need help on a wheel issue

I went through DISCOUNT Tire Direct. I bought drag wheels DR27 they said they would fit with a 205 55 15 tire they do as far as that goes. I bought wheels end of NOV. 15 came with lugs and wheel centric hub adapters. The issue is the front wheels hit/ rub caliber they are stock calipers car is all stock suspension. I went to local parts store got two flat wheel spacers they are 6mm or .25 thick and not hub centric. trying them wheel sticks out to far . I am looking for advise. on spacers.
the wheels are +10 mm offset 15x7 with 205 55 15 tires. I am guess that a 3 mm spacer may work .
I am new to the e 30 its been a learning curve.
THANKS FOR ANY INFO.
I did search's

This really makes no sense. I'm not saying you are wrong, because you're there and seeing it first-hand, but a 10mm offset wheel should have moved the rim even further away from the caliper, considering that a stock E30 wheel is 30mm offset (in other words, tucked even further inward than those DR 27s) Really peculiar.

Are you sure they sent you the 10mm offset ones and not the 40mm offsets? Check the casting and see if it's stamped/cast et10 or et40.

The wheels they sent me are + 10 mm offset does that sound right.

Yes, if that's what they actually are. It should be stamped somewhere on the back side of the centers. I know what you ordered was 10. but they had two options, 10 and 40, and they could have easily sent the wrong ones. A 40 offset would definitely put the wheel further inward, probably enough to contact the brake caliper hanger.. A 10 offset should definitely miss it, since that would be 20mm further outward than stock wheels, but I don't know what the configuration of the barrel part of the wheels are like. They must have some sort of step that's smaller or further inward than the stock wheels.

A 10 offset should not rub unless the wheel design does not fit in the brake profile. I am not familiar with the wheel you ordered so I can't offer much more. Suggest you look at the wheel and check the casting stamps to see if it really is a 10 offset or a 40.

This is back of wheel and side off box.
I Got two 3 mm spacers and put front wheels all good no rubbing on caliber
not sure why I had to do this. I also have a pic of car side profile of front wheel pushed out very little over stock.

Gman's problem is not with the rims offset, but it's lack of backs pacing. Look at the rims, the have less than 1 1/2 inch from the hub surface to the spoke.

Isn't back spacing and offset one and the same thing? The surface that is put against the hub is offset from the centerline of the wheel.

Not really. Offset is based on the centerline's position vs the rim mounting surface. Whereas back spacing is the space between the mounting surface and the rim spokes. So a rim with straight spokes would have less back space than one with deep concave spokes. Click image for larger version

The original thread length was 23.5mm so 27mm would compensate for the spacer.
