I just did this brake upgrade on my car. I used the RL calipers, FB adapter kit, stoptech steel braided brake lines, Z1 Motorsport drilled/slotted 2pc rotors, and Powerstop sport brake pads. I’m unsure of how many others have done this update, but in my situation I had to file down the mounting point of the knuckle to get the rotor to fit evenly within the caliper.
Most of this is pretty simple to do even with little experience. Although I did need a little assistance when it came to getting the old brake lines off. I did the front and rear brakes (OE replacement except for the brake lines). The entire job took me about two days to complete. The cost for the entire thing was about 1200.
If you are thinking of doing this project have someone on call in case you need something quickly. That saved me on a couple of occasions.
Note: As of right now there is an unidentifiable noise coming from the rear brakes. I will leave an update as soon as the issue is found.
