New rsm question

[CircuitMonster]

So I've narrowed it down to either picking up the Ireland engineering rsm or the rouge rsm. I know the rouge rsm make it so you can now access everything from the wheel area without tearing up the trunk interior. My question is the Ireland engineering ones the same or is it like the stock setup just polyurethane.

Also which ones seem to be the better of the two. Any input would be great.

And yes I have read and searched for info on rsm's that's why it has been narrowed to these two. I just want your thoughts and info.

Thanks.

The only difference between them is the bolts are tack welded to the upper reinforcement plates on the Rogue pieces, but this is negated when you look on the IE z3 section, there they are listed as tack-welded.

other than that, yellow zinc vs. silver zinc? soft urethane or rubber?
