Default Which 4l80 crossmember to use? MWC, BMR etc

I'm looking to find which 4l80 crossmembers people are using and what they recommend. I'm looking for great fitment and preferably light. I do not need a torque arm mount on it as mine is located off the crossmember.

I do know that MWC makes a chromoly one, but i'm not sure if anyone else does. Weights would be good to know too. This is for a 4th gen f-body.

Let me know your thoughts

Thanks,
Josh

I used the bmr one and had to mod it some to get it to fit because it was hitting the pan.

Back a while ago we had some crossmembers that had to be modified to fit so it didn't hit the rail. Since then we have redesigned the crossmember and there is plenty of clearance to use our BMR crossmember with a 4L80E without any issues. If you guys have any questions or if there is anything I can do for you guys let me know.

There were only a couple that had issues. Most people that bought them installed them without any issues.
