I have a 88 hatch back this car is my back road car wen i take hard turns i noticed my dome light was turning on. My friend in the passenger seat said he could actuly see the car flex likeainch and ahalf. Im going to buy upper and lower tie bars front and rear and a b piller bar, will tgat fix the prob or is there anything else i can do to help the flex? Im runnin function form coils si front sway bar integra rear disck's type r rear sway bar.

 

6-8 point cage, or take everything out and spot weld the car.

on a serious note, if you car is flexing that bad, might be time to find a new shell.

 

Ya thats what i was afaid of i realy dont want to get a new shell and i was 50/50 between building a cage for it cuz ill have to buy a welder/tubbing bender but i think that might be my best option

 

Is there anyplace that sells pre bent tubes that i can just weld up or should i just buy some pipe and desine my own?

 

If you have the skills to fabricate and know the regulations then go for it.
I read that you mentioned buying a welder and tube bender that tells me either you never built a cage or you used to.

If you are taking your first stab at welding pick an easier project. Tube benders cost mad cash. My tubing die and follower alone costed 450'n built my own bender with plans from gottrikes.com
I ended up spending about a grand total on that set up. My home welder is a lincoln 180 mig which I love because I got it for 500 brand new (ebay auction ftw!).
Then there is tube notching. I got a crappy harbor fright deal for 25 bux that worked good until the bronz bearing went to shat and started notching sloppy.. Then I said "f" it and took a risk on a knock off plasma cutter which works awesome for notching and clean cuts 1/4 plate no prob I only had a switch go out on it no biggie.

I got carried away but what I'm trying to say is that if you have the money and want to buy the toys to fabricate more stuff later on go for it.
Tools are never a waste of money imo. But if it is just for that one job I say buy a pre bent bolt in cage. There are reputable dealers on ebay and it won't cost you near as much as buying all the tools and paying for welding classes so you can weld uniform beads with good penetration and not end up on the "worse fab pics" thread.

 

I appricate ur input and Ya i know its gona take some money to get the tools to build a good solid not tomention planning and yes this would be my first cage build i have a little welding experince but i love to fabricate stuff nothing better wen some1 asks you where u bought that and u can say i didnt buy i made it.its just a great skill to have
