I also dont buy in to the keep it all Mopar thing. Its not like Ma Mopar is casting the calipers and rotors. They are all out sourced from other venders who make them for all different makes.
I believe in building the nicest safest car I can and with 2 children under the age of 5 that sometimes means uses parts based on price. Honestly if I had the money I would be using a kit from SSBC.
