No rust chips in the paint. It would be nice if they wrapped them in styrofoam as they just wrap and then wrap and pop into each other. However, no problem. They are ideal for using an extended bobby pin. Using a 2.535" ARP extended on my FRS and aftermarket wheels. It bolts on without spacers and will likely accept up to 15mm spacers with no problem. With my 5mm spacer I get at least 18 turns of the nut. Perhaps a 20mm washer would also work, but they usually have their own bolts so you can use standard length bolts.
