Certifed / not certifed roll cages???
Hi, my son and I are looking for a race car to run SG/SP/NE. I have looked at a mid 70's Vega that needs some body work, but have yet to talk to the owner. I noticed in the classifieds here that a lot of the adds state that the roll cage is ceritified, not certified, or in some cases not certifiable. I've been out of racing for a long time and I can remember when cars got "teched" at the track that the roll cage had to be of a certain thickness and there had to be a place drilled in the cage so this could be measured. Has it gotten a lot more "to it" than that now? What can cause a roll cage not to be certifiable?
