[K20SIRCOUPE]

Not quite. To do the conversion without the full type-r brembo suspension (knuckles, lcas, axles, etc), you need:

Brembo Calipers
S2000 front rotors
8mm wheel spacers

That's it.

s2k and rsx-s have the same rotors...

I would say bolt on with the right offset wheels and prolly 17's
