ok... may not be a great question.

I want a relatively simple cage... something that is an all around type setup. nothing extravagent. Sounds like I need to do more research on the diff. cage requirements for the diff. types of racing.

I am building a strip/track/autoX/D1 car... sounds stupid but I want the car to be able to do whatever I want it to do ;) any suggestions will help. Thanks guys! awesome thread!

Assuming your car is not a vert or that it is gonna have an ET that requires a cage. Focus on the drifting cage rules. If your car will meet the ET requirement for a cage, try to design one that meets both requirements. Might be difficult to do. Just my .02

^nice. Im wndering if anyone has pictures of a caged vert. Full interior still, top still has to work like normal. Thinking about amking a new thread

Autopower bolt in cages are the bare minimum allowed. Yea its cheap, but is your life cheap ? Dont do it, save up and have a good cage done. Not only will you have real peace of mind but if done well, will add to your cars performance. Just my opinion

Here is how cheapy bolt-in roll cages can end up:
Notice in the last couple of photos, as the car is upside down, that the bolt in cage punched right thru the thin floor it was bolted to, and the roof collapsed

http://racersweb.com/forums/ford/153...-only-one.html

It takes time & experience to build a cage right, so that you don't end up like this

im loving all the cages. plus i think anyone that does X bars inthe doors should run gussets!

This is my cage that Afgmoto1978 and I have put together for myself.
Just need to finish the bars that will go through the firewall to the front strut towers and the cage its self will be complete.

These are nice!

Some more pictures of Dan's cage, front shock towers now have 6.5 & 8 degrees of caster adjustment in addition to the stock 4 degrees.

Couple of cage questions.

Bad idea to use 1.75 120 wall for the main hoop and 2 front bars to the a-pillars and use 1.75 95 wall for the rest of the cage? My bender only bends 1.75..

Also, why do some cage builders build a 1 peice halo for under the roof and weld in a-pillar bars to that halo, and most build bars that go right from the base of the a-pillar to the main hoop and conect them across the front of the windshield? Wouldn't the latter be better for rollover protection?

I love this thread.

very true well said! :nod: never knock the new kid on the block because everyone has something new to offer

Hi Guys,

I picked up a bolt in cage for my FC which I thought was going to be cold drawn steel.

When I picked it up from the seller (who had no idea about it and had bought it used himself) I was very surprised at how light it was!!

So, first thoughts from me was that it was chrome moly, but when I got it home and took all the padding off and looked at the welds, I thought maybe it is aluminum.

Anyway, how can I tell if this cage is chrome moly or aluminum??

I did the magnet test and the magnet does NOT stick to it.

Here are a few pics of the cage and welds...

That would be aluminum.

And I wouldn't trust anyone's life with it.

Here's mine :)

Any recommendations on a good fabricator in the San Fernando Valley (SoCal) to do a cage?
Preferably someone who is familiar with Mazdas.

Also, someone who knows SCCA, NHRA, etc. rollcage rulebook details...

A couple of pics from the cage i have made for my SC drag car

bare in mind some pics are older then others so some dont show all the bars in there currently.

Still got a bit to go but its getting there

First cage ive done to

1. IHRA says maximum 6"

2. weld in cages are far better.

3. theirs two types of bolt in cages i've seen ones that are welded at the joints then cut compressed and drilled so slide into the next bar, just an unnecessary weak point. the other uses tabs welded at the joints that match to a bushing end. these offer zero rigidity and often have less weld contact then welded cages. bolt in cages tend to be bolted to the floor. not to a frame rail which IHRA suggests. Bolt together cages are not permitted.

4. all bolt together cages are like that. See above

5. the more material you add the more weight you add. one diagonal bar is requires for lateral force. more cages use a rear cross brace in addition to the straight rear bars. this is a minimum required 6 point roll cage.

bolt in cages have got to be the biggest face palm ever
this is why

notice the cage poking through the floor.

Hi guys!

Very nice roll cages out there! I'm currently building up my fc3s TII...

I just wanted to ask if you know companies which sell a weld-in kit for my fc3s! I don't have a tube-notcher or tube-bender, so a pre-cuted/bended kit, ready to weld in, would be GREAT :)

i've used google but didn't came up with something useful :(

Theres a lot to consider in building/buying a cage. You should probably start a seperate thread that will get you more input.

check out all of our cages at www.retroracingteam.com
We have an IMSA GTU RX7, a GT3 RX3 and a new one on the way. We also have an ITA rx7, an EP RX2 and a Saker (don't ask, just look it up Saker racing on the internet). More pics to come, painting and building as fast as we can.

Jeff

how do you all come up with your designs?

Here are a few pictures of the cage I installed in my NASA Performance Touring FC

Most of the bars in at this point. Later changed the A pillar support.

anybody know that if to be NHRA legal that the rear down bars from the main hoop have to stay parallel?

i can't find anywhere stating they have to, but i don't want to weld them in for good if it will be illegal

thanks

zac

Man i been searching for a pic of a montego blue fd with a red cage. Does anyone have a pic

my australian tarmac rally/circuit racing FD fitted with a custom desing mild steel cage. it was built a few years ago now, so plan is to put some more bars and gussetting in shortly.

just a little something on how roll cages is a must. http://www.pirate4x4.com/forum/showthread.php?t=935863

Here's two pics of the cage in my FC RX-7 Race Car. Pretty simple but SCCA/NASA certified. Now to focus on the exterior lol :nod:

Very nice work

very nice to see your work again

Thanks, been very active but haven't done a lot of Mazdas nor visiting forums.
