INDIANAPOLIS — Three months after Justin Wilson’s death at Pocono Raceway, IndyCar is taking steps to reduce crash debris and improve safety.

The open-wheel series announced Tuesday that it will tether its aerodynamic components beginning next season. The high-tensile tethers are expected to minimize the possibility of debris flying around during accidents and hitting fans as well as drivers in their open cockpits.

Last season opened with concern over debris from the new, more brittle chassis, so series officials instructed Honda and Chevrolet to makes structural upgrades to the cars. After three cars flipped over in practice before the Indianapolis 500, series officials took away extra horsepower, and an equipment change was made after James Hinchcliffe sustained life-threatening injuries after a broken suspension piece pierced his left leg at Indy.

Under the changes announced Tuesday, the rear beam wing and rear wheel guards will be tethered for all IndyCar events and the car’s nose will be tethered on superspeedways ovals.
