Well Im kinda new to dirt track racing and I need to know a few things. I work with a guy that has a late model and putting a cage in that car doesn't seem to hard to do. But I am looking for a bomber/charger car with a cage and no one seems to have one and I was wondering how I would go about putting a cage in. I have all access to torches and welders and I am experienced at welding but Im not to sure about how to put one in a car. Any feedback would be helpful. E-mail me at juiced_85@yahoo.com . Thanks fellas

easiest way is to buy a cage kit and follow the directions. just make sure to buy from a good company.

Is it put in by cutting the roof off? Or can you do it in the car?

If you buy a kit not assembled you can leave the roof on and weld it in piece by piece, but if you buy a cage that is already put together you would have to cut the roof off and drop it in.

Cut the roof off, it makes everything easier including stripping the extra metal out of it. The best part is being able to weld all the upper joints on top. You aren't building a show car. Build it safe. SLEEPY

lifting the body is fine if you have a chassis underneath. you'll have to chop the top when working on unibody cars if you expect to get good top welds. and just a hint - leave one set of door bars for last so that you can get in and out easier during construction. there a plenty of books out there describing how to build a cage. check out steve smith publishing on the net.

Sleepys right cut that roof off!We left one off til the car was almost ready for paint made everything a lot simpler.Up and including all the inside work.Just make sure you measure from frame to roof to put the cage as close to roof as possible.

Cut the roof off. It makes it easier to ensure those welds on the top hoop are good. You don't want to find out the hard way that you didn't have a good weld on one side of the roof halo.

Cut the roof off. If you happen to be taller than the average person, you can fit the cage to your height and patch the roof back on later. Safety first, Beauty second.

If you don't have a tubing bender buy the kit from a reputable dealer---just to cheap and it's not worth risking something that's been scabbed together. Make sure you use plenty of gussets and by all means cut the roof off.

you don't need to cut the roof off.
just tack weld main hoop/ roof hoop/ front pillar legs/ bottom sill rails all together, the knock out the two bottom sill rails and the main cage will drop enough for you to weld all the way around joints, if there is still not enough room, just knock out the front pillar legs and the two hoop pieces can be tilted downwards (sometimes even removed from car) for easy access.
i was shown this by an old guy who has built heaps of cars over the years.

NEVER cut the roof off. If you have ever seen a car flipping and the roof get thrown off you would know why. Weld the upper halo completely on the shop floor then when you put the rear uprights in the car you can just stand it up and it will fit perfectly. That is all the overhead welds you will have. The roof is an integral part of the chassis and the cage. You loose alot of strength when you cut it and you can't get it as strong as it was. Think safety all the way, not what is easier and or what you are too lazy to do.

Cut it off, the amount of strength you lose by cutting it off is negligible because the cage strengthens more than the roof. If your roof comes off during a roll over you did a terrible job reattaching it to the body. I have hung a few bodys on my car and now all the panels I fabricated including the roof just to make things line up easier.

if u cut the roof off yes it will be easier , BUT IF U DONT HAVE ANY SUPPORT CAGE IN A UNIDODY CAR IT WILL FLEX and when u put it all back together ur car will be twisted and will give u handling problems that u will never find ,so save the headache and keep the roof on

I am also building my first car, and thought I would just cut some squares out of the roof above any joints then patch them when done, as far as skinning out the roof, our class doesn't allow it. Really ***** cause I am building a 73 Chevelle and has a double layer roof.

chevell jjust do like i suggested above just jack the body up off the frame and burn the tops of the cage it's so much easier then patching a roof that will look like crap when your done i'm a firm believer in working smarter not harder and i have never found a roof that was easier to put back on and get lined up then hooking a cherry picker to the trunk lock and putting a floor jack on the floor pan
