Mustang track-day wheel size that clears big brakes

DailyHunter68Community StarterApr 24, 20262024 Ford Mustang GTCalifornia

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? I'd rather test this logically than start replacing parts.

Treat this like a math problem, not a vibe. GAP, paint, and nitrogen are optional until you run the 2024 Ford Mustang numbers without them. If they balk, that's your answer. Not gospel, but it saved me a headache. I'd rather be boring and correct. PPI guy I use is booked until next week, so I'm waiting.

I would not stare at the monthly. If they're pushing term length to shrink the payment, the 2024 Ford Mustang price probably got worse. Then the comparison gets honest. This is from a 2024 Ford Mustang in California. If it doesn't change the out-the-door or the repair estimate, it's noise. Not wiring anything in the meantime.
