Under the chassis of an MX5 NB (1998 - 2000) perhaps the most technically significant thing happens. This is where forces are absorbed, movements distributed and steering input translated into how the car actually feels on the road. Accessories for the chassis often focus on refinements in stiffness, tuning or the way components are loaded during driving. Especially in a light rear-wheel-drive car, you notice such adjustments surprisingly immediately. When the foundation of suspension and steering is also in tight condition, that character comes out best.
