rear wheel question

[edram454]

the wheels I bought have the following dimensions: 17x11/ offset 50mm/ bolt pattern-5.120.6.5/ hubsize is 70.7/ and back spacing is 7.97. i realize that the wheel studs cannot stick out past the spacer and must be trimmed. apparently there is a run on these rims because now they are very difficult to get. even oe wheel is out of them and they are the main distributor of these wheels in the country. I was not able to find a chrome a mold that fits a zr1 with 36mm back spacing. nobody has any. I will try to use what I have and try to have oe wheels pick up some of the cost of the spacers. they want to work with me so I think they will.
