I had a quick question when I was pulling the d16a6 from an ex in my yard I realized the brakes are a bit bigger. if I wanted to swap those brakes on my 91 rex do I need just the rotors and calipers or do I need the knuckle too?

 

You need to get the knuckle and calipers. If the rotor is good snag it but I would just buy new ones. Also search around about "big brakes" and you will find that the 90-91 Civic 4dr EX knuckles are highly sought after.

 

yeah I know that thanks though.....its just weird though I have a dx crx I had to snag a drive axle from the same car and it fit in the brakes are just a lil bigger on the ex I just thought maybe the nuckle between them was the same on the dx crx and ex and the caliper just mounted a lil off set
