Harder braking
Do you feel vibration in the brake pedal? Not in the pedal, pretty much completely the steering wheel, especially if I hit them hard going into a turn vs. a straight line. And fwiw my yawl/DSC comes on way to early IMO. Hoping restoring 1/2 inch stagger with new 265's in front resolves that
Is the vibration rhythmic? extremely rythmic vs. as the wheel turns, like the cow bell rock issue
Any recent changes to the car?EBC Green pads, turned rotors, added 12 mm spacers because I put 285's on the rear. When my fronts are worn, soon, front gets 265's so I'll eliminate the spacer. Spacer to reduce understeer until new tires. All these can be the culprit by themselves. Much less add them all at once.

But! the brakes are smooth as silk at lower speeds.
