The RX1 nd JDM 01~03 RS use the same grille, which the RS badge is normal font while the EK RS is italic font. The EK RS badge can be used on RX1 grille by snapping off the 2 pegs and attach with tape. The RX2 grille is totally different from RX1 and it has no base plate molded on the grille. You can use the EK RS badge on the RX2 grille but need to mod a bit since the size of the grille is different from EK. Why don't you just get the original RS which is only about $85?
