Those McCrearys on the rallyes..... if they rubbed his springs, that easily fixed on your car....spacers!
I have spacers on three of my racecars. They dont scare me, at all! I made most of mine from steel or billet, with the center hole bored to fit the axle flange. If you want or need spacers, get the billet ones, not the cast garbage.
Just know you might need longer studs. I have 3"studs front and rear with open end lugs on all of my cars that use spacers. (An 11 sec ride, a 9 sec ride, and a used-to-be 8 sec ride).
