Kit shock setup. Part numbers link to AMain.
Out of the box the IF18-III runs 600 cst front, 600 cst rear, on 1 x 1.3mm (#R0142) front, 2 x 1.1mm (#R0143) 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 Stealth 9.5 (#SMJ1226) front, Stealth 7.6 (#SMJ1227) rear. Stiffer springs suit high grip and big jumps; softer springs add grip on slick or bumpy tracks.
