15 x 7.5 wheel 32mm offset...
 

I'm considering picking up some Konig Lightspeeds and want to make sure there aren't going to be any fitment issues.

with those specs posted no
is this on stock fender na unrolled?

I can confirm they will fit an NB1 that has been lowered without any rubbing.

I have a 91 NA

According to an online offset calculator it should have 2mm more outer clearance than a 15x8 6UL

Should be fine I threw my MR2 Konigs with the same specs with 225 r1r's on the miata and they fit no issues

Should be fine with a slight roll in the front if you're lowered just to be safe. I had 15x7.5 +30 with 205/50/15 Star Specs and it caught my lip in autocross, and it was rubbing on the screw that holds the fender liner in on top. Here's what my ride height looks like
