Out of the box the SRX8GTe WC runs 1200 cst front, 1200 cst rear (Serpent oil), on 6 hole (#600145) front, 6 hole (#600145) 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 34.5lb Silver (#600601) front, 37lb Black (#600602) rear. Stiffer springs suit high grip and big jumps; softer springs add grip on slick or bumpy tracks.
The kit diff fluid is 1,000,000 cst front, 80,000 cst rear. Thicker front adds steering on power; thicker center sends more drive rearward; thicker rear stabilizes the car under throttle.
