Backing plates.
1st pic. A modded OEM with a 3" tube, and the 2" Stillen.
Found out that the modded OEM doesn't have enough offset and flexed into the rotor when the steering wheel was all the way to one side.
The oem has an offset of 3/16". The Stillen has an offset of 5/16". The OEM thickness is .032" The Stillen is .038".
