I found a lot of topics on this subject but they mostly didn't agree.
So I tried myself. I got the black bumper from the 2dr of a friend of mine.

The bumper fits right on there, the bit under the cornerlight needs a little persuasion to get it into place since the 2/3dr corner is a bit shorter. Now pull the side of the bumper out a bit and determine where to drill a hole to screw the bumper on since that hole is a bit more to the back on a 4dr. That's basicly it. The straight edge along the wheelwell is a bit thinner on te 4dr so it doesn't look a 100% right, but IMO the 2/3dr bumper looks a lot better and i've seen aftermarket bumpers with worse fitment.

The hole that holds the bumper to the fender needs to de re-drilled. I didn't trust the thin piece of plastic so is fabricated this little bracket.
This was the initial setup, I removed it for paint and screwed it back in on the inside to make the gap smaller.

the hole on the left is the original holes, the one on the right is the one I made for the 4dr.

The result, still needs a bit of paint tho...

Nice little write-up, a must for all 4dr owners IMHO - unless they have a huge FMIC

 

nice job.. Looks better than alot of other ones i have seen.

I always wanted to do this on my four door.

 

Looks really good. any other good how to's

 

Cool, always wondered about that.

 

Nice write up.

Instead of the metal strip, you could have used a nut / bolt with a washer on each side. Doing so would pull the body lines together much better IMO.

 

JV you got a pic of that by any chance?

 

The gap would be a bit smaller without the strips, that's right.
The holes are so close to the sides, I'm affaid they will tear.

I'll try putting the strips on the inside and cutting of the ending of the screws.

 

looks real good on the 4dr.... gotta try this on mine...

 

put that metal strip on the inside...that way your body lines will match and it wont pull through the plastic. Right now if you worried about it pulling through it still can but will stop once it hits the metal then you sheetmetal srews are going to rip out.

 

whoa, my brother's clone car:

 

wow nice writeup!!

I'll be doing this sometimes in the future.

 

Nice write up. everything looks good except:



I guess im picky, but thats a little too off for my taste.

 

Once you get that painted Silver, that gap is going to be SO obvious. You should clean that up a little bit.

 

nice, I guess you learn somthin every day.

 

My boyz got the same idea! Look really clean and so many lip option. Good Job!

You are right, I'm that picky too.
This was just to test the fitment, the gap will be smaller with the metal strip moved to the inside. And the L-bracket in the fender needs a bit of staightening.

Should look perefect without that imperfection

 

That looks a hell of a lot better then the 4-door bumper! GJ!

 

Nice DIY, but definately get it cleaned up. I rock the coupe just for the front bumper

 

def looks good.. i like that front on the 4 door

 

nice write up.....i might do that to my four door

 

when I did mine, the bumper support had to be modified or removed. The sides are a little off, but probably with a heat gun and some skills it good be alot better. Even the 2 dr bumper thats a little off is way better than the 4 dr bumper.
(the cheap, crappy fitting corners dont help the cause though)

 

Almost forgot about this thread...

the result:






I know what H-T thinks about that wing.
It's going of in a month or 2, I've got a Seibon CF trunk coming this way.

 

It looks go from a distance but once you get close the shape of the lip on the fender and bumper don't match up. I've learned to like my 4dr bumper.
