Tools/materials:
Drill with metal bits
12mm wrench
12mm Socket
Needle Nose
Flat Head
Pen and paper
Sharpie
Ramps
Maybe a mallet
some washers
Beer
Friend to drink beer with and laugh at how ridiculously awesome this idea was
Band aid to cover your wound when you accidentally slip with the drill and hit your leg while the bit is still turning....

Step 1: Obtain a street sign legally (a stop sign happened to be almost the exact same size as my 07 plastic under tray).
If you can't do that then go spend $200+ on an aluminum skid plate.

Step 2: Take off the plastic under tray. If mother nature or a mother f*ckin pot hole ripped it off, skip to step 3. Use the flat head and needle nose to get the plastic pop connectors off. Use the 12mm socket to take of the other 5 bolts holding it on (at least for an 07 wagon there were 5).

Step 3: Reflect with a friend about how awesome this is and have a beer.

Step 4: Measure the distance between the holes that hold the under tray on (a pen and paper is handy for this).

Step 5: Take the sign and do a mock fit under the car to see where it will best line up with the holes. Have the friend hold it in place while you make a mark on the sign on the edge where the holes line up.

Step 6: Transfer the measurements onto the sign in line with your marks. Try to get it centered.

Step 7: Drill the holes out. Do a smaller pilot hole and then a bigger hole a hair bigger than the bolt diameter. Try not to wound yourself.

Step 8: Test fit the sign and make sure its not rubbing on anything. If it is rubbing, find the spot it's rubbing and mark it. Take the sign off and place a towel underneath it and on top of it. Use the mallet and hit the hell out of it until you put a nice divot in it. Repeat as necessary.

Step 9: Put the sign back up and put a couple of washers on there in between the bolt and sign to really hold it in place.

Now you are good to go

They were going to be scraped anyway.

I'll give you the skidplate title, but wouldn't go so far as to call it an 'under-spoiler'
definitely funny though

zeedeveel55 · « **Reply #3 on:** September 21, 2010, 06:34:32 AM »

I didn't know what to call it, but if you don't have one you will get worse gas mileage (maybe only a couple of mpgs),. It keeps the air from getting trapped under your car. Or. I just made it up and have no leg to stand on, and I should change the title.

Kavik · « **Reply #4 on:** September 21, 2010, 09:33:08 AM »

no, you have the right idea, definitely! I just meant without it going across the entire width it's not as functional as it could be for an undertray. It covers areas you don't want hitting things, but I would personally go wider is all

Maybe 3 yield signs welded together like this?

Hehe awesome dude.

We had a lot of fun, eh?

Kavik, you can't go too wide, you'll have tire interference. At maximum lock my tires will brush the edge slightly.

I'd say it's fair to call it an undertray, skid plate is a mild stretch and underspoiler is...optimistic.

Kavik · « **Reply #6 on:** September 21, 2010, 10:11:51 AM »

ahhhh, maybe it's the angle then. it didn't look like it went back far enough to interfere with the wheels......but I guess if I actually took 2 seconds to think about the shape of a stop sign, yeah, I guess it would go back a lot further then the rear edge of the bumper

i don't think you realize how big those signs actually are. a stop sign for a multi-lane road is 36" x 36". single lane is 30 x 30. yield signs are either 36" for single lane, 48" for multi-lane, or 60" for freeways on all sides of the triangle

so 2 sign lengths across the bottom would be a minimum of 6 feet.

if you come up with the 3 yield signs i'll weld them together free of charge!

P.S. I LOVE THIS POST, IT'S HILARIOUS!

Lolz. You know it's a skidplate when it forcefully removes a chunk of concrete from an Alpin Haus sidewalk and rolls away with barely a scratch(yup that was this dummy here) Woke them bishes up in the sales dept when I hit. Kinda surprised I didn't deploy the SRS that day

Kavik · « **Reply #15 on:** October 05, 2010, 01:24:36 PM »

you have to get a school zone sign, then mount it sideways underneath

zeedeveel55 · « **Reply #16 on:** December 20, 2010, 01:54:35 PM »

i have procured another stop sign.....

deadlydave · « **Reply #17 on:** December 20, 2010, 03:11:22 PM »

I kind of need a kitchen table.

You "Captured" another stop sign

That's three strikes each times two double multiplier .. It's all proportional to absolutely nothing..

Love this idea. Legs need to be made of struts or other car parts. Do it!
