I noticed that there was a difference in my braking performance after swapping the valves. Earlier, I would notice that there was a lot more pressure on the front brakes after stopping, but after this change, the braking is a lot more smooth and balanced out. I'm not sure if it's my imagination.
I also bought the 3.0L e-brake cables from the dealer and swapped them out with the new backing plates, therefore I didn't have to make any mods to the backing plates. Just straight plug and play.
The only thing I noticed is after all this is, there's a strange popping sound from the back when I press the brakes now. I suspect that it might be air going through the drilled and slotted rotors from R1Concepts, but I'm not sure. I was told that it's a possibility because the rear rotors are so much thinner than the front ones and it might just be normal for drilled rotors. Anyone else notice this? You have to drive near another car or wall and slowly press the brakes with the window open to notice this sound.
