So I finally completed the PBR dual piston caliper upgrade on my car the other day... what a difference. I honestly wasnt really thinking Id be able to tell the difference but I got the calipers and brackets for 50 bucks so I wasnt going to pass it up. Now that I did the swap though, wow does it stop on a dime. Still using stock rotors but a plus side is that my original rotors were warped and the guy included two replacement rotors in the price. Total spent was 75 dollars after I bought the fine thread banjo bolts. I also ordered the stainless steel flex lines for 90 but Im not so sure if Im going to put them on or just send them back.
