Protecting bottom of front bumper

[Don Nguyen]

Has anyone on here put a metal plate, or something similar, on the bottom of their front bumpers, to protect it from scrapes/bumps/etc?

I think I've seen it on some cars before, but I can't seem to find the threads on them any longer.

I also want to see what kind of materials or methods people have used to mount the plates onto the bottom of their bumpers.

[Brian]

I think some people rivet metal to the bottom of their aero.


Whatever, I'll just break mine and run it over.

Who cares

[drftwerks]

mount ti to the bottom of the bumper, so you get cool white sparks when it hit the ground.

Well, I am definitely not going to be mounting it to the top of the bumper.

yeah who cares when you have Bn Sports lol.
i have little metal corners in the rear but still need to do sideskirts, helps alot, but mine could be a little bit cleaner, someone else did them.

Thanks for restating the obvious in your other post then, which is what I was trying to get to. What's the point of saying to mount it to the bottom, when it is obviously not going to be mounted anywhere else.

[idahotuner]

i am going to mount something to the bott0m of my bumper because it hangs down. with not much lip there cause of it being cut back for my intercooler.

i am going to run it all the way back to the oil pan and it will act as a skid plate too.

no way. low rider style. magnesium ftw:)

[brndck]

urethane. xenon lip ftw. /thread.

[Don Nguyen]

Trying to find a more universal method, especially for those who have different bumpers, etc.

What's a good method of cutting thin sheets of metal, jigsaw?

[NiSmo240luvR]

you could use a handheld grinder with a metal cutting wheel. the one i have uses 4 or 5 inch discs and cuts metal very nicely.

[kevtrinh]

what helps for a while is spraying a rubber coating on the bottom of the bumper.

Are you speaking of a diffuser? these are NOT to protect you from scraping your bumper these are for aerodynamic purposes.

he said "mount TI to the bottom"

not "mount IT to the bottom"

Ti = titanium. it makes awesome sparks.

That would have made a lot more sense if it was clearer, now I get it.

No I am not talking about a diffuser. My bumper actually already has one built into it, but I want to bolt something to the bottom of it, to protect it from simple scrapes eating away at it over time.

My bad on those previous comment regarding it then, I thought it was just another guy trying to be a smart ass with some stupid post.

[lflkajfj12123]

can't you have some ingenuity?

just get some sheet metal

take a marker trace your bumper and make a cut out

everyone needs their hand held

[Fries]

Fuck zilvia period. Granted it was a somewhat silly question but for someone who may not of ever done something like this, it is a legitimate question. [And isnt really searchable: "Metal POS stapled to the bottom of cars"]

But seriously your replys state that you think you know what you want to do. Wouldnt a better question be, Zilvia how do I use google inorder to find out how to cut sheet metal to put on the bottom of my car.

Good luck.

That diffuser is way fresh! id never seen something like that before, custom im guessing, i need to make something like that, not for aero purposes but for oil pan protection or my Greddy pan will take a beating. when i get bak from vaca i will start on mine. sheet metal and cutting wheel here we go!... maybe plasma torch. thanks lol

[lflkajfj12123]

they have like featured diffusers in option2 magazine ALL the time

i never read it, im not with the option times lol. i hardly watch the videos.

I didn't think posting a question would cause so much problems. I figured, why not, it is a discussion board after all, at least that's what I thought. Tried searching all of the forums I was on, and on google, couldn't find anything that really helped (maybe one or two threads, with vague descriptions).

Of course I have a general idea of what to do, or what I am talking about, that's how I got going in this direction in the first place.

It is simple to just cut up a piece of metal and put it under the car/bumper. However, I am not trying to mickey mouse stuff up, but at the same time, I am not talking about spending hundreds/thousands of dollars, trying to do this little project.

I wanted to post this here, in case someone had experience with something like this, or had done it in the past, which they could then provide some input on it. IE, other possible mounting techniques, possibly different materials to use (lighter/stronger/etc), what works or what doesn't, etc.

