1) Look around at the sheet metal in the front and rear wheel wells and see if any panels, outer/inner fenders might be rubbing a tire. It might only happen if suspension is set too low, on bumps or on turns. My billboards used to rub in front.

2) Inspect the clearance between the driveshaft and the safety hoop and the tunnel sheet metal. Make sure it is all tight.

3) Check clearance between the raised "Wilwood" logo on the brake rotors and the wheel spokes. I have had those rub in the past.
