Does anyone know a company that makes a weld in/bolt in roll cage for our cars?

 

Autopower has both.

 

Oh sweet, anybody got pics of one in there car?

 

Check the race section...

 

Moroso, trim to fit and weld in. I also installed the door bars with the hinge kit.

 

I'd recommend a custom cage. Find the SCCA region in your area and find out who handles club racing. Tell them what you are looking for (someone to do a cage for you). There is a good chance they will have a few names for you.
One thing about doing a cage in an FB is head room for the driver. Sit in your car without a cage and see how little room there is between your head and the area above the door window. Then subtract the dia of the cage tubing, 1 1/2" or 1 3/4", and then another 1 1/2" for the thickness of your helmet then another inch for the padding you will need. Your head will probably be touching the bar. Ask the person you find what they do to help this. I usually slice the metal(inside) front to back above the door and hammer it back to the roof skin, this will give you about an extra 1 1/2" of space. You may need to install your seat a little tilted to the inside.

 

Ummm, i think peyton engineering or performance.

 

mmmmm lookin good.
I would really like to get a roll bar, but being 6'2" I have no idea how it will work with the stock seats, and my fat butt.

 

A roll bar shouldn't be a big deal if you plan for a tall person etc. A cage can be difficult but I had someone 6'5" in my old car(racecar rental) so it can be done. The pics above aren't considered a cage, just a roll bar.

 

Its all well and good for a race car, there are compromises you can make with a seat/comfort/and long term rideability. I want a bar for my street/auto-x car.
(I know the argument against bars on the street, so lets not go there)
But for a street car, were the seat needs to have a measure of comfort it gets REALLY difficult to make room for me.

 

 

^^^uhh isn't that a bad idea to strap your belts to the floor.

 

i assume they are bolted through the floor to a load bearing frame support.

going straight down behind the seats is a bad idea because the steeper the angle of the shoulder belts the less effective they are at holding you back.

I would hope at least they are attached to a support that can handle a load. I read a thread though that you are not supposed to attach the belts at a lower point then the rear seat height.

Let me see if I can find the thread...

 

The Autopower is a nice piece,although the factory paint sucks.I had mine powdercoated to match the interior color.It doesnt interfere at all with your seating position and its tucked back enough that it'd be hard to strike it with your head.

I could not find the thread that I was thinking of but this lightly touches on it.

Also looking at steve's cage this is how it should look IIRC

 

When do you consider it a bar or cage? Is the front hoop the deciding factor?

I've seen bars on the street, but never a full cage.

As far as a bar on the street, I'd be allright. I think I don't want a cage on the street though.

 

^^^^I agree

 

So where do you get hinge kits for the side door bars?

 

Moroso, from thier catalouge. They are made by Competition Engineering.

 

Whether you go with a roll bar or a full cage, you should decide which style you want -- SCCA (road race) or drag race. The SCCA style will have the diagonal that runs from the driver's head down to the passengers butt. This is usually accompanied by a seat belt bar that runs cross-car at shoulder belt height, and lastly, by the rear diagonals that angle down from the top of the cage to the rear floor. I don't know much about the drag race style, but the ones that have the two shorter diagonals aren't SCCA legal. The reason you want to get this right from the start is that many cars progress from a roll bar to a full cage, and it's easier if the back half of your cage is correct.

 

Did you try CP Racing in Canada? They make a nice piece. Check out their website. www.cpracing.ca

 

Steve, which Autopower model is that? It looks like the "race" one, but I don't know what the difference between the ERW, DOM, and 2" ones. I'm thinking that's what I'm going to get. Also, did those harness hooks come on it or did you put them on yourself?

From your picture it looks like you have to get a bit creative with the passenger storage bin =P

 

first off, never mount belts to sheetmetal, mount to cage, frame rail or something reinforced that won't shear if it sees 4000lbs of force. Second, belts should be mounted at a 10° maximum incline from the shoulder point, see drawing. Injury to your spine (compression fractures if memory serves) is very possible if you deviate from the 10°.

 

Ok for everyone here, I didn't do that. I bought the car like that with everything in there like it is.
