What’s the downside to homologated cars? While they can be made pretty equal – depending on the track – teams can’t make wholesale changes to the car to make it work; there are pretty strict limits on what you can do.

“We can change the springs; there are certain rates of springs we’re allowed,” explains John Ward, engineer for the GAINSCO Bob Stallings Racing team which fields a Porsche 911 GT3 R for Jon Fogarty in Pirelli World Challenge. “The damper settings can be changed. Then we go to ride height … we can change ride height, rake, camber, toe, all of that. And we can change rear wing angle. There’s nothing you can do on the front aerodynamics; that’s basically fixed.”

Ward is engineering his second GT3 car in the team’s second season of World Challenge competition; last year the team competed in a McLaren 650S GT3. Before that, he engineered the Falken Racing Porsche in the American Le Mans Series, and previously worked in Indy cars and prototypes in Grand-Am and ALMS. But it was his design work at Dan Gurney’s All American Racers that earned him notoriety. He designed Eagle Indy cars and the all-conquering Eagle MkIII GTP car. He is the proverbial guy-who-has-done-it-all and has a pretty good idea of how to set up a car.
