The Goal - Adjust and improve the car's handling to suit your driving preferences. Each vehicle exhibits unique handling characteristics. Some lean towards understeer, while others exhibit oversteer. These tendencies are influenced by factors like engine placement, drivetrain configuration, and more. Focus: Our primary objective is clear: to enhance your car's handling. However, this pursuit is intertwined with another crucial aspect: STABILITY . These two elements are interconnected. By prioritizing handling, you might inadvertently sacrifice some stability. The car will become more responsive and agile, but the risk of sudden traction loss increases. Balancing Act: Up to a certain point, improving handling and stability go hand-in-hand. Yet, there's a tipping point where further refinements in handling can compromise stability. For instance, increasing a car's agility can heighten the likelihood of "snap oversteer" a condition that can lead to loss of control during sharp turns. The Sweet Spot: The ideal scenario is to find the equilibrium where the car handles optimally without veering towards instability. Tuning Fundamentals: The fundamental principle of tuning is that the first part of the car to lose grip is the one that is tuned stiffer. For example, take a car with a 50/50 weight distribution. If the front suspension is stiffer than the rear, the car will tend towards understeer. Conversely, a stiffer rear suspension can lead to oversteer. Stiffness, Traction and Stability: Simply put - Softening the suspension increases traction but reduces agility. Conversely, stiffening the suspension decreases traction but improves agility. By strategically modifying the stiffness of the front or rear suspension, you can fine-tune the car's handling characteristics to address understeer or oversteer. Complications: While the concept might seem straightforward, achieving the perfect balance requires careful consideration and experimentation If you increase the pressure, you will get sharper steering, but you will lose grip. The car will be more responsive, but lose traction more quickly. Lowering the pressure improves grip, but it can make the steering feel less responsive. Ideal Tire Pressure I think the sweet spot for tire pressure is between 1.8 and 2.2 bar (26-32 psi) . Heavier cars usually need more air in their tires. Like, a lighter car (under 1000 kg) can go as low as 1.8 bar (26 psi) , but a Heavier one (1300 kg or more) might need more like 2.0-2.2 bar (29-32 psi) . Adjusting Tire Pressure Based on Temperature When setting tire pressure, it's important to consider that tire pressure increases with temperature. As the tires heat up during driving , the pressure can rise by about 0.2 to 0.5 bar (2 to 7 psi) . To ensure the correct pressure, it's recommended to drive for 1-2 laps and then check the tire pressure using telemetry. If the pressure is higher than your target, slightly reduce it. If it's lower , increase the pressure accordingly. Gear tuning in Motorsport 8 is more complex than in previous installments because the developers don't provide a power curve graph, which is crucial for optimal gear setup. Why is it so important? Because your gears should keep the engine operating within its optimal power band for maximum acceleration and speed. We will be adjusting the gears based on the turns. The final drive allows you to stretch or compress ALL gears at once. By adjusting the final drive, you tune acceleration and top speed . The rule for adjusting the final drive is simple: The higher the final drive value, the more acceleration . The lower the final drive value, the higher the top speed . 1st gear - It's only needed for the start. During the race, you never go below 2nd gear, and therefore, tuning the first gear is extremely simple - achieve the least amount of "bouncing off the rev limiter" at the start. Stop, rev up the engine and release the brake. Watch how hard the needle hits the rev limiter and if the bouncing is too strong - Decrease the value of the first gear. If the engine, on the other hand, is "suffocating", then increase its value. On powerful rear-wheel drive cars, you won't be able to completely eliminate the bouncing off the rev limiter, just tune the first gear so that this bouncing is minimal. An ideal example of a tuned first gear is when at the start you hit the rev limiter 3-4 times, and then the wheels catch traction and the revs calm down. Gears 2, 3, 4, 5, 6, 7, 8, 9, and 10? It's pretty simple: Each gear is for different corner speeds. Second gear is for the slowest corners (hairpins, 90-degree turns, etc.). Third gear is for faster corners. Fourth for even faster ones, and so on. I think you get the idea. Third and fourth gears are your workhorses and should be set up as follows. Third gear is for medium-speed corners . You should enter a medium-speed corner, shift to third gear, go through the corner, and have optimal acceleration out of the corner in third gear, and it shouldn't end right at the end of the corner . If third gear is almost over by the exit of the corner and you need to shift to fourth, that's bad. Decrease the gear ratio of third gear so that it ends 100-150 meters after passing the corner. If, on the other hand, the gear is too long, you fall out of the optimal power band (engine RPMs are too low in that gear) and you have to downshift You should increase the gear ratio of third gear . And the same goes for setting up 4, 5, and so on. Why is that? If third (fourth, fifth, etc.) gear is too short, you won't be able to accelerate effectively out of the corner. Either you'll have to shift to fourth, which will reduce acceleration out of the corner, or you'll have to fight for your life in third gear, which will lead to wheelspin. Also, shifting gears during corner exit under acceleration will lead to a snap oversteer. In short, each gear should allow you to go through a turn without the need to shift up or down throughout the turn and exit After configuring all the gear ratios, you might find that the gear are either too short or too long . In this case, the main gear ratio comes to the rescue. If all the gear ratios are clustered on the left side of the graph, decrease the main gear ratio to stretch them out (increase the speed on the main gear ratio). Continue stretching the gears until the last gear either reaches the edge of the graph without going over, or until it touches the beginning of the last column . Similarly, if the gear ratios extend beyond the graph (they are on the right side of the graph), increase the main gear ratio (increase acceleration) following the same rules. Congratulations, the gear ratios are now configured. Camber Front wheel camber - Increasing front wheel camber can improve cornering grip and handling, but it may also compromise braking performance and stability. In front-wheel-drive cars, acceleration can also be affected Rear wheel camber - Like the front wheels, increasing the camber on the rear wheels can improve grip during cornering. However, this comes at the expense of acceleration (on rear-wheel drive cars), braking, and stability under braking. The chamber is adjusted using telemetry. In a corner, the inside of the tire should be a few degrees warmer than the outside. If the outside of the tire is hotter than the inside increase the chamber If the inside is excessively hot (15+ degrees), decrease the chamber . Toe Toe in or out is usually not worth doing. It can mess up the steering too much. But it is done this way. Front Increasing toe-out will most significantly affect corner entry by accelerating the vehicle's responsiveness to initial steering input. However, this adjustment can compromise straight-line speed and stability. Increasing TOE-IN should increase stability in the braking zones and slow‐down the response to the initial turn of the wheel. The compromise is that TOE‐IN will produce an increase in scrub that
