M3 look on a 4 door 3 series


nah,... dont do that,...... (sure BMW came out with a M3 model just like your dad's but it was the coupe version)
"you can still make that 4 door bimmer look tight with out tryin to be an M3"
just keep it stock look,........ sick rims and dropped,....... and few other small details
keep the headlights,........ just put some hella bright HID's alround,.... if you have fog lights slap some HIDs on it to,...... (some bimmers come with HID's but its the 4300K temp.......... put some 6000K, 8000K or 10000K,... watever you think is tight)
and also have your Angel eyes modified
here's some examples
modified angel eyes on the left and stock on the right
