My Ride: E46 sedan
E46: Roll bar + fixed bucket seats = unsafe?

I want to install 4-point roll bar, fixed bucket seats, and harnesses in my E46 sedan. I heard that A pillar is not strong enough in a rollover situation that it may cave in. In a fixed bucket seat you'll be dead, but reclining seats can fall back and save you.

I've seen a lot of related pictures but most are E30 and E36. I also heard that E46 has strengthened A pillar and this is no longer a risk. Please share your experience and knowledge. Is it safe in an E46 with fixed bucket seats but no reinforcement on A pillar?

I don't intend to install a full cage in my car, because it'll still be used on the street. Thanks!

Actually, you are only supposed to use fixed back seats with a roll bar, so you would be doing it right. Who told you the A pillar wasn't strong enough?

The last thing you want is a reclining seat to break or fold with a roll bar. You'll be ground beef in there unless you have a fixed back and harness.

In my opinion, a roll bar in a street car is completely and unacceptably unsafe. Exposed steel inside the cabin, even if covered with high density padding, is a BIG NO-NO in a street car. Simply put, no welds, no helmet, no HANS... -> no steel.

If its just a rollbar or half cage, ie no bars running down the front you are fine. Rear passengers is another thing though.

You would have to be a taller guy with freakishly short legs for this to be a concern.
