I did alot of research before I purchased mine. I must say for several reasons, go with PRM.
1. The belly plate is all one peice front to rear, except the bash plate and will not catch a seam if you you belly slide on a log or rock.
2. All of the mounting hardware bolts from the bottom up in threaded inserts on formed aluminum top plates, and the bolt heads in recessed holes in the skids, again allowing them to slide over most anything without hanging up.
3. With the formed mounting plates, there is no vibration rattle period. These plates are built heavy duty! I would not hesitate if I was still into racing, to race GNCC's with these in the rockiest course known to man at speed!
4. They require no modification to bolt up, and come with everything you need.
PS. I do not work for or recieve any kick back from PRM, they are really just that far ahead of the other companies. The primarily build stuff for racing conditions, and it shows here.
