If you mean the 343M wheels that Are for M5/M6 then yes i think they will fit. They are 20x9" ET 34 front and 20x10" ET 34 rear. M6/M5 use 265 tires in front and 295 rear but the M5 has slightly wider front fenders so you might want to go 255 in front. No problem with 295 rear cause rear fenders are same as M5.
I have 20x9" ET35 BBS CH-R in front with 255 tire and its completely Flush with fenders.
