EC-7 18x8.5 et35 Clear 380mm Stoptech BBK?

Does anyone on here have 18x8.5 et35 EC-7s fitting over the 6 pot 380mm Stoptech kit?

Apex is saying it will work but I am somewhat skeptical, but would love to see that it works.

I went ahead and ordered the wheels, which should arrive tomorrow. Hopefully they fit. I have some 18mm spacers coming as well, which will give the 397 wheels just enough space to safely clear the calipers from the wheel barrel. 15mm spacers leave less than 1mm and I am not going to drive my car in that scenario. I wanted to stick with stock wheels, but I don't like the idea of 18mm spacers. Not sure if the 225/45-18 winter tires I currently have on would rub on the fender, but I am guessing the 245/40-18 MPSS' would give me some issues when they get installed for sure. Looks like I may be going with the new wheels and summer tires a little early this year. Will provide updates.

It looks like the 18x8.5 et35 EC-7 wheel is clearing the Stoptech 380mm BBK. The 18mm spacer worked for the 397 wheels though the clearance is minimal on the barrel. Surprisingly the 18mm spacer looks great with the stock wheels, but I will probably just go with the EC-7s summer and winter going forward, but stick with the stock wheels for another few weeks until it warms up a little more. Here are some pics of the wheels clearing the brake (rotor direction has been corrected and 18mm spacer up front with stock wheel)

I actually got the 18x8.5 et 35 EC-7s installed today and am much more comfortable with the caliper clearance than I was with the 397 wheels with 18mm spacers. There is not tons of room, but there is more than it looks like in this picture and more than the 2mm recommended by Stoptech. I know this thread looks more like a car journal, so I apologize, but hopefully it is helpful to someone in the future dealing with similar decisions.
