Nick Caro has asked me about these, has anybody tried the new IFW405 (-128, -138, -148) tapered pistons in their 8th buggy? Particularly the MP9 but these will fit any big bore shock.
They look very good, and I hear aid smooth shock movement with good damping from large jumps. Im yet to try them, will be ordering them soon but intrigued to here is people have tried them already and in what sizes.
