Having issues with my 13 SHO PP. Anytime I apply the brakes I get a very noticeable vibration from the front-end. Almost positive it's coming from the front passenger side. Just changed the brakes today and the problem still persists. Tires have less than 3k miles on them and were rotated when the brakes were changed. Car has almost 34k miles. Any ideas?

Do you feel it though the steering wheel? Or the brake pedal?

Did you replace the rotors as well? Any good pics you can post of the old rotors, if you have not replaced them. If you run your fingers over the rotors, when they are cold obviously, and you feel ridges and rough area (if they are scratched), most likely the rotors are warped, and there lays your problem.

Rotors where replaced as well. I thought that's what was giving me the vibration which is why I replaced the pads and rotors. I don't feel it in the brake pedal or the steering wheel

Sounds like it might be a tie rod.
With the car off and in accessory mode try to move the steering wheel back and forth at a steady pace quickly. If you hear a clucking sound it's the tie rod end.

check tie rods and ball joint for play.

In addition, check that the wheel lugs are torqued properly.  Too loose or too tight can each cause vibration issues.  Do you have directional tires by any chance?  Did you grease the caliper pins when you changed out the brakes?  The pins could be sticking (hopefully its not the piston).

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!

True, Z, the daisy wheels do tend to crack as well.

All the wheels were road force balanced and were properly rotated when I changed the brakes yesterday. Pretty sure it's not a wheel or brake issue at this point

I just had happen to me. Felt a rotational vibration in the accelerator. Mine is a 15, and it was a wheel bearing believe it or not! The whole car had a vibration.

When I did mine on my impreza I wasn't able to get the brake pins in with the brakes so I left it out I got the same issue until I was able to get them in Brian Mobil 1 on YouTube has advise on how to get them in and issues think it's in this episode https://youtu.be/BnSi8nI1188

It is a rotational vibration. Only feel it when the brakes are applied and it's more pronounced when braking at higher speeds. I don't feel it in the steer wheel or brake pedal. Got an appointment to drop it off on Thursday. Hope they find something so I don't have to pay the $70 diagnostic fee for nothing
