Three Indy Syclones were used at the Indianapolis 500 race on May 24th, 1992 with the only modifications being a sticker package. One of these Indy trucks was converted into the PPG Syclone Pace Truck (though it was not the official pace car) with significant modifications, including a multi-colored silver, magenta, and aqua paint scheme, a molded in light bar in the roof, a racing fuel cell and fire system.
