hub bore sizing question
 

I have 4 rear ap2v1s that i want to put on my car. From my understanding, the hub bore sizing on the front is 70.1 and the rears being 64.1. If i were to order spacers for the front to fit the rear ap2v1s, should i still be ordering 70.1s or 64.1s?

Basically, im not sure what the bore size of the spacer is measuring, the hub itself or if i should pay attention to the bore of the wheels. I think the answer is obvious, lol, i just dont want to make a $100 mistake.

Thanks in advance

You need to either run a 5mm spacer in front to eliminate the hubcentric fitment or bore out the wheel. If you just want a generic 5mm spacer, then obviously 70.1 would be the way to go but really anything will work as long as it's bigger than 70.1.

should pay attention to the hub. the spacers need to clear the 70.1mm bore of the hub.
wheels of any size bore will fit, with spacers that is 5mm or greater. assuming the spacer doesn't have that lip like the hub.

edit: anything thicker than 5mm, extended studs are recommended.

THank you guys so much. I just didnt wanna buy the wrong bore spacer
