Maybe interested for my AP 9660 front and rear Paragon BBK. Altho, that probably doesn’t help your production volume issue.
Thoughts on P3 vs P2? I could fade a DS2500 (P3 comparable) on the street with hard driving, more dust, tho.
Currently running Porterfield R4-S on the street, which have better mu/temp than even the Paragon R5 and they're silent which is awesome, but they're really dusty!
