Paragon 400mm rotors

[TrackDay]

Has anyone tried these in an aggressive road course scenario? Since I need to replace my rotors for next year anyway I'm considering a move to the 21+ rotors and this looks like a reasonable option since I don't have a 21+ factory center hat.

I have the ACR calipers so it's just a different spacer for them and I can use the larger rotors.

I've run fronts for ~1 year. I swapped from the NOA Brembo P37018N to the non-NOA Brembo P37018 shortly after a few drives. The braking difference was noticeable since the NOA are ceramic based vs non-NOA semi-metallic. Unfortunately, I haven't had them on a road course or with track-focused pads.

From a weight perspective:

OEM Hat: 1.8lbs
OEM 390mm: 29.2 lbs (31 total)
390mm: 25.6 lbs (27.4 total)
400mm: 26.3 lbs (28.1 total)
