I am stuck in trying to figure out should i replace pads and rotors or shave them down....reason is the front breaks were changed around 131K and i have 144K so its not to late but i had sever shaking due to and aftermarket front suspension i bough off ebay the fake german brand ...any how their rubber is way to soft for X5 its just too soft...bough oem bushings and pressed them into the oem arms and all is well however the shaking has warped my rotors. when braking at 70-80 feel sever shaking in the peddle and once you let go it stops the hotter the get the worse it becomes so I have been lookin at the kits from ECS tuning and wanted to know if anyone has put them and how are they now?
