Just an update:

I received the end clamps/covers and test fitted them.

As one can see, the -12AN on the right fits over the ARC silicone hoses to include the "hump" in the inlets/outlets of the tank. However, because of the size they rest against each other whereas the pictures look like there is a bit of wiggle room between each clamp/hose.

On the other hand, the -10AN on the left are too small to fit over the humps, only covering <5mm of the inlet/outlet. Unless the owners drilled out the openings of the clamps to fit, these wouldn't work.

I contacted the owner of the first picture (RJM strut brace) and he said he'd get back to me but that was earlier in the week and I've yet to receive a reply. I'm going to go ahead and order a small piece of the -10AN and -12AN hoses and test how they fit. That should be the final indicator on whether the -10AN should be drilled or to just use the -12AN.

Last update:

I received the -12/-10AN hoses and was able to test fit them. The -12AN fit over it, however as I mentioned before, with the hoses and clamps there is some contact between the pairs with the clamps/hoses installed; nothing serious, but still present. The -10AN, on the other hand, would require more work than necessary to included physically forcing it over the inlet/outlet to work.

Final result:
For anyone interested in using braided hoses/clamps with your ARC combo tank, you'll need the following parts:
-12AN hose clamps (8ct)
-12AN braided nylon/stainless steel hose pieces
*ARC tanks come included with 2x 16.5" and 2x 20.5" silicone hoses. I ordered 10ft so I can route it whichever way looks best. (make sure the hose is rated for oil or better)

Hope this helps and I'll post up pics whenever I have it all installed.

thanks for the write up. you just saved me a lot of head ache

love it man. I got mine but no Z :( . i think i would go the black and gold. sub to see the finish mate!!.

also if you jdm ninja runs out of stock. check out RHD japan

Actually, I was speaking with one of the guys in the builds section who informed me that, if you cut off those humps, you can run the -10AN hose/clamp setup.

Luckily I have friends in Japan so I'm able to get by without middle-men but thanks for the heads up!

Any one know what size the little lines for the cooling system are?
