Far as I know the dc2r/ek9 are big single pot (can someone else comfirm)

If you did want more pistons you can go spoon setup which use oem dc2r/ek9 brake pad size but with more force with 4 pots

The nsx is 2 pots

Everyone uses dc2r setup as it best though for what you got just need to upgrade mc

Make me want do same to 282mm dc2r setup

Can someone post up total price for parts
