I've been looking to add front power disc to my 69 coupe. There are single piston and 4-piston calipers. I assume the 4-piston are better but are they worth the price difference? Also will a wheel with the correct backspacing on the drum brakes still be correct with the disc conversion? I've been looking at Master Power Brakes kits and the SSBC kits. Thanks

I can attest to SSBC stuff. They seem to take quality and compatibility into account. Need to know more about your Stang and what you want to do with it to go further. I still have drums on my '65 Fastback because it isn't driven often.

Its a very nice daily driver, rebuilt 302, rebuilt C-4, all new front suspension and steering parts, mostly stock except for KYBs, 1" front sway bar and a rear sway bar. Plan on adding 17" wheels with 235 or 245/45/17 tires.

4 piston and fixed rotors, are OK, use a floating rotor and it works really well. Single piston, or twin piston, floating calipers are decent, as long as you keep them serviced. There are some real quality kits out there, so it's hard to go wrong. You might think about picking a kit that includes the mastercylinder and proportioning valve specific to your year of car. This way, they've done all the math to make sure you get the correct size cylinder and proper leverage ratio from the booster.
Also, if you haven't done your rear cylinders lately, you may want to pull the dust boots back and check to make sure the cylinders are clean and dry. Then check them again about 500 miles or 3 months later. The strain of a new power boosted mastercylinder can accelerate the piston cup wear.
Good luck,

As long as your wheels are big enough to fit over the caliper, the only problem you should run into with backspacing is hitting the upper ball joint. 4-piston calipers clamp alot harder and more uniformally than single-piston calipers. They should last longer and stop you faster, as long as your tires are up to snuff.
