More Brake for my Coupe
 

I am looking to get some more breaking for my my 2007 EX Coupe without breaking the bank...( no pun intended)

Does anybody know if the larger SI front disc can be swapped with minimal parts.... or am i looking at suspension pieces, wheels and calipers as well ?

On the same note, are the dampers and springs swappable ( or worth it ) as well as other parts like swaybars ?

There should be wrecked Si aroud town by now.
(I know there is always the aftermarket, thanks)
