that front halo is weird, it stops pretty far back from were the window and roof actually meet. (at least thats what it looks like in the pictures.

looks pretty safe to me
it's about the cage not the roof and window
what is going to save you?
the cage, or the "point where the roof and window meet"?

 

For some reason i thought i reconized that place....

 

lots of it may not be legal for scca or nasa, etc. but i liked how it illustrated several "tricks" that we sometimes discuss such as:

dry ice to remove crap,

cutting a hole in the floor to drop the cage for access to welds, etc.

never said it wasn't structurally sound or unsafe. Just weird. In all the cars i have seen the upper window bar is much further forward. This is Road race cars though, from ALMS, Speed WC, and GA.

 

what do you mean weird?

The other way to do it would be by moving it forward on the upper a pillar which moves it out of the plane of the rest of the bars. If it were up too me I would have done it as is due to the design of the unibody, this seems a lot better of a choice.

Here's thing thing to move the front upper bar forward would require moving it down the a pillars right? so then it will be a single bar on its own in a crash situation; as opposed to have the x and other bard there to support it.

this was also in a WRX,

Did anyone other than me notice there were alot of welds done with silicone bronze (and it says that was in the list of welding rods)

Man I know how that stuff doesnt hold up for poo on a manifold holding a turbo together I would really hate to be in a wreck and that is holding the cage

the bronze filler is for the places there are welds to the oem chassis, like the dimpled plates.

 

How would this work in SFWD since everything has to be stock from the front seats to the dash? Do the OEM side pillars need to be in place?

 

Even in this case I dont understand it
The factory material on the car is mild steel the same as the rest of the material in the cage why use a weaker unsimilar filler in this case?

nice article
