The Mountune RMM has a separate spacer and uses large washers. This is all one piece. You literally pop off the bracket from your OEM and install this, no small parts
I have tried most mounts myself and have been driving around on this prototype for a while now. It's stiffer than COBB and I'd say close to Mountune, maybe a pinch stiffer but it's hard to say exactly...but again close.
We have new developments with this mount though
Originally we were just going to offer the street version as seen above in red and silver anodize using the street formula bushings
We now have the same mount being produced as a race unit offered in red and silver anodize but will have Black stiff bushings for those looking for a more race oriented mount.
2 weeks or less and they'll be here
