Out of the box the S35-T2e runs 600 cst front, 700 cst rear (SWORKz oil), on 6 x 1.3mm (#330562A) front, 6 x 1.4mm (#330563A) 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 75mm M3-dot 1.6x9.00 (#115164) front, 86mm L3 dot 1.6x10.50 (#115167) rear. Stiffer springs suit high grip and big jumps; softer springs add grip on slick or bumpy tracks.
The kit diff fluid is 15,000 cst front, 15,000 cst center, 5,000 cst rear. Thicker front adds steering on power; thicker center sends more drive rearward; thicker rear stabilizes the car under throttle.
