The description is the same for all the DRS sizes.
The 5mm spacers are so thin that hub center on the OEM hub is longer and passes completely through therefore, a hubcentric is not required on the spacer.
For the same reason, 5mm is so thin that the OEM studs are long enough, so the DR set would have been cheaper.
H&R of course wants you buy there studs.
Please don't misunderstand, there is nothing wrong with using the studs that cone with the spacers, just not necessary with only 5mm.
It is you car, do it the way you want.
Either way it is a very simple job that you can do yourself.
If you are not comfortable doing this yourself, I would be happy to help you.
We are talking about less than one hour work.
I can help you here as I have all the tools needed.
