Ford made a big deal about the Mustang GTD's rear suspension when the car debuted in 2023. That's because the setup is unlike anything used on Mustangs in the car's 60-year history. It's a semi-active inboard pushrod setup developed for the new Mustang GT3 race car, and Ford is very proud of it. The company is so proud that it's literally on display in every production GTD through a "suspension window" where the back seat would normally be.
