Anyone else: Mustang track-day wheel size that clears big brakes

CityGeek60Community StarterApr 20, 20262024 Ford Mustang GTOhio
2024 Ford Mustang GT, about 14,500 miles. I want a dedicated wheel/tire setup for HPDE and would prefer more sidewall than the street setup. What's the right way to confirm barrel/spoke clearance around the larger brakes rather than relying only on diameter? Any data points from owners would help.

Don't overfit one forum story to your car. If it still isn't clear on the 2024 Ford Mustang, a specialist hour can be cheaper than another round of parts. Then you'll know the next fork. Happy to compare notes if your setup is different. If the story changes I'll post the new data.

Following up on mustang track-day wheel size that clears big: still happening, but I have better notes now. I'd rather look cautious in this thread than stuck later.

Owner notes beat generic advice here. On the 2024 Ford Mustang in Ohio, I'd fix the thing you'll notice every day before chasing spec-sheet extras. Then you'll know the next fork. On “mustang track-day wheel size that clears big,” that was the fork that mattered for me. Write the result down so the next test isn't a repeat of the last one. Wrote this up on my lunch break.

That's a good start, but I wouldn't stop there. Verify the cheap/easy branch on the 2024 Ford Mustang before a big repair or a big spend. I'd do that before spending real money. Time, temperature, and whether it's in gear are the notes that actually help a shop. Worth doing even if the car feels fine right now. Doing the boring step first on purpose.

Thanks — that narrowed it. I'm going to try the simpler check on the 2024 Ford Mustang first. This is me being the wet blanket on purpose.

Write down what you already tried. A second data point from another 2024 Ford Mustang owner helps more than a generic diagnosis. I'd do that before spending real money. Write the result down so the next test isn't a repeat of the last one. This is the version I'd tell a friend.
