Moparrbust and I bought these mercedes wheels 16 x 7 together, he got two and I got two, I was not happy with the fit as the ET is 35 or 37 not sure ,(mine is now covered up) any way i wanted the wheels to stick out more, I also did not want to use a spacer (persay). so i got with a wheel repair shop and here is what i came up with.
first i alined the hub centric spacer perfectly center, I got the correct bolts along with centering nuts. through the small holes in the rims i drilled the spacer. i then marked it remove it and tapped them both. I bolted the hubcentric 15mm spacers to the wheel, I changed my offset to ET 20 , I do not have tires on them yet,, my other set of drag radials the 315 35 17 do for me what paul's did for him then i will sell these two rims with spacers bolted on them. here are some pic of what and how i did it. jim
you can see the tapered nut and the ball lug.
drilled and taped after centering the hubcentric 100% center
this is what it looks like bolted on
the look from the outside
the ball lugs were ordered 2" long this pic shows how much sticks out the back into the hub of the car,,6 turns
