I have a 1997 S1lLightning and my rear rotor measures 4.75 mm thickness. The manual says minimum is 4.8mm so I am looking for a replacement. The EBC one is about $25 cheaper than the OEM on Ebay. $98.00 to $125 respectively. Does anyone have experience with the EBC? Are the OEM rotors worth the extra $? Does anyone have a good used one for cheap? Thanks
