Thanks for the help. Removing the spring is a great idea with regard to measuring ( duh, why didn't i think of that ) As for flaring, the car I have is a pristine 1970 and I'm just not ready to do it to this car. I have rolled the inner fenders however, and camber plates will be on soon. I was hoping I might be able to squeeze 245's in there by maybe playing with the wheel offset, and spring length, to allow the top edge of the rim to clear the the edge of the spring perch. ( I'm mostly refering to the rear ) Any thoughts? Anyway... this is the problem with trying to go real fast with a nice street car. Once I figure out how to drive a little better, I'll think about a purpose built car. Thanks again. Justin
