How much of a pain in the ass is it to get in and out with the side bar of the cage? I am 6ft, 220#.

It's actually EASIER than without. You can use the sidebar to push yourself up when getting out of the car ...

Could/would you make one with the angled side-bars that are removable...so you can take them out for street driving? Would it still be stiff? Also would it be beneficial to add a Perry or Engman long stiff kit along with this?

Man I need a new job so I can afford this! I'll do some figuring and get back to you.

Nathan,

We might be able to do something with these.

It'll add some cost though and sacrifice some rigidity, and probably aren't smart for actual track safety.

Mark,
Get a hold of Elliot Cannon. His door bar in the yellow car is an outstanding modification that can make these much easier to get in and out of with a street car.

Nice idea Mark. The GT bar is a nice looking design.

McMark: waddya think of this? The 914T currently has the Brad Mayeur heavy duty outer long kit installed. It was not installed to repair ANY structural rust or rot to the longs, I added it to a solid car to keep it that way. IF I was to add your rollbar kit, would the car be stiff enough that I could remove the box sections that run between the center tunnel and the outer sill that the seats mount to? I've been thinking I'd like to put some after market seats in, and retain the seat slider/tilt system that is in the car now, but would need to mount it flat to the floor to fit a non-914 seat. In my car pics you can see the OMP seat I have in the car on the driver side. I made some flat adapters to fit the seat to the oem sliders, and when I'm in the car with my helmet on, I am above the windshield with the top of the helmet. I'd like to put in 2 matching seats, and mount them lower. I was thinking of a full autopower style cage, but had concerns on the street. Your cage could be one solution to consider.

What does anyone think? With Brads outer kit already installed, and if I were to add McMarks rollbar, would adding the engman kit add much more strength? I could easily have a weld-a-thon one weekend and do the engman and the roll bar...

...and, what would you need to do for a replacement back pad- go over the metal firewall directly, or leave the insulation panel glued on and go over that?

Does it require use of a racing harness in place of stock seat belts?

Dave,

I think the cross-bar under the seats is of little structural value. I think it's partly to provide a support for the seats, and partly to brace the floor pan. Check out post #50 of this thread where horizontally-opposed modified the beam for the same purpose as you. If I were doing the modification, I would go this route. That way the floor pan retains some support. Moving the beam forward would also accomplish the same.

You cannot lower the seat and keep the tilt feature. The 'teeth' that lock the height adjustment are part of what makes the cross-beam so tall. To get height adjustment you would need to fabricate something custom. I would also think that you'll get the best results by getting rid of the seat hinges.

I think this GT half-cage would marginalize the Engman kit. If you're looking for every last scrap of stiffening, then you could do both.

Because you can't use the stock backpad, a bare firewall or a carpeted firewall would be the only solution.

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)

Hi McMark,

Thanks so much for reproducing these. I'm on a never-ending quest to make our (the 914-6 is Tricia's) GT clone a really accurate clone!

Attached Image

I'm investigating my 'secret' 914 funds now to see if I can order one without being kicked out of the house... (I've already ordered the GT headlight kit.. shhhhhhh : )

Just a quick question, which is somewhat OT from the originality. Didn't brant have a post about the safety factor of a side to side bar behind the seats? I thought he promoted the safety of a side to side bar with a T-Bone in the drivers door?

I'm not proposing you add these, but just want to respond to the previous posts and offer the thought that they are functional and do add some safety.

Thanks again for offering this exciting GT product! I'll be in touch

Greg

I think in this case, if all-inclusive safety is your #1 goal, this may not be the product for you. I'm making this available as a replica GT part for 'originality' purposes, as well as a stiffening benefit. There is obviously a safety benefit to any roll bar/cage, but this setup is less about safety than some of the others.

That being said, I would love to see a link to the post you're thinking of. I'm always eager to learn, and other bolt in/weld in cages may be in my future. (IMG:style_emoticons/default/wink.gif)

That looks a whole lot like a Safety Devices bolt in roll cage for a 914. I bought one years ago with the idea of having it welded in. Instead I used it for a pattern and made my own full cage from the pattern and sold the bolt in cage....I did not use the plate on the firewall...did something better.....

The one I had was from the mid 90's. They may have changed the design since.... (IMG:style_emoticons/default/dry.gif)

SCCA requires a full diagonal to run from the top corner to a bottom corner in order to be legal for Time Trial, you might see if you can convince them that these are just as strong and get them allowed. Otherwise they aren't SCCA legal unless you do a diagonal on the rearward down bars, which will totally ruin your goal of having a replica bar.

I don't recommend any further stiffening kits with these. Added weight that won't be necessary.

Here's the way mine was done. Instead of the flat piece that goes on the firewall we put in a piece through the firewall connecting all four of the rear brace bars. I would think that would pass for a top to bottom corner bar??? (IMG:style_emoticons/default/idea.gif)
