Wheel Spacers a bad idea?

[newbe351]

As hard as 6 lug wheels are to come by, I finally settled on a set of 17" x 8" Centerline Eclipse wheels with 275/55/17 tires on all fours. They come with a 4 1/2" back space. I just recently received my 4-inch lowering leafs from ECE (66 GMC). Upon installation of the springs, my tires and wheels will not fit the wheel well. They rub on the inside of the wheel well. After a bunch of measuring, etc., we determined a 3 1/2" back space would do the trick. As long and hard as it was to come up with this tire/wheel combination (plus it took Centerline 4 months to manufacture them), I don't want to redo the wheels. One option is to use wheel spacers. Summit has a set of 1.25" spacers that look like they might be a solution to my problem but the shop I'm working with doesn't like spacers and feel that they are unsafe.

Any opinions or advice from the group?
Thanks
