Im about to do a custom widebody to my car a i was wondering should i keep my back bumper or get a new one.

 

what's ur back bumper? OEM?

you have to at least widen it, but if it is stock then no, you should go all out.

 

I have the oem stock bumber but i thinking of widen it out then going with this RE Amemiya UNDER DIFFUSER molded into the bumper

 

it all depends on what type of widebody kit and how your doing it...

 

yea, but you definitely can't stay OEM.

as long as you widen the rear bumper. i've seen a few custom widebodies that widen the fenders but shrink down back to stock on the front/rear bumper. not cool. make sure you match the rear with the side flares too.