Putting something on and have it look/work good for a couple of days may work for some people, but I am looking for something that will last a little bit longer than that.

Not trying to make this post sound like an attack, but I am just tired of posters jerking other posts/threads around with their posts. Some people need to get off of their high horse and help out, or just don't post at all. All this negativity ruins forums, imo.

Super worked up? I thought he was trying to make a useless comment/post, which your posts certainly seem to be.

I even took back what I said, and admitted that what I did was wrong, especially since I mistook his post for something else.

[jt1583]

damn that s15 has a nice one.

[singlecamslam]

I use a "DO NOT ENTER" sign i got from the street.

[Def]

Everything that has been posted up as a "diffuser" is actually a splitter... Diffusers are at the back of the car.

As for metal, any aluminum 0.0625"(16 Ga) thick or thicker will work just fine. Cut it to shape and pop rivet it in. Steel will last longer since it is harder, weigh more, and rust where it gets scraped up(assuming you paint it to start with) - so not the best thing to use.

[infinitexsound]

yeah thats how race cars do it... they tend to make a template out of cardboard paper.. from the shape of the bumper.. step it out about 1.5" then extend it to about where the the x member is.... then they pop rivet it there... and pop rivet it to the bumper...use the metal washers for backing on cf and fiberglas....acts as a skid plate and helps with aero.... id run .090 tho just because it can handle a beating more then .060...... u can get advance and make it out of cf.... which is pretty cake but expensive.... steel is heavy f* that...

faccckkkkk that looks wayyy coool.

im trying to decide what diffuser to get.

of course it will be there to look cool, not to have better aerodynamics or whatever the shit its supposed to do on actual functional cars and shit.

and shit.

calvin wan was using plywood at one point, and he's not exactly a broke drifter.

seemed to work ok for him

damn pretty sick diffuser any 1 know where i can get my self 1 for the s15 front end

[Def]

It's a splitter people!!! SPLITTER! Diffusers go in the REAR of the car. You guys must have been hanging out on ebay too much where they call everything a diffuser...


Plywood and fiberglass is a great way to build one, and it's pretty cheap so if you trash it no big deal. I'll probably do the same when I thing about building a SPLITTER.

Great, the next drift trend because "faccckkkkk that looks wayyy coool."

and use it for looks instead of the real purpose...

sounds like the typical ricer

i deeply apologize that i will be using the M sports diffuser for something other than its original purpose.

because, you know, I'm sure M sports designed their front splitter for a reason other than to look cool.

[FIlthy 24O]

is that a 14 with flip ups?they look good sometimes...took me a while to see it...sneaky....

[infinitexsound]

air diffusers are great for the extra mph... i pretty sure it helps to relieve air pressure under the car.... it looks cool... but its not pratical with street cars...

[Don Nguyen]

How come they're not practical for street cars?

[IIIXziuR]

Its always breaks....no matter what.

It always does.

[blueshark123]

i loved sasha's s14 diffuser shit was ballin

[infinitexsound]

because it's a street car, not a race car....... are you gonna drive you car over 100mph daily everywhere you go? i noticed mitsubishi implemented a diffuser to the evo... but its nothing so drastic... where it hangs 2-3" off the ground...but whats the point of having it if your never going to use it? to look cool?
for a street car id rather have cf parts that i molded myself.... to save weight... i can see that making more of a difference.... or even running nitrogen in my tires with the correct tire pressure... that would definetly save me some gas money...

[ayuaddict]

omg.

on 90% of S13/14s they are there solely to look cool.

and its not gonna look cool 2-3" off the ground.

my bumper is 2-3" off the ground.

thats where the diffuser comes into play.

now you can have your front bumper 1-2" off the ground.

yes, it will crack, yes, it will fall off.

yes, you can deal with it, yes, you can buy another one.

no, dopeness is not cheap.

Why the fuck is everyone off topic. All the OP wants is an idea of how to keep his front bumper from scraping to death.

Uhh you need to think before you speak. Because you're spewing filth.

A diffuser is a shaped section of a car's underbody which improves the car's aerodynamic properties.

