Agree with both of you, I'll probably just opt for the IRO, with bracket, which will eliminate all issues with my coils rubbing, no matter the caster angle and then sell the JKS.
I thought about lobbing off the end of the JKS, and installing IRO's double sheer "upgrade" but I figure for the amount of work necessary, and the issues that could come from it, such as fitment issues, better off just going with tried, and true.
