Kit shock setup (Medium grip). Part numbers link to AMain.
Out of the box the R8.3E runs 500 cst front, 500 cst rear, on 1 hole (#R104022) front, 2 hole (#R104021) 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 White (#R837010) front, White (#R837020) rear. Stiffer springs suit high grip and big jumps; softer springs add grip on slick or bumpy tracks.
