The safety devices company have a couple of different styles.
and their Euro sold version of a bolt in kit, did have the fire-wall V style of mount similar to the Mark's design.
I used to have one too.


I think its VERY nice looking

this is taking the thread off topic, but I personally feel the seat mount bar does provide structural rigidity and structural boxing to the chassis.
I cut mine out once on my black car, but within months added it back.
I think there is some structural purpose and more importantly I think it is a big safety factor for side impact.

I also modified my safety devices bar to add a cross brace down low behind the seats from side to side.

I have seen a 914 hit in a T bone accident on the race track
the car was hit at the driver side seat area and moved inward about 12 inches. This is scary, because your shoulder is only about 6 inches from the outside shell of the door.

imagine taking a direct metal impact into your shoulder from a 3000lb moving car?

so I think the rear side to side bar is important for safety or racing, and the seat mount cross brace is a small nod towards side impact safety from the factory.

The factory long moves inward very easily in a metal to metal contact.

buy a different seat if you need head room
the ultra shield seat will mount nicely on the floor behind the stock cross brace.... my old scheel seats mounted on the stock sliders/stock cross brace and were low also.

2cents
nice roll bar Mark!

I don't believe that Safety Devices is still making their Bar with the V-Brace

Mark, if I already didn't have one to put in my GT, I would buy one of yours.

I have the Safety Devices Cage in mine. It has the firewall mount. I think they will reproduce on special order.

Thanks for your $0.02 Brant. I was considering this but I'm afraid it will make the car too uncomfortable for longer drives and I'm worried about leg room as well as head room - I guess I could always use cardboard seats. (IMG:style_emoticons/default/laugh.gif)

I have no idea where the hardware for this came from but it works pretty good. I'll sell anyone the side bars for $20,000. What the hell, I'll even throw in the car. (IMG:style_emoticons/default/av-943.gif)

structural integrity anyone.

I talked to Bob @ Stable Energies today to buy some parts for a customer today and Safety Devices still makes the V-Brace for them, even though it is not on the Safety Devices WebSite

Quite a bit more than McMarks

Highly interested, I'll be giving you a call to discuss soon.

Mark, your idea for the roll cage looks awesome. My question to you, for us older guys who have a little tougher time getting in and out of these cars, could this side bar be an option? what are your thoughts and concerns?

Thank you (IMG:style_emoticons/default/smile.gif)

A bar like that would be do-able. It'll lose some rigity, but I can't say how much. May not be noticeable at all.

Seems like adding a short tube, elbow to crotch, would make a big difference in that example. The bend with no support is sketchy. Wait, the more I look at that, the more it bugs me. The bend is bad. It would be better to make the side tube straight and connect it lower to the rollbar than bend it like that. Ugh, we are venturing outside best design standards. Bends are for hoops. Tubes between pillars should be straight and triangulate. Hey I'm a poet and don't know it.

Here's what Tony did on my cage. Ignore the temp bracing ...

I'd order one, but I think I am going to wait for AA to offer it for $5 cheaper in a "What's New" thread

Should expect to see one real soon...........

Could this work to replace my "missing" targa bar (IMG:style_emoticons/default/idea.gif) ?
