Hello all. Been working on a 69 Roadrunner and will be doing some 1/4 mile racing when done. Question I have has anyone run a 315/60/15 M/T street et pro on a stock suspension? How much squatting does it come to hitting the top of a 29 or 30 inch tire? If there is only a 1/4 or 1/2” space between the panel or leaf spring is that ok? Or would it be better to run a 275/60/15. 3:73 gears. Thanks for any info. I am very new at this
