IndyCar Tests New Brake and Damper Technologies at Indianapolis Motor Speedway
INDIANAPOLIS – The IndyCar Series recently conducted a crucial test on the 2.5-mile oval of Indianapolis Motor Speedway, focusing on two potential technical upgrades for its current and upcoming car models. The test featured notable drivers, including Alexander Rossi of Ed Carpenter Racing and Takuma Sato from Rahal Letterman Lanigan Racing.
The primary objective was to evaluate a new brake package from Performance Friction Corporation (PFC) and two unique spec dampers from Ohlins, aimed at enhancing car performance, particularly on ovals. Traditionally, IndyCar has utilized a standard brake setup for different track types, but plans for a custom oval caliper with improved response characteristics are slated for the 2026 season.
Rossi and Sato tested the modified brake setup in their respective Chevy and Honda entries, responding positively to the new six-piston calipers designed to improve grip and response, especially after high-speed runs. “What we’ve started to look at is, there’s an opportunity to really enhance that package when it comes to ovals,” stated Mark Sibla, IndyCar’s Senior Vice President of Competition and Operations.
IndyCar has used six-piston brake calipers since the debut of the Dallara DW12 in 2012; however, a transition to a lighter, four-piston rear design is anticipated. Additionally, the series is exploring a potential switch to a spec damper solution, particularly as costs for current custom dampers have escalated dramatically over the past 14 seasons.
“It’s also an area of differentiation that teams are using to compete against each other,” Sibla explained. “This test was immensely helpful to gather feedback as we consider the next evolution of our chassis in 2028.”
Both drivers reported strong brake pedal feel and responsiveness upon entering pit lane, which is a critical factor given the high-speed deceleration required from over 200 mph. The upcoming changes aim to address longstanding challenges faced by drivers during pivotal race moments.
The next steps involve analyzing driver feedback against data collected from the DW12’s onboard systems. The findings will be discussed with team owners to align on advancements for the future.
“We’re looking at this as an implementation for the ‘26 season, and I think it could be used at all ovals,” Sibla noted, emphasizing the priority of the Indy 500. The test indicates promising developments that could enhance driver performance and safety moving forward.
