CPM 2 Tuning Guide: Mastering Suspension, Tires, and Gear Ratios

Optimizing Suspension for Better Handling

In CPM 2, suspension tuning is the foundation of your vehicle's performance. It determines how your car reacts to track irregularities and how much grip you can maintain during high-speed cornering. If you are struggling with oversteer, the most effective fix is to increase your front suspension stiffness. This provides more stability when entering sharp turns.

Rear stiffness is often a matter of personal preference and specific car geometry. It is recommended to use the "trial and error" method, adjusting slightly until the car feels balanced. Keep your ride height as low as possible to lower the center of gravity. While soft suspension is excellent for uneven roads and provides more grip, stiff suspension offers sharper handling at the cost of a bumpier ride. Always tune your suspension with the specific track layout in mind.

Tip

For AWD vehicles, ensure the front is stiffer than the rear to maintain responsiveness and reduce the risk of spinning out during aggressive maneuvers.

Tire Configuration and Grip Management

Tires are the only point of contact between your car and the road, making them critical for both drifting and racing. Your choice of tire compound should be dictated by your racing environment:

• Street Racing: Choose semislick tires for a balance of durability and grip.
• Track Racing: Opt for track-specific tires to maximize cornering speeds.
• Off-road/Rally: Use dedicated off-road tires to navigate loose surfaces effectively.

Beyond the compound, tire pressure and width are vital. Community players report that maintaining tire pressure between 55 and 65 PSI is ideal for general grip. Increasing tire width—ideally between 110 and 120—will provide greater stability. For those focusing on aggressive cornering, wheel sizes between R16 and R18 are generally considered the "sweet spot" for performance.

Fine-Tuning Gearbox Ratios

Gearbox tuning is where you can squeeze the maximum performance out of your engine. Whether you are aiming for a record-breaking top speed or lightning-fast acceleration, the ratios define your power delivery.

1. Identify your goal: Are you drag racing (acceleration) or circuit racing (top speed)?
2. Access the gearbox settings menu in the vehicle customization screen.
3. Adjust the "Final" drive ratio first to set the baseline for your gear spacing.
4. Incrementally adjust individual gears, testing on a straight track after each set of changes.

For drag racing, shorter gear ratios are preferred to multiply engine torque quickly. If you are looking for top speed on long straights, select higher gear ratios. Note that higher ratios will result in slower acceleration off the line.

Engine Performance and Air-to-Fuel Ratio

A common mistake players make is pushing the air-to-fuel ratio to the maximum. According to experienced players, this is counterproductive. You should only adjust this by 1 to 2 points. Pushing it further causes RPM instability, especially in high-horsepower cars (over 400 HP), leading to erratic shifting and poor performance.

For cars under 400 HP, you have slightly more leeway, but aim for a stable idle RPM of around 900. Boost pressure should ideally be set between 1.0 and 1.3 bar. If you are looking to upgrade parts, focus on a high-quality exhaust system and Stage 1 pistons, which provide a reliable bump in acceleration without overcomplicating your engine's reliability.

Practical Tuning Examples

Different cars require different setups based on their weight and drivetrain. Always remember that what works for a lightweight racing car may not work for a heavy hypercar.

Koenigsegg Jesko (High Speed)

A top-tier hypercar requiring high gear ratios to reach its potential. Final: 3.00 | 1st: 4.00 | 2nd: 2.80 | 3rd: 2.00 | 4th: 1.50 | 5th: 1.20 | 6th: 1.00 | 7th: 0.80.

Ford Hoonicorn Mustang (Drifting)

Designed for performance in drift racing. Final: 3.40 | 1st: 3.60 | 2nd: 2.50 | 3rd: 1.80 | 4th: 1.30 | 5th: 1.00 | 6th: 0.85.

Frequently Asked Questions

Does the same tuning setup work for all cars in CPM 2?

No. Every car has a unique weight, engine, and drivetrain layout. While the principles of tuning remain the same, the exact numbers for gear ratios and suspension stiffness must be calibrated for each individual vehicle.

Why does my car lose speed when I change the gear ratios?

This usually happens if you set your gear ratios too high for the engine's current torque output. If the gears are too "long," the engine cannot reach its power band, causing the car to lose momentum.

Where can I find more official information on CPM 2?

You can visit the official CPM 2 Steam page for game updates and community discussions.

For more updates on development and upcoming features, keep an eye on the official OGames developer portal. Always test your settings on a track before taking them into a competitive race.
