Racing Refresh Tech Tuesday: IndyCar Suspension



In a world of a fully spec series that the INDYCAR Series has become since the introduction of the DW-12 chassis in 2012, there are not many parts on a car that has an "open box" that teams can play around with. Engines have the same power out put as every one else. Aero Kits are mandated by track type in the INDYCAR rule book and must be ran by everyone. The key word I just wrote about was "not many", in the world of INDYCAR, not one set of parts can be changed as much at the suspension system. In this article, we will take a deep dive and explain how it works and what teams can do to get maximum performance on race day.


From 2012 to 2017, the series was pretty rigid in the research and development of changes to the DW12 after the series took safety over innovation when it came to the car after the tragic accident involving the loss of Dan Wheldon. Then, starting in 2018, the series allowed some modification to the car involving suspension parts that really separated teams in terms of equipment as all teams were allowed to manufacture and use parts created in house.
