5mm Spacers: Do I need longer bolts?

[silversleeper]

Well it has finally come time for me to throw some D's on my shit. Problem is, I am torn between a few questions.

1. Will I need to run longer wheel bolts with a 5mm spacer?
2. Where is the best place to purchase BMW specific spacers?
- H&R DR spacers are hubcentric? To E30s?
- I liked the Vorshlag selection, are those any good?
3. I already have centering rings for my wheels, so wouldn't the H&R DR spacers conflict with that?
4. If longer bolts are required, how long should the bolts I order be?
5. Should I just get the 60mm stud kit from Vorshlag Motorsports along with their spacers? (I'm really feeling this option, just want to verify it is what I need)

1-yes.

3-nope. the spacers would have a factory hub ring, so the spacers on the rims would fit the spacers ring perfectly.
4- ~5mm longer than stock (I'm not sure how long that is, I'll check tomorrow though).

1. Yes
2. H&R. The only spacers that are 100% hubcentic are 3mm and 15mm+. Anything in between is most likely not going to be hubcentric.
3. No
4. Honestly can't remember, but the 60mm is supposedly good for up to 15mm? So 50mm?
5. 60mm studs will stick out on a 5mm spacer. If the wheels have centercaps, that could be a problem.
