Pulsing front brake 2016 LRS
Installed Arlen Ness 15" Jagged Big Brake Front Rotors and Hawk Sintered brake pads. Now when I brake hard, I feel a vibration in the front end. I checked to ensure that the rotors are true when I lift the front end and spin the wheel, and that the new pads allow the wheel to spin freely. On a lift, everything feels and looks correct. Thoughts?

Are one of your brake pads dragging? The wheel would still spin but there could be just enough pad drag to cause what you're feeling. Are the calipers really hot to the touch after a ride? If so that could be your problem.
I have also heard of people filing the edge of the pads down so its not so square. Sometimes that causes a pulse feeling too.

Ijust did pads and replaced my wheels with enforcer wheels...
I not get a "pulse" when at slow speeds just in the front... I called my dealer amd told them that ibwould like them to take a look at the rotors to make sire all is good and explained why and he asked if i just did pads...
Told him why yes i did... Amd he said its normal for about the first 200 miles of city traffic where the brakes are used... Theyvsaid its the pads wearing "true" to the rotors...
Hope this helps you!

Clean your rotors.....I use a soapy brillo pad....on both sides of the rotor....and a spray a bit of soapy water between the rotor and pads ..then rinse well.....
Hey give it a shot...it works for me....

OK, problem solved. First, I changed from the Hawk pads back to the OEM pads, and still had the rough, shaking in the front end when I braked from mild to hard. 2nd, I changed back to the OEM rotors, and the braking was smooth. So, the problem is the Arlen Ness Big Brake Rotors. I'm calling AN to check on their return policy. Will post their reply.
