Roll cage
I thought I read somewhere a 2nd gen cage could be used in a 1st gen. Anyone try this is there any mods needed? Also I dont rember if I read the tread here or on another board. Thanks for any help.

If you check out the part numbers for the Autopower website, they list the same number for 1st gens & 2nd gens on 3 of 5 products (Street, Race, and Street-Sport Roll Bars). The cages have different part numbers, but the roll bars appear to be universal? Check the list below and share your thoughts.

Safe....sure. The bolt down pads could be a bit bigger but they work.
My two concerns are: A main hoop made to fit a second gen and first gen may not fit either one of them very well. Second is the material. 1 3/4" x .120 wall is a hefty tube. Current SCCA standard for a fist gen is 1 1/2" x .090 wall.
General rule of thumb for bolt in cages and bars has always been,
Overbuilt and fairly safe (Although, I have seen mounting feet failures)
Never really fit the vehicle tightly. They compromise the fit.
A custom cage will be better than any bolt in cage in all respects of safety and fit.

They range by area and time of year. It has been a while since I purchased DOM for cage and steel prices have risen 3 time in the last year.
I would say roughly 2K for a custom complete cage built to current specs. Add in "nascar" door bars and added bracing and you can see that jump a good bit.
I would say this would be needed for full race setups. If it is a street or autoX car I would go with just a bar. That can be had fully custom for about $500

the auto power cage is good, but it in a 1st gen in mounts to this big drain plug in the floor thats just take welded in. if you crash right, the cage just goes thru the floor.
it holds harnesses but thats about it

The mounting plates for custom cages should also hit a few vertical surfaces along with the flat main surface. The mounting plates should also be as large as possible. This is sometimes governed in the rule for the class.
This picture shows a good shot of a mounting plate. You can see how large the welded base plate is. You can also see added vertical part of the plate.
Picture is from Izzy's custom cages. http://www.izzyscustomcages.com
This next picture shows how the front down leg mounting plates were boxed up to sit on the inner rocker. Most bolt in cages are further inboard to sit on the flat floor. This causes them to take up valuable space where the driver left leg goes.
Any steel supplier can get it. They may not stock it in house, they could order it from a wholesaler.

Just wanted to let some of you know I just got off the phone with a local shop. Looks like I am getting a cage and cell install in hopes of getting my car ready for start of next season. Price is very reasonable and timelime is very flexable. Plus its local and there gonna come pick it up. All in all car will be SCCA and NASA legal and cost under $1500 parts and labor. Now I am off to look at cells so I can try and make up my mind on one os those.

Ok some info I just got from the company thats going to build my 4 point.
1.5" tubing.
We could do .095 or .120 wall thickness
Thats good right? I could go with 1.75 but they need a new die and wall thinkness could be less.
I might should post this question in the race section but I ll leave it here for now.
