3rd gen Brakes coversion done!
 

First of all, THANK YOU cymfc3s, sorry for so many questions, and for being patience!

OK so my 91 NA had single piston calipers, I don't know how old brake pads, stock brake lines, and one year brake fluid (the system was flushed).

I replaced the front calipers in favor of 3rd gen red calipers, with Hawks HPS brake pads, and 3rd gen SS brake lines. I also replaced the rear lines with SS, and Hawk HPS brake pads, ohhhh and I also painted them in red:D

Other than COMPLETELY drop in, I had to fabricate the hard line that goes in between the caliper and the SS\rubber line. The single piston calipers don't have this line and the Mazda stock ones are like $15 each, I made them for like $10 both including tools!

How does it feel? The car stops WAY better :p: :D :p: :D So it was a GOOD investment!

I wonder if it would be an improvement for a 2nd gen 4piston calipers.

I heard they are the same (again thanks cymfc3s), I believe the only diference is the weight). So no need to bother with that one!
