Default Re: Front bumper alignment

do you have a front lip drilled into the bumper? if so, chances are you will never get a perfect fitting bumper because the lip forces the bumper out of its normal shape. this is a theory i've arrived to.

Default Re: Front bumper alignment

there's not much which effect an oem aluminum carrier not to align.

1. fender liners not seated correctly
2. bumper cover not sitting flush onto aluminum carrier (missing or loose rivets)
3. white sliders are adjusted too wide, this might restrict how far bumper sits
4. bumper shocks afaik dont have any adjustments (forward/backwards). perhaps something is bent where the bumper shocks mount?

I bet you the lip has nothing to do with it, but I'll try it agin with the lip removed.

Ok. I completely missed this...

Maybe I won't go this route and just do my very best to not look at the bumper / fender gap. Lol.

So I was able to play with it a bit more and adjust it ever-so-slightly. I'd say it's a about a quarter inch out. If this car didn't have good days when I walk away thinking how unbelievable it is.


It would go to this guy

Default Re: Front bumper alignment

so i'm in the middle of putting my front bumper back on, and wondering how much "encouragement" everything takes to get lined up?

a couple of my foam spacers were missing, so i had to make a couple of my own. a couple others fell off so i had to scrape the adhesive and put them back on as close to the original position as i could figure out. when i test fit everything i had a pretty consistent 1/4'' gap to the headlight and felt pretty good about things. however the bumper doesn't seem to want to stay all the way "aft" on the white sliders. is it really that precise of a fit via some pieces of foam and tape?

i checked the brake ducts and they're tucked in where they're supposed to be, and pushed on the suction cup locations pretty hard to try and make sure they were seated, but it's just not fitting quite as nicely as i want it to.

is this just the way it is with the foam spacers and over time things settle in?

so your's is a bit different then the op's. with the kevlar, the suction cups and metal posts is what holds everything in place. have you tried seating the bumper without the fender liners? how does it look?

i can get it to go all the way on the sliders, but it kinda "retracts" back out a 1/2'' or so, as if something is pushing against it.

so if you push with your hands, you can get past the alignment point? but when you let go, it moves the other direction pass the alignment point? there should be 4 suction cups. if they are all present, there should not be that much play. the native position should align perfectly.
