Associated 1/12 springs work well when cut in 1/2.
You have to set the shock length to control droop. Some shock positions have almost no droop, some have way more so you might want to see what is happening with that.
Foam or rubber tires? Either way put some glue on the sidewall.
I used to run 90wt in the front and 80wt in the rear, but that was foams.
