Harness Bar Installed. :)
 

Pretty easy install. Stock seat belts removed.

Who's bar?

Doesn't appear to be either the MA Motorsports or TrackArt bars... OP, do you have better pictures of the mounting points where the seatbelts used to be? Also, why did you end up removing the stock seat belts?

PLease post more pics and where did you get this bar?

You may want to retain the oem seat bealt for dd the car because buckling and unbuckling a seat belt harness is a pain in the but!

Also they are not really meant to be used with air bags and should be coupled with a head and neck restraint.

But how will all my friends know I am 2Furious?

Because Takata make a 4 point street legal racing harness! :rolleyes:

...as did Schroth (with ASM) :ughdance:

Negative. This is not a DD. :P

Braum Seats going in + 4 point harness. :)

Dude, I have that same bar, and I'm trying to install it but to no avail. How did you bolt it into the belt socket? Just the bolt? Did you use the fat washer that comes in the oem belt bolt?

I took the fat washer out of the OEM belt and used it. Fits perfect. :)

I see from the picture you removed your oem seat belts. I'm wondering, when you removed the retractors, what did you do with the sensor cable? Are you getting an airbag warning without the retractors?

I tucked everything behind the plastic panels. Not sure what lights are on yet but Ill focus on that later.

Are you completely confident that mounting to the stock hollow cross brace is going to hold you in your seat safely? The seat belt mounting holes are meant to restrain you but that rear cross brace was engineered to match its name.

At most I trust the MA Motorsports harness bar for a street application since they actually mount frame/body bolt. I don't like to risk safety.

Good luck!

That stock cross bar WILL NOT hold you! :icon14: It's just thin sheet aluminum tube that will crumple with about 15 lbs of force. I have one sitting in my attic. I replaced with with a Robbyspec bar.

Who are you referring to? There is no mention of anyone mounting anything to the stock cross brace in this thread..

Rusty, he's just hooking a harness bar the the points where the upper seatbelt mounts are. It's a pretty reasonable setup in that respect, the bar is pretty sturdy looking. For me I wouldn't use any harness with out a helmet and hans, to high of a risk of you snapping your spine and becoming paralyzed or dead since there is no give with a harness like there is with a OEM seat belt. But each to his own.

Guys this Harness bar does attach to the stock cross bar. It uses a L bracket. This thing is seriously connected and firm! I will be using Braum Harness Straps. Ill post more pics when the seats are in.

I just put a warning out. ;) Having replaced that aluminum piece of bling with a different bar. I know how it's made, and how it's mounted. I just don't want anyone to trust their life with it.

I don't think you understand how the L bracket connects to the stock harness bar.

This

I totally understand, most people don't grasp that even in a 30mph accident with a stationary object your body experiences tons of force even with all the modern enhancements. The sheet metal in non structural elements will bend and tear like paper when subjected to hundreds of pounds of force.

You have pictures on how it's mounted. ;)

You do realize there is a long drop screw. It does not bolt to the top of the metal I think you are referring to.

Also the top metal piece is not thin IMO.

Trying to attach pictures but wont allow me. :(

There are 4 points that secure the harness bar into place.

Here are the two best pictures I could find of how the Cipher bar is mounted...

Ok, I see how it's mounted now.

Here's my thread on installing the Robispec bar. It replaces the cheezy cross bar.

I've gotten into 2 wrecks, 1 front end and 1 back end. Both times I was using Schroth 4 point harnesses and never had an issue. The stock brace bar held just fine even with 2 180 lb people

How fast were you and/or the offending cars going in these wrecks?

Either way, I'd say you're more lucky than anything.

First wreck was sliding into a guardrail going about 30 mph or so. 15k worth of damage. Due to them being harnesses, we had a slight jolt. If we were using stock seatbelts we definitely would have had whiplash.

2nd wreck was last monday. Guy rearended me going about 35/40. 8k worth of damage, sore neck the next day but thats it.

No damage to the brace bar either times.

That aluminum bar is just a shell that goes around an inner thick bar if I am not mistaken. Never any bending at all.

If I could even find a better bar to replace it I would. But both the Amuse and Robispec bars were almost impossible to find, and close to 1k if I recall correctly. Seems a bit crazy to me. And I feel safer with the stock bar than those thin "harness bars" that attach with L brackets

Wrong! The aluminum bar you see is it. There is no inner bar. Additionally, unlike the Robispec bar which bolts directly to the chassis, the OE bar is held in place by flimsy sheet metal brackets.

And the reason harness bars regardless of design cost so much; legal LIABILITY. All it takes is one lawsuit, regardless of how baseless it is, to destroy a company.

The factory cross bar weights 1.5 lbs with brackets. It's .114" or 2.89mm thick. You can see how thick the brackets are. :eek:

Aluminum is strong enough right? , JK but seeing this now semi worries me. Car is still in the shop so I have about a week to find a replacement. Since we are already in the thread, any suggestions for a cheap strong bar, and also a more expensive better quality bar? I need something I can buy today, not contact 10 different people and try to get custom made

Honestly, unless you're going all out with a full cage, appropriate seats, 6 point harnesses and a HANS, you're better off with the OEM restraints and airbags. Nissan has a lot more on the line than Bob's Discount Harness Bars & Chicken, so they over engineer everything and crash test the hell out of it. Also, "cheap" should not be a concern when dealing with brakes, safety systems, whisky or condoms.

Belts on the street, harnesses on the track.

You got lucky twice. Most people don't get a third try at it.

I have both proper seats and proper belts. No reason for 6 point because the 4 points I have are anti-sub. I understand that roll cage is usually needed in case of the roof collapsing but this is a street car not a track car. I'm noy rolling this thing or even remotely close. I just like how the harnesses keep you in the seat. Cipher bar looks good enough.

Yeah, aluminum is strong enough IF it's designed for the application. In this case. It's not. MA Motorsports makes a good harness bar. I've seen their bar at ZDayZ this year. Talk to Daelen. He's a good guy. Tell him Russ sent you.

With this set-up. You keep the stock cross bar. And you have better angles with the belts.
