CLASS RACER FORUM - View Single Post - Tire Help for Heads-up Manual Transmission Class

Rich osmond · 04-24-2023, 02:31 PM

I am building a car for the NMCA Coyote stock class (sealed factory engine ~500HP, 3000# min weight, and g101a transmission). The cars 60' in the mid-1.30 range, and run ~9.7's. Nearly all of the cars in the class run 26" x 10" M/T stiff all slicks, but I am wondering if there is any advantage (or disadvantage) to running a 28" tire with the appropriate gearing. Any experience is appreciated!
