Suspension dampers (aka shocks) are well-established products, so in this day and age, surely anything you get off the shelf from a high-end brand should be ready to roll, right? Wrong.
Andre Nader of DNA Autosport & Modal Suspension explains some of the variances that generic off-the-shelf products, no matter the price, must operate within compared to dialling in custom bespoke suspension for your car, tyre choice and driving style.
He runs through some key points around ride/suspension frequency and its relationship to spring rates, as well as what a driver might be looking for in order to know that his damper setup is sub-optimal, which includes hopping or skipping on the surface of the race track and instability under braking.
Why remote reservoirs are used, how a 'safe' car balance isn't necessarily fast and how trying to cover up the poor suspension with extreme alignment/setup changes is a slippery slope is also explained.
