These are for the front of the car, not sure how many settings there are I will have to ask my friend who runs QA1 Dave Goldie.Are they the 12 way compression ones? I started at 6 and just experimented. Leafs with leaf links. It would really depend on everything in your suspension. One thing I do know maybe just in my case, don't stagger the settings. Keep them the same.
I will say one thing about QA1's, they weren't kidding when you set them on 90-10 the shock stem pulls up quick. I have a new set of Calvert 90-10's and their valving isn't even close to the QA1's. Glad I bough them.
