It seems that all of the answers involve rims that are 7 1/2" wide with a ET35- mine are 7" wide with a ET35. The 1/2" difference is 12.7 mm. Does that mean that I do not have to run a 12mm. spacer and that they are a direct bolt on? I am still a little confused- please educate me. I know that I have seen pictures of these rims on VW's before. BenT's site even has a picture of a truck that looks exactly what mine would look like with the rims on it- except mine is banged up, rusty and muddy.

Mario,

You are correct in that 1/2" is equal to 12.7mm. However, when applied
to your wheel, it translates to 6.35mm on each side.

The stock Carat alloys at ET32 and 6" wide should translate to:

76.2mm from wheel centerline to the edge
+32mm ET
108.2mm total from the centerline to the inner edge

Compare that to your wheel at ET35 on 7". I am assuming you are
looking at wheel stampings and not your own measurements:

88.9mm from wheel centerline to the edge
+35mm ET
123.9mm total from the centerline to the inner edge

That loosely translates to 15.7mm further inward than the VW alloy
wheel which would normally be fitted there. Look at your existing
wheel and see if you have space for another 15.7mm.

Or if you have steel wheels of 5.5" at ET30.... (69.85 + 30mm =
99.85mm) 123.9mm - 99.85mm = 24.05mm from you present steel rims edge
to the point where your wheels will end up being. Math is not my
strong suit so someone correct me if I screwed anything up.

I hope that helps. We've written about these question extensively in
the archives if you want to dig up more info.
