I was discussing coilover spring rates for the QA1 setups with one of the UMI techs today after seeing that they provide the same garbage recommendations that QA1 suggests on their site. Apparently they don't follow those recommendations when they actually talk to their customers and they're working on some fun stuff for the S-series that should be released soon.
Straight from the tech:
"We have 850's on our Afco coilover setup which works in conjunction with our new fancy coilover arm - debuting literally any minute now.
We also have a double shear upper mount coming very soon so you can run any real 7" racing shock and spring..."
I like that sound of that second option, I'm tired of coilovers.
