Just installed a set of 15mm spacers on the rear with longer bolts. Now I've discovered some guys are replacing the bolts with studs. The ease of wheel installation is obvious. But other than that are there any advantages to going to studs instead of bolts?

 

Easy off/on and to accommodate spacers. If you aren't frustrated trying to line up the bolts then its probably not time for studs yet. Dont get cheap ones, they break. Use high heat thread lock on them and if you need to remove them use a torch to heat them up and soften the thread lock.
