti-roll affects the cars, and how Tuners specificly handle with stronger anti-roll, it became progressively easier to tell if it was a new effect or not on other wheels. Next up was Rally Masters I believe and they were pretty easy to figure out. Starting with the Massacro to look for anti-roll changes it ticked that box right away, but also became far easier to slide around with. That's generally caused by decreased rear traction/increased front traction, so that pointed towards a traction bias modifier aswell. So I then repeated the procedure of testing for those effects on other cars to see if that's all or if there are more effects to the wheels, but that appeared to be it; anti-roll + traction bias to the front. I now have a small collection of cars that help me check for different effects. T20 & Massacro for anti-roll. Massacro, Coq. Classic and Schafter V12 for traction bias. I use the Coquette Classic for traction bias because of its slippery behaviour, making it quite easy to spot traction differences when cornering and the same kinda goes for the V12. But with the V12 I use it to check for turn-in behaviour instead of mid-corner behaviour like on the Coq. Classic. If patterns arise that consistently match certain behaviour differences I consider said wheel "solved" and add it to my document soon(tm) after. I should perhaps add that I dont consider a wheel "solved" until it has been used in multiple races on various kinds of tracks in an attempt to rule out track specific results or lucky flukes. If the resulting handling isnt consistent with previous findings/expectations I go back to the drawing board to look for other effects before I do further testing. EDIT: The 4 cars mentioned are not the only ones I test on of course. I do the initial tests with those is all. A few members have ended up noticing me using the exact same wheel on multiple cars for short periods of time. Not hard to guess what I'm up to, is it?
