Yes, knuckles are the same, it's a straight bolt on. Get the 2021 Scat Pack 4-piston calipers, these are the new design and are solid lightweight aluminum monoblock, these same calipers were used on Demon and they look way better than the previous 4-piston calipers, they almost look like 6-pistons at first glance.
Then you'll need Scat Pack 14.2" rotors and that's it.
Here's the new 4-piston calipers on a 1320, wheels are 20's but 18's will clear.
