I'm trying to find out the limit of how much spacer I can use before I have to replace the lug studs with something longer. I want to add a 10mm spacer to the rear of my sedan, but I haven't found anything on if I can go that thick. On my Toyota, I had to replace the studs (to run the same wheels) with those from a Toyota truck, as they're about 15 to 18mm longer (correct thread though). What I'm trying to do, is move the rear tires out a little, as I don't really care for the slightly tucked look. I'd prefer to flush it up, or get a very slight poke. Keep in mind I'm not lowered and don't plan on lowering the car. Thanks for any help you can offer.
