The Strictly Street coilover mounts are much more stiffer than the XII mounts. But you could just swap out the coilovers and use the XII mounts. The stock springs are 550ppiSorry to ask this I hope it is not insulting, If I am thinking of changing out my qa1's on my truck with the XII mounts, is there a good reason to change the mounts not just swap the coilovers to the Viking shocks? and how much stiffer is the 650 than the stock spring?
