Hey, my brother bought a wilwood 12.5 break kit that was off an civic and the shop is saying that it won't bolt up right, aren't most parts interchangeable between the two cars? are they different bolt pattern or something?

 

The rear brakes should fit, the front will need mods...

see if this helps any .... https://honda-tech.com/zerothread?id=1599156

 

ok so I read that but still a bit confused on why these will or will not work, do I need civic LCA?

 

You need the larger integra master cylinder and brake booster to make the front brakes work properly. I dont know how to quote it but it tells what you need and why in the very last post in the link above.
