I personally never considered the decade plus old RMS IFS a handling improvement solution, which others inferred because of the replacing of the time honored TB's, It was more a weight reduction/header clearance improvement IMO. Nowadays for the money, handing/improved kinematics/better wheel combos must also be in the cards for the dollar ranges at play.
This was my upgrade for the RMS LCA Pic #7