Those on the front bumper are canards. They attach to the front spoiler/bumper of a car for the purposes of modifying the aerodynamic characteristics of the car in a modest way.

Buy sheet metal at any local hardware store. Lowes or Home Depot. Get a large enough cardboard you will use to trace the out lining bottom of your bumper. Line that cardboard on the sheet metal and cut to size. Use a handheld grinder with a metal cutting wheel (as stated before) I have one and is useful for many other things as well. Either connect the Beatrush underpanel with zipties or rivet both pieces together. Ziptie or rivet entire piece to under side of bumper.

Create your own rendition from this idea. Any other ideas or constructive advice pass it to this guy so he can get going on this. There are so many ways of fabricating a SPLITTER. Use your imagination. You don't have to always purchase a ready made one.

[!Zar!]

That's a Rear Diffuser.

Even says it in the title.

Come on people.

This is simple stuff.

A splitter generates downforce on the front of a car by creating pressure differentials. Actually a splitter produces a "downward force". It is not technically termed "downforce" unless the downward force is large enough to overcome the "upward" force caused by lift. But that is really just semantics.

Just cause it doesn't work, doesn't make it impractical. Even then, if I was to make a skid plate, it wouldn't be hanging that much lower (considering the sheet of metal would be around 1/16" thick).

Yea, if you get a splitter that's like 2-3" thick, it'll make it closer to the ground, but that's not what I am trying to make.

You are almost contradicting yourself with your 2nd comment. CF parts and nitrogen on a street car? Are you trying to save weight with the nitrogen in your tires?

Thanks for the advice.

One of my main concerns, I guess you can call it, is how big I wanted to make it. I definitely wanted it to go across the entire front lip of the bumper, but how far back did I want it to go, was my dilemma.

I wasn't sure if the back part of my splitter/under panel was going to really need the protection there, since I am mainly just to protect the bumper from everyday scratches wearing it away, etc. However, I figured, since I am already there, I could just have it extend that far back. My only concern would be, if I was to have it go that far back, it could end up creating unecessary stress on the fiberglass bumper.

I also wasn't sure how I wanted to mount it to the bumper exactly. I ended up making 3 sections, one main center section, and two outer sections, on the very ends of the bumper. The main center section, I have 6-8 bolts holding it to the bumper, to spread out the load. For the two smaller outer sections, I just used very strong double sided tape. I figure that area would be getting the most abuse, getting in and out of driveways at angles, etc. Since that was the case, I didn't want to have the edge of the plate catch on the ground, and rip a huge hole in the bumper, if I was to use a screw to hold it on. I think I made the right choice, but only time will tell.

[infinitexsound]

i was trying to be funny implemented sarcasm. zilvia is so serious now.... wow...i see that your quoting numerous ppl in different posts... are you being funny too eh hahahahha...

[atom]

How did this thread get so big without someone mentioning composite aluminum sheets like alumalite or dibond? I thought thats what all the cool kids are using nowadays to make their splitters.

[CKAMC]

I have seen acrylic work as well

there is more than one way/reason a person might do this

1, front splitter not only protects the front bumper from scrapes, along with serving as a aerodynamic function like canards, does not extend as far back as a front diffuser or skid plate. Most are made of CF or ABS plastic/urethane and consist as either an add-on to canards or as one full piece designed for specific bumpers.

2, skid plate was originally intended to protect the engine bay, its components from random crap (ie rocks), some have cut outs for the oil pan if it wasn't weak to being banged up. Made of acrylic or sheet metal

3, front diffuser is pretty much just like top secret s15, its functions have already been listed off, however some put slits in to help with cooling, but again most are designed for high speed aerodynamics. Some feature front splitter into their design. Made from CF to plywood

anyways there you have it, seen some molded while others get bolted... if you don't mind seeing your car run over your hard work then yeah you can use double sided tape(I don't always trust the shit even with rear spoilers)

not too hard to make a template, but for final production sake you may not be the person creating the CF/ABS piece.
