It drives me crazy having imperial fasteners in my datto.  I want to build some brakes that fit under 13's.  So maybe some factory alumuinum smallish 4 piston calipers.

RL411 sedans and very early 310 1500cc engine Roadsters have 13 inch wheels and front disc brakes.  They both have SAE fittings.  Good luck on finding them !  They also were designed for 13 inch wheels !  Early 510s have similar appearing front disc brakes but have metric fittings, which just may be what you need.

Good luck with that buddy!!!  I checked into a handful of options years ago and gave up.  I couldn't find any options with more modern parts.  The stock 510, 411SSS fit 13's, but it's hard to find the parts and the brakes aren't that great.  I wish I could throw some hope your way! lol   I think the Metro had some small vented rotors.  I don't have any clue about stock 4 piston calipers that are considered small'ish.  

 

At least on the rears, you could probably do an inboard system with the rotors mounted to the CV Joints.....????....maybe??

You would go nuts with a 521.  All the body fasteners are Imperial, the engine and transmission are metric.

Would running dual rear calipers on each front work for you? '80s Maxima, 240sx and 300zx were small and fit a non vented rotor.  A curved backing plate could be bolted to the original caliper mount holes and each caliper would use one of the original mounting bolt holes and one of the backing plate holes.
