I have a Dinan Stage II waiting to get installed. The one thing I don't like about the Dinan camber plates is that it seems like a compromise. I could be wrong but I think that -2.5 camber up front is not enough especially considering the weight and the R Comp tires.
Maybe an idea, I am thinking about going with the GC Camber plates instead of dinan. The bad part is the bottom of the mount is not shaved like the Dinan mounts so you lose the extra .3" in travel with the GC plates. I have to call GC sometime to see if shaving the bottom of the mounts is possible.
