Move existing roll cage to new (identical) car? Cost effective?

I did it and it was pretty easy. I cut the top off of the wrecked car to get the cage out, then cut the cage into 2 pieces. On piece was the main hoop and door bars, the other piece was the halo and front down tubes. Welded in new base plates and cleaned up the bottom tubes to fit. While I was at it I moved the cage as far as possible to the drivers side and gained more than a half inch of helmet clearance.

 

I welded in new rear down tubes because I didn't like how they were in the old car. There is the biggest issue, almost everyone has something they would do different if you were to do a cage a second time so it's really tempting to just start over.

I have done it with ice racers. We cut the cage in a few as places as possible to remove. New base plates in the second car and then sleeve the bars. You have to make sure the rules allow this for whatever series you run the car. Sleeve is the same as a bolt in cage anyways. However we sleeve inside then weld and outside and weld. The sleeved part is stronger than the original cage. This way it is done without removing the roof of the new car.

 

Cut the main hoop and a-pillar right at the base plates. Knee bar on each side to sleeve. Make new rear uprights and door bars ( or sleeve the door bars ). And then somewhere on the halo hoop about 6 inches from the main hoop and sleeve that.

I moved one between e30s.  Cut the cage out of the old car including base plates.  Grind the sheet metal off the base plates.  Cut the roof off the new car mid pillar.  Make sure you weld braces on the new car below the cuts to maintain the structure integrity.  Drop on the new cage and weld the roof on.  Much easier than making a new cage and costs nearly nothing.  I did need to spread the new shell a little to get the cage to drop in but it popped right back in place and the roof fit back on nicely.

Keep in mind it is often easier to "clip" a damaged car. I have done this to the neon once. It took 8 hours to replace the car from the strut towers fowards, much faster than building a new car. 

 

On the neon this is easy because the k member was left intact. Using oem spot welds it is possible to realighn the clip close enough to allow suspension realignment to oem specs. 

 

The front clipped neon was wrecked last december to the point it was a total loss. Not even one crack was present at the point where the car was clipped. Devil is in the details, but done well the repair is stronger than new. Pm me if you need example pics.
