这是我根据观看HokiHoshi精彩视频时做的笔记整理出的调校指南。非常感谢HokiHoshi以及其他让我学到这些知识的人！他有关于该主题的视频，里面有更深入的讲解，而我制作这份指南只是为了整理出视频中的笔记和关键点。

Building Tips Conversions Engine Keep stock engine, only upgrade engine if pushing to another class Drivetrain More viable to keep original drivetrain Aspiration If you can make power goal without turbo, do it Turbo’s give higher max power but only in higher rpm Supercharger give less max power but through entire rev range Aero Front Try to build without front aero if you can but, if you get understeer use it Rear Whenever it drops points put it on as you can tune away the downforce Tires & Rims Tire Compound Rally/Off Road/Drift Use the associated tires Road Racing AWD cars tire compound matters less RWD cars 1 or 2 tire compound upgrades is nice usually Slick tyres are rarely worth it unless rivals racing Semislick is preferred as you may have rain or offroad Front tire width Eliminated understeer Rear tire width Gives more grip to rear More worth it to upgrade than front Rims Use these to adjust your PI (PI is the car ranking system - A-class is 800) Wheel Spacing Makes the car feel more stable on the side that is spaced Ok to have just the rear spaced as it'll feel more stable Used to adjust the oversteer/understeer balance Drivetrain Clutch Doesn't matter much on manual w/ clutch Transmission Sports transmission is usually best option as you rarely need to adjust individual gears Driveline Used to adjust final PI points Differentials 0 PI Sport is worthless Use race for race Use rally for rally and any offroad that'll involve some onroad Go for off road for fully dedicated off road (Dune jumpers & Rock climbers) Suspension Brakes Nice to have it, it is worth it about 90% of the time Suspension Worth it to get race as it improves handling and unlocks tuning options ARB (Anti-roll bars) Extremely useful for fine point tuning Roll cages / Chassis reinforcement Full rollcage is usually heavy and not worth it Rule of thumb, for each class you upgrade your car over its original class, add one rollcage upgrade ie. if you take a B-class to A-class add 1 chassis reinforcement Weight reduction Forza rewards min/max so go all in or not at all Power builds are usually favored on online racing “Adding power makes you faster on the straights, removing weight makes you faster everywhere” Engine Spend engine upgrades last Intake & exhaust first Oil & cooling Turbo & displacement upgrades for last Cams usually cost too much PI points Flywheel is a great PI adjuster Final Upgrade Tips If you have made it to the end without max PI, go back and adjust little things like, Rims, tire width, Driveline, Flywheel Focus your builds on first unlocking tuning options then getting right tires, transmission, suspension setup If you have a lot of spare PI then go with brakes, clutch, adjustable aero Spend final PI on reducing weight or focus on adding power Tuning Tips General Locked tuning setups (Greyed out in tuning menu) Means you do not have the required options unlocked in the upgrade menu Look for the upgrades with the yellow unlock box Not all cars will have the ability to make every tuning adjustment Differential Acceleration Front Lower % preferred Go for 10-50% Low on track builds, high on rally builds Higher setting = understeer very important for FWD Rear Higher % Preferred Go for between 50-90% Higher power cars prefer higher of that range Higher setting = more oversteer Decelerations Front/Rear Never set higher than acceleration setting Usually go for 0% Lower is more responsive but less stable Higher is more stable with entering corners Center Makes car feel more FWD or RWD Set between 50-80% Rally/Offroad is closer to 50% Track is closer to 80% 70% is great starting value for many cars Brake Balance Brake balance is reverse Sliding to "front" gives more braking to the rear tires Pressure Higher Values mean quicker locking/ABS engagement These settings have little effect so not a big deal to adjust Aero Very unimportant on cars below B-class Front Eliminates understeer, makes car feel more responsive Rear More cornering grip Can make car less responsive by adding understeer Usually end up increasing downforce all around The faster you go, the bigger affect downforce will have, if you want more grip give more downforce Damping Rebound Stiffness Stock is usually pretty good Bump Stiffness Usually comes too stiff Should be between 50-75% of rebound stiffness Race suspension defaults to 63% You typically want bump towards the low end only rasing this if you notice the car bouncing/unstable General Rule If your rear end keeps sliding, increase front rebound and bump or reduce rear rebound and bump Springs Springs Front Low front = oversteer Rear Low rear = Understeer General Used to adjust over/understeer Heavier/lower car should have stiffer springs Soft suspension is less responsive but more grippy Stiff suspension is more responsive but more likely to loose grip AWD/FWD More likely for understeer so lower front stiffness a bit Ride Height General Lower is better Set as low as possible