ello all. i want to put a half cage into my 1600 what price range am i looking for. its a hill driven car so i want some safty when i roll over. and also some thing to make the car a bit more stiff.
i have a front strut brace and the rear i will put on if i remove the fuel tank. is there any other ways i can make it more stiffer? besides seam welding.
thanks

also wats better bolt in or weld in cage

You want safety "when" or "if" you roll over?

If it's for a competition car, find out first what cage the regulations allow / require. Some classes won't let you run a half cage.

If it's for a street only car, forget it and spend your money on something useful.

Weld in is always better than bolt in.

yer its for WHEN i roll over. its not spending cash somewhere else. my car seams are splitting and i want to stop this. hence the cage also want the car to be stiffer...

its a street car anyways not real track, just hills

still need help

I say pick anpother car to ROLLOVER! 1st gen RX7 plentiful and cheap
To many get rolled here in the states still. Pretty soon none (510s)will be left.

Remember MadMax? The Last of the Datsun 1600s(Ok I changed it)

hey Spandex,

There's a bolt in 6 point for sale on the classifieds, which has a rear cross brace. If installed correctly (Ie plating the mount points, etc) this would meet your requirements if you ever turn turtle.

A professionally welded in structual cage will always be better but if you plan to use it on the street the bolt is more legal and can be removed if defected. In NSW a 4 point cage is fine as long as it doesn't obstruct doorhandles, window winders etc, though the front inserts (the 5th & 6th point) are definitely not legal for road use.

hahah turtle. i pissed my self when i read that. yer i dont really want to weld it in. is there a % for what a bolt on Vs. a weld in cage do for stiffness i know its hard but will it be a lil stiffer or a alot stiff if i weld it in

It will be far stiffer if it's welded in. I'd wouldn't like to give a percentage but a welded in cage is normally attached to pillars & strut towers etc giving much greater rigidity. Checkout the link below for more information.

yer that link is kinda wat i want. looks like welding is the only way.
need somethign for my 200rwks l20 motor
thanks for all the replys ppl

if the cage is for CAMS events it has to be 6 point steel. new rules for 2005. welded in is better

thanks for the replys . no its just for street and maybe some small track events. no cams or anythign needed.
if i weld is there any way of taking it out? like if i get defected or somethign
ill get it engineered if i can

removable......sure (i would consider a weld in ROPS permanent)

engineering is no problem if its built properly, but you might not legally be able to use your back seat due to access etc. My car is now strictly a 2 seater.

price wise you often see alloy bolt ins for around $150.00 second hand.
