Do Pirate jack disc brakes widen the front track?

The pirate jack kits are just 73+ Mopar disks. That’s true whether you get the ones that are BBP or SBP. The only difference with the SBP kit is the rotor, they’re drilled for SBP and they have a smaller (and thinner!) center register. Other than that, they’re just 73+ disks, which widen the track with compared to the drums as described in the TSB posted above.
