    I run a UMI k-member. It was 33lbs. It looks a lot like the BMR one from the pic except it has 2 bars going accross instead of the one on the BMR. The UMI is the heaviest that I know of. I don't see any motor mounts on the Spohn k-member from the pic.

    UMI might be the heaviest but IMO is the best and strongest.

    the guys that owns the speed shop near me specializing in 4th gen f-bodys and vettes told me he goes with BMR because they use a higher grade of mild steel and are hence lighter because they can go with less material.

    UMI here and wouldn't run anything else, but I have no reason to go anywhere else. They sell great products, have great customer service, and good prices.

    Great comparison though
