as far as spacers go, the h&r ones are very high quality spacers, but, i would not get them. whenever someone asks about them, i always recommend that they dont get them. i had them over the summer, and there are a few potential problems; the inner lugs can come loose, you constantly have to keep checking them to make sure that they dont come loose, there is extra stress put on the wheels bearings, etc. none of these things ever happened to me, i only had my spacers on for a week before i got rid of em, but these are all things that people who had spacers told me, and by the end of the first week with them, i was very nervous everytime i got in my truck. so my recomendation is to not get them, its not worth it, if you want your wheels to stick out a little, get different wheels with a lower offset.
there are other guys on the forums, such as gerald (gjarret) who are pro-spacer, but he is using them for an off road application - not a daily driving street application, so he has no problem checking them every once in a while.
in the end its up to you, but i hate to see people make the same mistake i made, because it was a big one.
