has anyone ever considered the "Damage" that adding s13 gear to the front of a ae/ke does to the brake proportioning?

or even larger capacity calipers in general (rx7, corona etc)

ive had s13 CA calipers on my car for a few years now and havent noticed anything dramatic, but surely the proportioning has to change? and if so has anyon ever had any dramas with such things

just for instance i measured the CA and KE front piston size and found them to be within a few MM (i think i twas 39mm vs 42 mm?)
