Extended studs/Spacers

[Lukasls430]

Im trying to put these wheels on my LS430. They don’t clear the front calipers, so I was gonna buy some spacers. I’ve seen people do 15mm in the front and 25mm in the back. I was planning on doing this but someone informed me I would need longer studs to accommodate the spacers. Based on my research the stock stud has a thread length of 40mm. So I was think of buying 60mm studs for the fronts and 70mm studs for the rears. Does this sound doable? I’m not very knowledgeable in the realm of fitment/wheels so any input/ideas would be very helpful. Thanks. (These are rims off a sc300, 16x7)

Go get some rims with the proper diameter and offset. Moving wheels outboard puts tremendous stress on your bearings, linkages and the drive system. You are going to make yourself a lot of reliability problems if you do this.
