Kit shock setup (Ultra Outdoor Asphalt). Part numbers link to AMain.
Out of the box the Cero Ultra/ACE runs 450 cst front, 450 cst rear, on 4 x 1.1mm front, 4 x 1.1mm rear pistons. That is the kit setup; you will need to adjust it for your track conditions. The RC Setup App can help dial it in.
The kit springs are 2.8C Green front, 2.75C Orange rear. Stiffer springs suit high grip and big jumps; softer springs add grip on slick or bumpy tracks.
