aftermarket wheels bolts

[Welshy_Pete]

I understand abit more about the bolts now. The alloy wheels I look at mainly and the aftermarket ones are taper ones.

The spacers are 20mm so the thread will be taken 20mm right away.

So basicly I will need 40mm thread to 50mm thread?

How deep do the thread go inside the hubs on the front and back?

thanks
