i got an eg with 96-97 jdm 4 lug conversion and want to kno wich calipers will fit on the itr rotors? if not do the mugen ones fit with the stock disck?

 

that setup you have has smaller brakes, 10.3 i think. The spoon and mugen ones, that are designed for a TypeR, with the 5lug bolt pattern and the 11.1 inch rotor's

 

afaik you could use a spoon calipers with a 95 prelude dohc vtec rotors.
correct me if i'm wrong

 

I've got the spoon 4 lug JDM brake conversion set brand new. I'm gonna be selling it real soon, hit me up if youre interested. It comes with Spoon front calipers, spoon front rotors, spoon rear rotors, factory rear calipers. All brand new. Im gonna post it soon, but hit me up for pics if youre interested. Thanks

 

I assume your brakes are 4x114.3 bolt pattern with 10.5" rotor. You can use Spoon calipers but you have to upgrade it to Prelude Si rotors orelse they wont fit.

Mugen calipers required 300mm rotor to work with so there's no way it will work with your stock rotors.
