Kit shock setup. Part numbers link to AMain.
Out of the box the E819RS runs 42.5 wt front, 32.5 wt rear (Team Orion oil), on 5 x 1.4mm front, 5 x 1.4mm 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 Gold 79.6gF (#109810) front, Blue 61.6gF (#109814) rear. Stiffer springs suit high grip and big jumps; softer springs add grip on slick or bumpy tracks.
The kit diff fluid is 7,000 cst front, 5,000 cst center, 3,000 cst rear. Thicker front adds steering on power; thicker center sends more drive rearward; thicker rear stabilizes the car under throttle.
