Took my BMW M4 to Buttonwillow’s new track, The Circuit, for a Time Attack with Turn 8, and the goal was simple—can I break 1:50? 🏁

I ended up running a 1:52.9, landing 2nd place behind a 1:52.2 Miata with full aero. Third place was a 1:54 Corvette with a full aero package. In this video, I break down my lap, analyze where I lost time, and discuss the next steps to chase that sub-1:50 lap time.

🔧 What’s in This Video?
• Full lap breakdown at Buttonwillow’s The Circuit
• How my BMW M4 performed against the competition
• Where I lost time & what I can improve to go faster
• Future mods & setup changes to push my lap times lower

This event with Turn 8 was packed with competition, and I’m already looking forward to the next one!

💬 Think I can drop below 1:50 next time? Let me know in the comments!
