I'm running the mkclots/morrisun front brakes, they fit under 13" turbines with minor caliper shaping.
another, more indepth swap could be zx struts with a wildwood ultralight 4 piston caliper for a 3/4 width rotor.
its a smaller caliper that works alittle different than the zx caliper, so you can move it in real close for clearance. 13x7et0 libre has plenty of room
df, I had to use a 210 centerlink, pitman arm, and steering arm, (in an emergency) i found that the centerlink was 14plus mm wider from inner tierod to inner tierod.
i figured it was becase the lca pivot was moved outward slaightly. about 8-10mm per side. i think that is why people assume it would widen the width, because the track width is wider, but extended between the lca pivots and inner tie rods.
