Okay guys... so i installed brembo GTs on my car couple of months ago, and since then I've been getting vibration ONLY when braking... i have bed in the pads, check tie rods, ball joints, all seems to be ok... just yesterday when i checked with couple of other m3s with brembo GT, my front brembo looks different... let the pictures talk
These are mine..
And these are the brembos on the other m3s
You can notice that my front brembo has lesser number of holes (they go like 4-3-4-3, while it is supposed to be 4-4-4-4), and the rotor hat seem to be different (also they have different clamps that holding the rotor)
I believe the front and the rear should look like this
(rear rotor on the top, front rotor on the bottom)
I have checked the part number on the boxes, they all seem to be correct for e92 m3
For additional information, here are some part numbers on the brembo rotor hat on my car
-FRONT : P0 0891B12A10
-REAR : 90168512A03
So what is likely to be the issue ? did i receive the wrong brembo rotor ?
