Cup alloys, cup suspension (firmer spings and damper), traction perminatly off not jst upto 30 mph, later cups have red brembos i belive, ful cup cars have a cup badge but ff with added cup pack wont, the mirrors are just on the cup i belive but not a 225 with a added cup pack. Also think the pwtrophy did, mines a 225 wiv a lux pack and the cup chassis so again al Sligtly different, a ful cup car would be lacking a few bits inside that a normal 225 or a lux car would have, add sum pics then we can tel what it is
