QA1's level 2 Suspension Kit (like/dis-likes?)

I'm wondering if anyone has made the plunge and converted their A-body stock k-member, upper/lower control arm and sway bar, etc... to QA1's Handling package Part# QA1-HK12-CRA1? If So...
Are you happy you went with it?

My k-frame needs repair and I cant do the welding so will have to pay to have it done at FFI or have someone local weld the seams and add FFI gusset kit and also want to box the LCA's too...either way were talking $$$'s,

thanks for any response!
