Hey i have a 1965 mustang with stock, non brake boosted single piston disks in the front and drums in the rear. The speed department of the car has been upgraded, but however the braking department is totally stock. I am on a bit of a budget and would like to know what would be the most effective way to boost braking performance. would that be higher quality calipers and disks for the front? or a disk conversion for the rear? I will eventually complete the brake system regardless whether i start with the rear or the front, but i am interested in where i should start. Thanks!
