IndyCar is mandating changes to the new Chevrolet and Honda aero kits for this weekend's Grand Prix of Long Beach to reduce the amount of debris flying off the cars.

IndyCar asked Chevrolet to add a tether to the winglets from the assembly or remove the parts all together and wants Honda to add reinforcements to its rear wheel guards for Sunday's race.

The new aero kits caused problems through the first two races by breaking off and littering the track or flying over the catch fences.

A woman standing near a concession at the St. Petersburg race suffered a fractured skull when she was hit by debris and the race had numerous cautions to clean up broken pieces.
