The damage to the Acura ARX-02a that Highcroft was campaigning then was even more extensive than the damage this time including a cracked tub. Honda Performance Development air-freighted a fresh carbon fiber tub from California to Atlanta and crew went to work, basically building a whole new car in just 20 hours putting it back on the track in time for the Saturday morning pre-race warmup. http://www.autoblog.com/2009/09/27/patron-highcroft-team-builds-new-acura-prototype-in-just-over-20/

This time around, the team expects to be back on track later today. 

BTW, driver Gunnar Jeanette walked away from this, again demonstrating how well modern race cars protect their occupants.
