Put some pool noodles on the beams so I don't break my head if I'm off track driving with out a Helmet and I get side swiped

Nice! Any chance of getting some closeups of the welds? I like to stroke my own ego by comparing other peoples to mine
NissanEgg: (2013-04-29 01:07:15)
Why not tie into the suspension pickup points in the rear? Or further up to the firewall?
aceman85turbo: (2013-04-29 02:08:34)
seam welded tube with nasty mig welds and incorrect pickup points? also looks like incomplete fusion on the plates.
There is a good chance that cage will actually cause more damage to the driver than no cage at all, post some close ups on the welds.
G-E: (2013-04-29 03:24:38)
I thought for all classes of racing you're supposed to use DOM tubing? And that looks like half a cage, the main hoop should have at least tied into the rear strut towers instead of that weird down bar behind the seat…
It almost looks like it was done by someone who hates symmetry actually haha, is there an opposite to OCD?
Careless: (2013-04-29 03:41:09)
guys. it's ok. the same guy who welded this cage also has a custom car shop that specializes in auto body and obnoxiously styled lifted trucks and donks with bitchin sound systems. he knows all about cage building.
lol. it's pretty obvious this car is just a hoon slut, everything about it screams "i really want it to blow up without regard for my safety, as long as I have fun". a cage that won't passed tech is not surprising, if not predictable.
jesus94p: (2013-04-29 03:49:47)
I don't know whats worst, this or the front suspension setup…
G-E: (2013-04-29 06:30:57)
Could be the mylar on the roof… is that some sort of anti-friction trick for the helmet to rub on?
mazdaspeed3: (2013-04-29 18:34:36)
Try not to be too jealous lol

mazdaspeed3: (2013-04-29 18:36:56)
cage was built to formula d specs and regulations lol it will pass tech in any drift event
mazdaspeed3: (2013-04-29 18:37:42)
my next race is may 12th ill let you know how well it passes lol
mazdaspeed3: (2013-04-29 18:38:56)
idk about other rac specs but for drifting events it can be mild steel or chromoly , mine is mild steel
mazdaspeed3: (2013-04-29 18:42:40)
are you serious ? lol i bought $280 takata seat belt harness , $1,000 bride seats , anazy lol razy lol d a roll cage , your crazy if you think safety is not my number 1 goal in this car i could have spent all that money building the engine but i spent it on safety gear

stufferton: (2013-04-29 20:16:31)
I think what they are trying to point out is that while all the OTHER safety gear is fine (no one has mentioned it being a bad idea) the cage is very obviously 3rd rate craftmanship. While a 'professional' shop may have done the work, roll cages and racing products are certainly NOT their cup o' tea. It's on par with having an engine building shop do your body work and paint. Professional shop, but not what they do.
Would have been better off going to a shop that builds dune buggies or rock crawlers IMO.
G-E: (2013-04-29 22:13:16)
Safety is #1????
You cut and welded struts from a different car with different characteristics with no inner sleeve for extra strength at the weld joint as far as I can tell
You have a cage made of weld-seam tubing, designed by someone who doesn't do cages for a living, won't pass safety at any sanctioned event, in a very strange configuration
BUT you have awesomely expensive seats....
G-E: (2013-04-29 22:18:44)
I'm even going to help you by linking a pdf to read
http://www.camsmanual.com.au/pdf/10_…e_J_2013-5.pdf
aceman85turbo: (2013-04-30 03:10:42)
I would NOT drive that car, that cage is dangerous. You are brave.
here is an article explaining tube differences, http://www.xxxoffroad.com/index.php?…eral&Itemid=46
Here is an example of proper fitup
proper mig welds with good penetration, spacing and no visable welding defects(cracks or points of failure)
and a proper tig welded and gusseted cage (file too large to hotlink?)

Axel kain: (2013-04-30 03:26:00)
ok mr.safety, why not DOM for strength?
and BTW - your shoulder harnesses are wrapped entirely WRONG.
Careless: (2013-04-30 03:52:17)
looks like dynamat or something to stop the roof from buzzing/vibrating with no headliner
mazdaspeed3: (2013-04-30 17:23:23)
how are they wrapped wrong you idiot lol
mazdaspeed3: (2013-04-30 17:25:11)
i cant wait when i pass tech at vegas drift so i can prove u all wrong lol this cage was built to formula d specs he followed this article http://www.fabricatedmotorsports.com…_v20120117.pdf
slammedcoupe: (2013-04-30 18:15:00)
i can tell this is your first internetz....
ima prove all yall hatas wrong.
i know errrrythang
jaqattack02: (2013-04-30 18:23:31)
Guess whoever made it didn't read the document very well
mazdaspeed3: (2013-04-30 18:45:24)
it is made of mild steel lol
G-E: (2013-04-30 18:45:52)
For uncompetitive drift events, say in a parking lot, without tandem runs, they might let you get away without a roll cage… although these days with liability issues, that might be rare
MADMIKE: (2013-04-30 18:50:31)
Does not know difference between DOM and ERW, skipped link. Set sail for fail, friend.
stufferton: (2013-04-30 19:04:38)
Guys, it's ok. The guy who built this appears to have looked at the pitchers of cages in that pdf. Who needs to read rules and regulations about basic material to use when you have PITCHERS! It's totally legit.
Butter: (2013-04-30 20:08:41)
This cage should be fine for our drift events here. We only require door bars for tandem. Not sure what requirements he has.
ERW is fine from a safety standpoint. Our very dangerous-looking lemons car has it, and we pass the most stringent of inspections. Guess what? It's also MIG welded. DOM will probably be a requirement for new cars next year though.
Formula D cages have some pretty tarded requirements on the design.
Would I pay for this? No.
Will he be killed when his suspension fails? Probably not.
G-E: (2013-04-30 20:39:54)
Yea, his "cage" might qualify as a "roll bar" with a door bar… the rear section doesn't look like any pictures I've seen
MADMIKE: (2013-04-30 22:38:18)
I lol'd
jaqattack02: (2013-04-30 23:25:51)
Me too.
jesus94p: (2013-05-01 00:40:19)
I did too lol
turbofedz: (2013-05-01 01:16:31)
If I'm not making over 600hp or going low 10s I'll never ever do some shit like that to my baby lol…
vegasZ31T: (2013-12-11 02:22:01)
I think they missed an opportunity to really firm up the rear towers and chassis plus make the cage much stronger. For instance:
