Plate hole... The JDM bumper has a large hole where on the OEM Japanese models the plate mount comes through the bumper and the plate covers the hole and mount. However because the US plates are narrower than Japanese and Euro plates, the hole is typically exposed on the sides of the plate. This is why all US Evos with JDM bumpers typically have plate covers "powered by Greddy" "Mark Mitsubishi" and the like to make the plate wider and try and hide the exposed edges of the hole on the sides of the plate.

Yes it is alot to do, but I don't like to "rig" something, or do it anything less than 10/10ths. This type of attention to detail is what makes my projects last 20x longer than others to complete :-(.

OK, so I took pictures, and I cannot believe what a pain it is to take pics at night with a POS digital camera...

Now, just a note, my hardware store didn't have black oxide rivets, so I had to use plain alluminum ones, I have the black rivets on order, but they won't be here till later this week... once they are here, I'll drill the silver ones and replace them

So here's a picture of the plate pannel on the car


Here's a close up of the carbon fiber pannel


Here's the way the LEDs look on the plate


Here's a close up of the LEDs on the pannel


Flame away guys! LOL

the stock crash beam is only a 5MPH crash bumper...japan doesnt even use these...its a us spec thing....you can take your stock one and cut out the section between the beam and where it mounts..thats what most people do....

I made it. It's 6 layers of 1x1 carbon fiber (I was out of 2x2 twill), made on a glass mold in my spare time. $3 worth of carbon fiber, $2 worth of clear epoxy resin, $5 for a sheet of glass, $2 worth of clay, 2 cents worth of mold release wax, and about 2 hours worth of time doing the layup and trim-out.

Yes, it does, you're just not looking close enough. Here's the same picture with the holes circled in red. Also see how the factory lights are exposed when viewed from the rear. at night the lights will look like small reverse lights

No... the foam in the rear bumper is a 5MPH crash item. US law states that a vehicle must be able to withstand a 5MPH unloaded impact (meaning that the vehicle is rolling at 5MPH without any additional force, only it's momentum) into a 10" round pole without sustaining structural damage. The crash beam we have is for the 30MPH offset impact test.

Also in Japan remember that the laws are designed to make cars disposable items so that it helps keep the auto industry going. Therefore JDM cars use thinner sheetmetal, less underproofing and so on. once a car reaches 5 years, taxes increase on the car dramaticly to a point where it's cheaper to buy a new car than to register a used car. This is why we get such cheap JDM half cuts and engines with "less than 30K miles". The inspection process is called "Shaken" and nearly all 5+ year old cars fail

As new vehicles are designed to be used for such a short time, if a 3 yr old car is totaled from a small rear impact, it's not such a loss as there was only a few years left on the life of the vehicle anyways.

The sheet metal in the back of the Evo is extremely thin and flimsy. The crash beam is designed to spread a center rear impact to the box sections of the unibody (the strongest parts) so that the vehicle is pushed forward rather than slice through that thin metal.

I've cut cars apart, I've designed chassis, I've also been first responder at accident scenes. I know the damage that accidents cause, and I know how cars are put together. There is NO WAY IN H*LL that I would allow someone I cared about to be in a car with compromised safety... especially structural integrety.

When I do finally get m JDM rear, I will be keeping the stock crash bar.

Any of you guys think of what insurance might say when they go to look at your car and there is no crash bar there...I can see them denying you coverage very easily.

Not worth it IMO to not have the crash bar when there IS a solution that is fairly cheap.
