M3 BMW wheels on a 69 Chevelle Questions.......

[chevyracer8262]

Hello every one I'm new to this site and so far I'm loving what I'm seeing and the info that I'm finding.... I have a few questions on the BMW wheel's, I have a buddy that has a set of BMW 18" x 8.5" AC Schnitzer Type III wheels with a 42mm offset that I can pickup for $300 with almost new tires... Has anyone put those type or a similar size wheel all around on a GM abody? If my maths correct those wheels should have a 6" backspace and I've got no idea if they'll fit the front of my car... Here's the setup I'm going with, tubular upper and lower control arms, 66 Chevelle Drum spindles w/C5 front disc brake conversion, the rear wheels I'm not worried about at all because I'm building a custom Ford 8.8 so I can adjust my rearend width to clear and sit like I want it to. My main concerns getting the fronts to fit...

Any information or suggestions is greatly appreciated,

Thanks
