A high-end body kit can completely transform a vehicle, but there is far more involved than simply attaching new panels. We examine body-kit design, materials, aerodynamics, installation and the importance of professional fitment.

Mechanical grip and aerodynamic grip are often discussed as separate qualities, but both ultimately depend on the tyres transmitting force to the road. Mechanical grip is governed mainly by tyre behaviour, suspension geometry, load transfer, alignment, damping and drivetrain control. Aerodynamic grip comes from downforce increasing tyre load as speed rises. This technical guide explains how both systems work, how they interact and why a fast car requires balance rather than s
