My need for a longer stud was due to the use of a wheel spacer. Not the disc kit.
Both those kits you linked include the studs needed.
Both the kits might require you to relocate/replace the crossmember to clear the booster.
Looks the me like the hub is incorporated with the rotor on the 5 lug kit. But I'm not sure, hard to tell from the pics?
What are your plans for the rear?
