I am using the stock big bore Mugen shocks that came with the XRworks. They aren't too expensive and I am sure they would fit your buggy too. They are like 40$ a set, with nice chrome springs and spacers. I used to be a big fan of the coil overs too, until I figured out the threads get dirt in them and then when you adjust the collars it destroys the finish on the shock shafts. I like the spacer type better now, and they adjust MUCH quicker too!
