When I heard Unplugged Performance (UP) recently switched over to PFC for their brake pads, I decided to try out the Street & Track pads. Here's my post Autocross review of them. The CarboTech XP8's I've been running for street & Autocross have been acceptable. They have a ton of initial bite and require a minimal amount foot pressure to bring them up to threshold braking. On the con side, they don't modulate very well, they're frequently squeaky, and single tire lock up was not uncommon. I was looking for a little more modulation and a lot less noise. I installed the UP pads, bedded them in, cooled them off and put the car away for the night. When I drove the car in the morning I was really surprised. They had less initial bite than my XP8's but the modulation was so good I could compensate with a little more foot pressure and then I noticed the magic. The pedal had a very connected feel to it and it was buttery smooth. It felt like really expensive brakes, kinda like a Porsche or Grand Sport Corvette. The icing on the cake was how quiet they were, not a squeak out of them. I didn't know how they would do in Autocross but on street conditions they were golden compared to the wimpy stock pads that I was able to overheat on my original test drive when I bought the car (COVID no salesmen). The true test was at the next Autocross. Between my co-driver and I we racked up to 24 laps on them in on Saturday. In a word, they were awesome! With all the modulation I had less one wheel lock ups. They didn't require any heat up. Far less brake dust. They had an excellent feel and VERY quiet! I couldn't be happier.
