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!

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..

RyanWest · 08-19-2017, 04:52 PM

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.

You have pictures on how it's mounted.

RyanWest · 08-21-2017, 05:19 PM

Trying to attach pictures but wont allow me.

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

Also the top metal piece is not thin IMO.

Ok, I see how it's mounted now.

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

Robispec Harness Bar Install

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.

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

Rusty,

This harness bar does not attach to anything in these pictures.

The bar comes with a drop bolt that goes through the metal plating. Essentially getting two contact points for security.

It does not attach to the cross bar!

I think we get it, you like the MA bar. I do too..... Just not enough to spend $650 on it.
