I've lurked for quite a while and attempted to use the search function to avail.

I have an 08 G35 journey sedan with staggered rays. Since I got the 19" rays my stock calipers look anemic. I replaced the rotors with powerstop slot drilled.

If I find OEM Sport calipers what do I need to replace?

Do the caliper mounting brackets match up between the Sport and non-Sport models for the 08 sedan?

I've seen many posts that mention swaps of this nature, but none for the 07-08 sedans.

I just want to find some junkyard brakes and toss them on my G.

 

There are only two stock brake packages available for that year, sport or non-sport. Sport rotors are 329mm diameter, non-sport are 319. I think it's the same year brake kit from '06-'08.

There are a LOT of options for brakes overall because they all shared the same mounting kit, stock Brembo or Akebono's can be found in wrecking yards.
