Adjustable Suspension
Certain roadster models offer adjustable suspension systems, allowing drivers to fine-tune their vehicle’s handling characteristics. With the ability to change damping rates, ride height, and stiffness, car enthusiasts can customize their driving experience based on preference or specific road conditions.
Suspension Tuning Settings
| Tuning Setting | Description |
|---|---|
| Compression | Determines the rate at which the suspension compresses when encountering bumps or uneven road surfaces. |
| Rebound | Controls the speed at which the suspension extends after compression, regulating the wheel’s contact with the road. |
| Stiffness | Affects how much the suspension resists vertical movement, influencing body roll and overall stability during cornering. |
| Ride Height | Refers to the distance between the ground and the chassis, impacting aerodynamics and ground clearance. |
Handling Characteristics
The front suspension greatly contributes to the roadster’s handling characteristics. A well-tuned suspension system can enhance maneuverability, cornering ability, and feedback to the driver. By optimizing geometry and damping, engineers strive to achieve the perfect balance between comfort and performance.
Suspension Geometry
