my '66 sedan is a stock suspension bracket car. it runs 7.40's in the 1/8 and works really well on stock suspension. 8.5" slicks, stock drum brakes work well. i would like to drop the car 2" for a better look, but cant find a drop spindle that takes the factory drum brake. if i bite the bullet and go disc brakes for the sake of dropping my car, what is the best kit for drag racing? any info would be helpful. thanks!
