I Found 3 LEAKED Real Life NASCAR Setups, can I win a race with them on iRacing?

When sim setups meet real NASCAR blueprints, chaos and competition follow. After the first viral experiment, DJ Yee J returns to iRacing with an even wilder challenge — testing three real-life, race-winning setups across three different NASCAR eras, all built by professional crew chiefs. But this time, it’s not just testing — it’s personal. Because if Ryan can beat him in at least two out of three, DJ is stuck streaming Draft Masters until he wins. Stakes set, pride on the line, let’s roll.

• How different can a 2008 Carl Edwards Texas setup really feel compared to iRacing’s fixed version?
• Will a 1991 Davey Allison Charlotte sheet from Larry McReynolds still hold its own against modern sim logic?
• What happens when you throw Michael Waltrip’s 2002 Daytona setup into iRacing’s current draft physics?
• And who actually comes out on top when virtual tuning meets old-school engineering?

Each round ramps up the intensity — from tight corners and twitchy throttle control at Texas to downforce wars at Charlotte and pure drafting chaos at Daytona. The results aren’t just about lap times but about how far iRacing really mirrors reality, and how much “feel” still separates sim racers from the real deal. One thing’s certain — this is no ordinary setup test. It’s a showdown between eras, engineers, and ego. Watch it all unfold and find out who walks away with bragging rights.
