Well they will bolt right up to mine, but I have +2+1 a-arms. I think the R1s are the same as the R6, just a little stiffer. Regardless, whichever one you decide to use, you will need the ones with the rezzies that are mounted straight up and down, not the ones that are sideways. Also, in order to bolt it up to the rear, you will need to make some shims for the bolt holes on the dogbone and frame. The R6 shock eyes use a smaller bolt than the banshee. I can post some pics if you need me to.
