no to a lip man,
keep this car simple, your ke20 had way to much going on and the whole thing near the end started becoming a mess. while i enjoy a "JDM" styled car as much as the next person, there is a point where you reach and just need to say thats enough. fenders mirrors would prob be overkill as well. maybe just change up the style of the door mirror.
like you are kinda going for a euro dub look with the flappers and sitting low, but then you want to throw on a lip and some fender mirrors more common on the "JDM" styled cars.
this is my opinion, but its your car troy and this is obviously your style as we've seen, each to there own.
