Lip deminsions

I was wanting to know what everything thinks of how far down a bumper lip should be. I'v been designing ones that are 2 3/4" tall. Before I start making molds I was wanting to see what everyone thinks. Is this too tall? Too short? Just the right height?

Are you talking about overall height or just the amount that would hang under the bumper itself? I really couldnt put on a lip that would hang down lower than say 1/2" to 3/4" below the bumper as I have enough trouble getting a jack underneath my stock bumper as is with a 2.25" drop in front (approx 2 finger).

the height of what will accually hang under the bumper. a 1/2" lip wouldnt even be noticeable.

eh now that i think about it I think I have the most trouble getting it under the cross member not the bumper, i'll have to go measure this.
And also the lip comes up on the side of the bumper a little bit to give it some visual height.

Edit: are you molding the lip for a 88/89 front end or a 90/91 with the brake duct/cai/foglight holes?

the ones I'm making dont. They attach to the bottom. and dont overlap any of the bumper, Think it looks cleaner this way.

they will fit 88-91 and dont have foglight holes or vents, but they can be added if anyone wants them.

i would think that the lip sould hang more then a 3/4 in. off the bumper if its gonna be 2 1/2 in. tall but thats just my 2 cents

i'd say at least an inch lower then the bumper anything less then just use the stock lip its like 3/4 in below the bumper and maybe 1 1/4 tall

I think that kiwi should read the post more carefully

i see im half retarded so dont mind me

lol

we need the lip hugging bumper action going on. it would blend in better than a lip that looks stuck on the bottum of the bumper IMO.

Allright, if enough people want ones that overlap I'll change them to be like that before I make the molds. But what do you think on the height BELOW the bumper, right now the one I'm working on is 2 3/4"

if they r made good the ones that attach on the bottom look better, smoother lines

plus if it over laps to much 90-91 crx's wont look right with it on they have the vent type things in the lower part of the bumper

um r the crx and civic bumper the same at the bottom i think the have a diff shape and i believe 88-89 are slightly diff from 90-91 on both models

I dunno why but to me the overlapped part just makes the lip look like part of the bumper here. (http://www.passwordjdm.com/popuplargeimage.asp?strImage=370.jpg&strImageType=product&strPageTitle=Password%20EF8%2088-91%20CRX%20SIR%20carbon%20fiber%20front%20lip)

vs the stock lip which looks like a totally seperate piece just hanging there.
check iT (http://www.superhonda.com/photopost/showphoto.php?photo=20792&sort=1&cat=502&page=9) Maybe make some overlap but don't put any overlap into the vents as seen above.

As for the 2 3/4" hang down I will have to measure and thats going to be tomorrow bc its cold rainy as hell, I dont have any cloths on and im parked 1/2 mile away. School parking rULES!!!

99% sure the bottom of the bumper is shaped the same on both crx and civic for both years, because the deminsions of the bumper never changed, just the styling changed a little in 90

well 90civicDXdude put a 88 bumper on his 91 and the lip was a hair longer on the 88 bumper had to trim some off the ends to get it to line up to the wheel well but the shape i believe is the same

anybody else know anything about this?

88-89 and 90-91 are different.

I had an 89 Si front lip and tried to make it fit and it was too short, and the curves on the 89 were more sharp than the 91. The 91 has an overall more roundness to it with more smooth transitions on the corners.

I don't think you could do a universal 88-91 one that would look good on either or both.

Allright, I'll have to get a patern for the 90/91s. But back to the question... does everyone think this is a good height or should it be taller or shorter?

Ok i just went out an measured and I have 4" of clearance under my bumper to the jack so I would say that 2 an 3/4" would work just fine.

cool, thanks for measuring.

I have an 87 civic si lip on mine and it measures 1 3/4". It looks good cause it's straight down with no curves at all so it gives you a good idea of what measurements. I say anything around 2 - 2 1/2" would be best on there. And overlapping on 88-91 civics would look good but if for 90-91 crxs, dont' do it. Oh and here's a pic of mine to give a good idea of what I'm talking about.
