Radial tire to leaf spring clearance

I know you need a lot for slicks. But how little have you gotten away with on a drag radial, used occasionally on the street? Im running 28" tall tire in an a body. Not autocrossing or anything. Real world experience perferred.

You can't even put your finger between the tire and spring on my car. No issues or signs of rubbing.

Thanks for that info. Mine are close too, 1/4 inch gap is all. Enjoyed watching your car at Keystone a few months ago.

Thanks buddy. I'll try to measure it tomorrow for you and get an exact #.

I'm guessing it's around 3/8"
