Stop in for a cup of coffee

k guys.. couple of things... was cleaning my torsion bars and they are .900 and have pitted rust... this car will do well over 30mph and not worth taking a risk... Are 1.04s too stiff? don't wanna ride like a truck... also any one brand better than the other? i have a hard time trusting new parts :(

Also... was fitting my brakes/lcas and all that... and the caliper bracket and lower ball joint came with this black coating that almost feels powdery but doens't wire wheel off too easy.. any chance this stuff will stop rust or should i hose them down with some black paint?

also i assume it will be much harder to get the torsion bars in if i put in the LCAs first?
