Looking for aftermarket calipers that are the same dimensions as the oem ones. I run slicks on a 13" rim so clearance is a concern. Id like to upgrade to dual piston or something along those lines because i run a manual brake setup. Thanks for the info in advance. Car in question is a 94 civic with gsr brakes

 

gsr brakes are 262mm if i'm not wrong?
Im from europe, so im not familiar with "gsr" badge :D
