Bob; They are 5 1/2's If you go this route, you will have to change your Lugs and Studs the rim is thicker and require conicle washers for the lug nuts. I got mine at Bug Performance. I have met Ernie and He has been to my house a couple of times. I gave him my luggage rack for his Speedster,but I don't know if he has installed it yet. I bought my rims about a year after I got my Beck, and I haven't had any problems after quite a few miles on them. I used to run a set on one of my old vw's. I just like the looks of them on an outlaw.
