If it's the same as a long stud kit there's always a debate as to what to use, I was advised used and went with that in the end because the they have been streched already they won't anymore and taking into account the arps arnt stretch bolts u want them to be the same!! Does it not say in the instructions?! Will dig out the settings I did my long studs too but not sure if arps are done the same or not!!
