yeah talked with dad, and he said that, i should not do this, as the new studs in the dural will deform the spacer and will break faster...
I am thinking on reducing the size from 20mm to 15, or even 10, to use the original studs, yet the guys are saying, not to use original studs with bigger spacer than 5mm...
what is the biggest wheel ET that can be put on without the wheel to have problem with the arches? I have ET52.5 and it hits a little bit the inner arch... Well according to wheelfitment, the max is 38... still not enough...
Anyway, seems like i can not change the studs in the hub without damaging the bearing...
