Technically speaking, perhaps the most is happening under the chassis of an MX5 NB (1998–2000). This is where forces are absorbed, movements are distributed, and steering input is translated into how the car actually feels on the road. Chassis accessories often focus on refining stiffness, tuning, or the way components are loaded while driving. It’s precisely in a lightweight rear-wheel-drive car that you notice such adjustments surprisingly immediately. When the foundation of the suspension and steering system is also in top condition, that character really comes to the fore.
