Late to chime in but I met the Brembo Director of Operations for North America at SEMA Las Vegas a few month ago. He told me straight out- Go to the Baer booth and get measured.
Brembo has no plans to make a kit for 4th gen Rams because each sub model has a slightly different set up. Big Horn, Laramie, SLT, Sport. He said it makes no sense to Brembo to chase this market. He sat me down with a tech to see if it would be worth it to fab some brackets and make a one-off kit for me. I smiled politely when he offered fronts only for $8500.
Made the Big Baer brakes seem like a bargain at $3900 fronts only.
If anyone can make this work for under a couple grand your gonna have a lot of requests for pictures and step-by-steps.
