Alterations to the Chevrolet and Honda road/street course aerodynamic platforms have been implemented by corresponding teams for this weekend’s Chevrolet Dual in Detroit presented by Quicken Loans.
INDYCAR mandated that Honda teams remove the outer vertical wall of the front wing assembly end fence, attached flaps and strakes.
“We’ve been very cautious of any change that would make the car a challenge to drive and spoke with the manufacturer beforehand to make sure that wasn’t the case,” INDYCAR vice president of technology Will Phillips said. “The manufacturer understood our motivation and supported this action.”
Teams have installed a patch where the vertical wall had been attached to the front wing assembly. There is minimal balance change required by teams, according to Phillips.
For the Detroit doubleheader, Chevrolet has introduced a winglet on the top of each sidepod for added downforce, creating a potential performance increase on the 2.35-mile, 14-turn street circuit.
