Roll Cage Fabrication Thread

[zebra]

hahah Like I said, best I can manage with a welder is making holes in stuff that shouldn't have holes in it. But yes good cages seem to be a bit of a black art, which is why I will only ever get one from guys who have been doing/perfecting it for years

BSA, where are the rear legs welded to?

[Bsa]

Beside the wheel arch with full pen will have a cross pipe to strengthen more. Will run roof bars for passenger and drivers side which will end near the a pillar

[Roy]

Can you fit a harness bar on the bar between rear legs when you are running them beside the rear arch?

[DVS JEZ]

Good question. Part of the learning experience. We hadnt thought of the harness bar because i hadnt planned on running a harness yet. Ill upload more pics i just took later.

The rear legs are directly behind each seat in the middle so it may be possible to weld a harness tab and run two straps from a single point. ?

Or we can weld the harness bar between the main hoop

[Roy]

Yeh, harness bar in the main hoop is probably best anyway. Some argue that longer harness means in a big accident the longer belts stretch a little (we are talking mms not inches) and this flexibility reduces internal organ damage due to high Gs. Of course being shorter if the car distorts your belts are less likely to loosen as things move....but main reason I like harness bar between struts rather than the main hoop is acces and putting rims etc in the back seat even though you have a cage

Roy- didnt you remove a brown Davis cage for a Pro Fabrication cage?!??

[Johnny_B]

any plans for cages to suit different cars?

i have a s13 and am looking for a cams approved bolt in half cage with a diagonal cross bar between the rear legs and a harness bar across the main hoop.

only thing is im located in tasmania so i couldnt offer my car even as a demo

Yep, The Brown Davis cage was similar to what I have now...but I couldnt recline seats all the way back as my Momo seat is quite wide and used to hit it. Also didnt have a diagonal in the main hoop which i was worried would limit access for rims and tools. Pro Fabrications did a top job to package the bolt in cage far tighter to the body, provide a diagonal in the main hoop all whilst giving me the same, if not more rear access for storage of stuff when getting to/from the track
