while we are at it make sure to observe proper belt angles and spacing between the shoulder belt mounts or else they will break/break you/slip off http://www.mckenzies.com/v/vspfiles/...stall4cweb.jpg
note how the shoulder belts come together in back to keep them from sliping off the shouldershttp://www.schroth.com/installation-.../image_038.gif

In this picture from autopower the center eyebolt mount, while the bolt is correctly in tension the tab it goes through sure as hell isn't so thats crap the other two methods are acceptable. Wstar: I checked out the ones in your' journal and the braced and guseted the tabs pretty well, your belt adjusters are pretty close tour seats though it would be better if you could move them towards the bar more, and because you are pulling sideways on the Eye bolt make sure there is a large grade 8 hard washer under the tab and that the eye bolt is severly over rated because it is in at a bad angle check this out for proper use of an eye bolt, I used them at work all the time for lifting and this was part of the saftey course Eye Bolts That is unless those are just regular bolts under the belt holding the belt tabs down, can't see to well in your pick because the belt covers it.

Locking collars like this which are available from mcmaster are also a great idea if doing the belt around a bar method so the shoulder belts cant slide around and slip off.

And here we have an awesome roll bar with F'd up belt mounting

http://i664.photobucket.com/albums/v...0month/011.jpg and one done correctly minus the bolted together rear supports

also i just checked out the amuse harness bar and that thing is utter garbage for belt mounting, don't trust any harness bar that uses the stock brackets, or does the eyebolts with inserts like that, IF the TS bar is the same way shame on those fools. Gotta watch out just cuz it's F'n JDM doesn't mean it is worth ****. Held together with a hose clamp? You gotta be ******** me right?

Edit: OMFG that piece costs a grip, tell you what send me your' thousand bucks and i will fly out and smash your' face into your' steering wheel for you instead of going through all the trouble to install that bar.

mmm jdm hose clamps!!! lol


here's some cool stuff they have in japan:

NISMO racing harness NISMO Four-point, three inches, right seat, rotary buckle

Oh yeah thats not mounted to thiiin sheet metal, or way past the 10 degree shoulder belt angle or anything :sarcasm: Oh and the reason i make a big deal out of that 10 degree angle stuff is once you go past that the belts will actually compress your spine in an accident instead of just pulling you back in the seat.

I actually think I'm ok on the adjusters. There's not a lot of gap between my seatback and cage to begin with, but the adjusters are as far towards the cage-side as is reasonable and there's a bit of gap between them and the seatback. My shoulder-harness eyebolts do pull "sideways", but it's not quite at a 90, the plane tilts down in the back slightly. It's all grade-8 stuff though and put together by someone who's built (and seen wreck results from) many cages, I mostly trust the setup :)

It's cold and dark outside and the car's in the trailer right now, so I wasn't able to get very good pics, but here's a few:

Shoulder eyebolts from the top, with the excess-length rolls moved out of the way so you can see the bolts:

Underside of the same, w/ nut+washer (which I've since painted over - I only masked off the eyebolt top itself when painting):

And this is an example of my lower mounts (they all use the same basic welded-in round plate for the sub straps and belt straps, and the sub straps are down under the seat where they should be - this is one of the belt straps along the wall of the center console):

(And yeah, I just realized in that last pic that my lap belt on that side is rolled a little in the the clip - need to straighten that out!) :)

how do i know what rails and brackets to buy i have 2 vendors telling me different ones.

i trust one more than the other but just want to make sure.

What seats are you wanting to order?
Also, some seats can work with multiple rails it might just differ in the height of the seat.

For what seats?

figured coming from Nismo it'd be up to spec with safety...

Cheesemo makes mostly rice cosmetic enhancement parts for stock cars. Their race stuff is way different, you won't find that block on a nismo rc car. Thats like S-tune stuff and they only good stuff nismo makes is stuff for/off their race cars, like the rear diffs and bushings and stuff like that, the rest is for cosmetic purposes only.

installed seats today.