without bottoming out ARB (Anti-roll bars) General Controls entry+mid corner balance Very noticeable on AWD+FWD RWD cars Aim for half way between soft and middle on front Aim for stiff and middle on rear Front Low front will result in oversteer Rear Low rear will have understeer Allignment Camber When you are track racing camber is good Race suspension usually gives too much so bump it down a couple in front & rear Adjust via looking at the telemetry menu (more later on) Toe General Adjust sparingly Toe out = oversteer, response Toe in = understeer, stability FWD/AWD 0.1-0.2 front toe out to give a little oversteer RWD 0.1-0.2 rear toe in to keep rear stable in corner Caster General Higher caster adds camber while in a turn while not affecting camber on a straight Keep between 4-7* Gearing Final Gear If you added power you’ll want to extend and go towards speed so the last line goes just past the end of the graph Individual Gears High power RWD you may want to extend 1st & 2nd to make wheelspin less likely Tires Tire Pressure General No tire wear so this setting just adjusts grip/heat Higher pressure feels more responsive and will loose grip quicker Lower pressure less response, slower loss of grip 26-35 psi for track Higher front psi is preferred (about 2-3 higher in the front) Fine Tuning Details General You need a place to test tune, the race track is a good pace Open Telemetry with T on pc On XBOX go to your setting and switch ANNA for telemetry then down on D-pad Telemetry Tuning Suspension Go to the suspension menu of the telemetry Fully pink is fully compressed/bottomed out, you don't want that (Car can bottom out without suspension bottoming out) During stress the pink bar should be between 20-80% If it is not moving much Soften the suspension If it is moving too much Stiffen the suspension Camber Go to the TIRES, MISC. menu Watch the camber of outside tires Never want to the go positive Want a minimum of around -1 to -0.5Go to the Heat menu Go to the Heat menu Inside of the tire should be the hottest right around the clear to yellow color The difference between the inside and outside of the tire should never be more than about 20*F preferred within 10-15*F If more than 20*F then lower the camber If outside is hotter than inside, add camber If outside and inside is hotter than middle add tire pressure If middle is hottest part of tire lower tire pressure Troubleshooting Oversteer/Understeer Corner entry Understeer (A little bit of corner entry understeer is normal) Adjust tire pressure Lower front springs / ARBs Raise toe out Raise Front downforce Lower differential deceleration lock Raise front bump Lower front rebound If during braking specifically Move more brake bias towards the rear of the car (Move the slider towards front) Oversteer Raise front springs / ARBs Raise toe in Raise differential deceleration lock Mid Corner Understeer (Car will turn in well then straighten back out) Raise rear ARBs & Spring rate Raise front downforce Raise rear rebound & bump Adjust tire pressure, camber, caster Oversteer Raise front ARBs / spring rate Raise front rebound Adjust tire pressure / rear camber Corner Exit Understeer Raise center differential rear bias Raise rear acceleration lock Lower front acceleration lock Oversteer Raise center differential front bias Raise front acceleration lock Lower rear acceleration lock RWD Grip Adjust downforce Bump stiffness Alignment Throttle management Other Responsiveness during transitions Due to damping and anti roll bars Car gets thrown off via bumps / curbs Lower bump stiffness Tire temps arn't getting hot enough Increase downforce Add toe Cold tires and understeer Toe out all around Cold tires and oversteer Toe in all around Too bouncy and shifting weight Increase bump damping and spring stiffness Bad braking Lessen front camber Increase caster Move brake balance towards front wheels Stiffening suspension to the front Low top speed Adjust Aero Adjust final gear RWD Drag Builds Tire Pressure Front & Rear All the way low Gearing Adjust to make sure you grip up in 1st/2nd depending what you choose to launch in Also try to reduce the amount of gear changes for shorter drag race builds Alignment Camber 0.0* Front & BackToe 0.0* Front & Back Front Caster All the way high ARBs Front & Rear All the way stiff Springs Front All the way soft Rear 75% stiff Ride Height All the way high on Front & Rear (Use rally suspension) Damping Rebound Stiffness Front All the way soft Rear All the way stiff Bump Stiffness Front All the way soft Rear All the way stiff Aero Full Speed Front & Rear Brakes Doesn't matter (if you're using brakes in a drag race you're doing it wrong) Differential Acceleration 100% Deceleration 50% Wheelie Builds Take the drag setup and make the following changes Tire Pressure Front Max PSI Gearing Have the first gear line end right before the 3rd vertical gear line as the image shows

or shorten depending on your vehicles power but you want to minimize wheelspin) Alignment Camber Front Max Positive Springs Springs Rear All the way stiff
