I’m definitely in the minority here.
I’ve seen several Autopower cages that were either inadequate, ill-fitting, or needed additional modifications to improve safety.
Of course, I’m talking about full cages and not a rollbar. But it seems if your going through the trouble of welding and Autopower needs to send bigger plates, just go with a custom job. In the end, it’ll cost slightly more, but will have a much better fit, can be exactly as you/cage-builder designed it, and the quality will be much better than a mass-produced one.
I’m not here to get into a heated debate as I don’t think any of us have the technical knowledge to truly argue one way or another. I can only base my opinion on what I’ve seen at the track, what I’ve read from ppl that have either run or raced with them, and short discussions with race organizations’ lead safety techs.
All-in-all, it’s your car, your money, and I know a rollbar is significantly different that W2W racing with a full cage so it may suit your needs just fine for your intended purpose. Just adding my contrary two cents.
