Sorry & sad to read this, doc, Rears are tricky & a pain to put on for 1st timers. Who installed em? They have to use the proper caliper tool. Did they compare OE pads w/ Reds?
Below are what I got (exactly what I shared) & they fit fine. I'm currently on them. If you got the same PNs, they should fit the 1.5/2.0 Nippon-built BM/BN w/o issues. The USDM 2.5s & Mex-built units have different PNs. Have the dealership do a once over. Use the EBC lube that goes w/ them.
These pics were taken upon install last 01/16/18. EBC boxes between car & lifter.
