It seems this is vary complicated ( moving away from stock Brakes to brakes not intended for your vehicle). Second, if your looking to improve braking, I would assume you will be tracking (otherwise why would you want to upgrade brakes?)
Therefore, IMHO, it seems insane (to me) to put your safety and the safety of others in jeopardy using a untested braking system not designed for your vehicle because you can purchase it for a "Crazy" price ( if your not an expert in this area). To what end? Knocking off a fraction of a second per lap??
This comes from a guy (Me) who had a cobalt SS with an ill-prepared braking system crash into my 4 month-old 2012 Boss 302.I If your looking to increase braking performance, IMO, this is not the place to cut corners and save money.
Just my 2¢
