No preload on the springs, stiffest setting on extension and in the middle on compression.
I'm hoping to get the ride height back down to where it was before switching from the Koni to the Afoc by switching to the 300 lb. springs now instead of the 350 lb. rated ones
I'm going to call Afco tomorrow and ask them why they don't cover setting the coil over preload in their instructions, I had Strange coil overs on the rear of my old Duster and their instructions called for setting them up so it had 2/3 travel up and 1/3 travel down at static ride height ready to race.
I'll post what Afco says about this on here later this week after putting the car back together with their advice results
