I don't get how people say they feel one works better than the other. The RRM and the DC aren't bowing, so the ride's the same. Then it gets down to material and mounting. Sorry, but I'd rather have the carbon steel 6 bolt mount on my DC. If the RRM was a 6 bolt, I would've bought that. Other strut tower bars that are flat bar (not tubular) may be bowing and give more than a rigid bar. I seriously doubt I'd want a 3 point bar. I think if you immobilize to much of the strut towers, it may not be desirable. But hey, I'm no suspension engineer. it IMO
