Anyone bought BMR lower arms with spring perch?

I just picked up a set of BMR AA034 recently. I haven't installed them yet. I am going to swap my car over to the North Racecars Cobra R brake setup front/rear. Figured I would change out the lower control arm while I am doing that and possibly gain some clearance for my 17x8 rims when making tight turns. The control arms do come with standard ball joints so I may swap them out for the 94/95 Mustang ball joints for when I install the 94/95 Mustang spindle. That way I don't have to use a spacer below the nut. Then again I may just use the spacer, I have both already.

I waited for LMR to get them in stock. When they did I jumped on it because they had the 6% off plus free shipping. My pics show bolts but they aren't included. I ordered them from LMR as well.
